LHCb is an experiment at CERN’s Large Hadron Collider (LHC) operating since the fall of 2010. During the RUN-I and RUN-II it has taken data at √s=7 TeV (2011), √s=8 TeV (2012) and √s=13 TeV (2015-2018), showing extraordinary performance and integrating a total of 9 fb-1 of data. From the end of 2018, LHC underwent into a scheduled shutdown (LS2) and an upgraded LHCb detector will be installed and commissioned, starting the RUN-III data taking in 2021 until 2023. This phase-I upgrade will employ a 40 MHz readout with a very flexible software-based trigger, which will provide significantly increased efficiency in hadronic final states, and allow the experiment to function effectively at the higher luminosity of 2 x1033 cm-2s-1, doubling the signal efficiency of the physics channels. The upgraded detector is expected to offer the experiment the capability to trigger on new interesting signatures, such as long-lived particles, opening new physics opportunities.
The timescale of the proposed PhD thesis (2021-2025) implies the physics exploitation of the already accumulated RUN-II LHCb data, the installation, commissioning and maintenance of the phase-I upgrade detector, the operation of the detector and exploitation of RUN-III data. In addition, opportunities to participate in the R&D activities for the phase-II upgraded detector after RUN-III might as well be considered.

- Active Galactic Nuclei in Merging Galaxies: A theoretical Approach[+]
Group Leader: Josep Maria Solanes Majúa
http://icc.ub.edu/people/68Research Project Description
Supermassive black holes (SMBH) have been detected in the centers of most nearby large galaxies. Galaxies today are not only the products of billions of years of ierarchical structure build up, but also billions of years of SMBH activity as active galactic nuclei (AGN) are thought to be the generic outcome of galaxy-galaxy mergers. In this context, detection of AGN pairs should be relatively common. Observationally, however, dual AGNs are scant, being just a few percent of all AGNs. In this PhD thesis, the candidate will investigate the triggering of AGN activity in merging galaxies via a suite of high-resolution hydrodynamical simulations. (S)He will follow the dynamics of the mergers and trace all processes related to star formation and the accretion of baryons onto the SMBHs, exploring AGN activity across a wide range of relevant conditions and testing when the two AGNs are simultaneously active and for how long. One of the main goals is to derive constraints for the dual AGN fraction detectable through imaging and spectroscopy.
This thesis is part of a joint research project which involves researchers from the ICCUB and from the Instituto de Astrofísica de Andalucía (IAA) and the Instituto de Astrofísica de Canarias (IAC), both Severo Ochoa Centers of Excellence. This partnership, has been awarded funding by the Spanish Programa Estatal de Fomento de la Investigación Científica y Técnica de Excelencia over the period 2017-19. ICCUB’s contribution to this project mainly lies in using state-of-the-art computer simulations of galaxy interactions and mergers to capture much of the important physics of the processes involved on timescales affordable to study, thus providing a valid reference against which to compare observational data. In short, we are offering the opportunity to participate in a multidisciplinary endeavor that will allow students to acquire advanced academic training in diverse fields, from theoretical astrophysics to high-performance computing.
Job Position Description
The PhD candidate should start by familiarizing with the numerical tools and high-resolution collisionless simulations developed by our group, and then contribute to the implementation of the hydrodynamic modeling of the astrophysical dissipative processes related to the gas cooling, star formation, and feedback in galaxies that have a direct bearing on the feeding of their central SMBHs during a merger. (S)He will then perform and analyze a massive suite of numerical simulations of binary galaxy mergers, focusing on the separations and timescales characterizing dual AGN activity. On a later stage, the candidate is also expected to contribute to the extension of the implementation of the evolutionary equations for baryons to forming galaxy groups, in which galaxies experience multiple collisions and mergers with other group companions, as well as strong interactions with the intragroup environment. The goal of this phase would be to build on the knowledge of the formation scenario of first-ranked objects in galaxy aggregations.
In order to succeed in his/her task, the candidate will have to deal in a totally self-consistent manner with numerical simulations that combine dark, stellar and multiphase gaseous components, and that have a high enough resolution to minimize the effects linked to the two-body heating, angular momentum loses and alterations of the radiative cooling efficiency. In this context, it is worth noting that our group owns a large parallel supercomputer with 40 CPUs and has preferential access to the massive computing infrastructures of the IAA and IAC, where the PhD student will also be expected to carry part of his/her work. This allows us to guarantee that at all times there will be enough computing power available to perform the numerical simulations required by the thesis.
Individuals with good analytical/research skills and interested in acquiring a high degree of computer literacy are encouraged to apply.
- A numerical and semi-analytical approach to study the radiation from powerful astrophysical outflows[+]
Group Leader: Valentí Bosch-Ramon
http://icc.ub.edu/people/178Research Project Description
Understanding the astrophysical sources producing ultra-relativistic particles and energetic radiation requires the characterization of the underlying physics, which typically involves complex fluid dynamics, particle acceleration, and radiation processes. This characterization has traditionally relied on models based on strong simplifying assumptions on the emitting region. The recent great improvement in observational instrumentation has slowly pushed the field towards more complex theoretical models, and now it is time to work on fluid dynamics accounting for the production of ultra-relativistic particles and their radiation.
The project is focused on: (i) getting familiar with semi-analytical modelling of nonthermal emission (ii) working with relativistic magnetohydrodynamical codes to include the presence of very energetic particles and their emission; (iii) application of these tools to powerful galactic and extragalactic sources that feature interaction structures (binary systems, active galactic nucleus jets, etc.) that are expected to strongly radiate gamma rays and lower energy emission; (iv) to compare the accurate computational results with observations of these sources.
The research group is oriented towards the theoretical modeling of very energetic sources in the Universe. The group leader, Dr. V. Bosch-Ramon, has been working for many years on galactic and extragalactic sources, and has a long experience and knowledge of techniques applied to model these objects. The research group is embedded in a worldly recognized group (part of MAGIC and CTA: VHE instrumentation), led by Prof. J. M. Paredes; the group also hosts other prominent senior scientists, with decades of experience in multi-wavelength observations from radio to gamma rays: the perfect context to plan observations to provide the theoretical research with observational feedback. The research will be carried out in the framework of a powerful international net of collaborators all over the world.
Job Position Description
The job position requires some modest experience with structured programming. At least basic understanding of special relativity and fluid dynamics is important. A working knowledge of English is also needed. It is also important to be open to attend conferences and carry out research stays abroad. Finally, what is mostly needed is motivation for solving interesting, but surmountable, physical problems, to work hard, and to learn team work, as well as analytical and synthesis skills.
There is an important multi-disciplinary element in the job position, as it links basic physics disciplines with applied astrophysics, i.e fluid dynamics in extreme conditions, modeling of radiation from astrophysical sources, and interpretation of observations and planning for prediction testing.
The doctorate schedule may be organized as follows:
- The doctoral fellow will develop semi-analytical models and extensions of powerful codes for relativistic magnetohydrodynamics. These extensions will take into account the generation, transport and energy evolution of ultra-relativistic particles in the simulated flow. This tool will permit sound and consistent modeling of powerful and complex sources, not well understood yet. In parallel, the fellow will become familiar with relativistic hydrodynamics, and non-thermal processes. This task would last up to the end of the first half of the PhD.
- The fellow will apply the developed tools to hot topics in high-energy astrophysics, like gamma-ray production in galactic systems and in extragalactic jets. In parallel, the fellow will become familiar with the observations carried out to study these sources in the whole electromagnetic spectrum. This task would start towards the end of the first year.
- The fellow may take part in observational campaigns to observe the modeled sources,and participate in the proposal stage as well as in the interpretation of the results.This activity could take place during the second half of the doctoral period.
- Front End electronics for medical imaging and particle detection[+]
Group Leader: David Gascón
http://icc.ub.edu/people/30Research Project Description
The experimental particle physics (EHEP) research team in the Institute of Cosmos Science in the University of Barcelona (ICCUB) has contributed to heavy flavour experiments during the last 17 years. During this time, the group has developed a significant expertise in the design, manufacturing and operation of custom electronics and microelectronics for the readout of photo-detectors and data processing in other disciplines, such as astrophysics, space or medical imaging.
The technology developed for the particle physics experiments has been proved to be disruptive for Positron Emission Tomography (PET) in the medical imaging field. Current full-body PET scanners can achieve a 300-ps FWHM Coincidence Time Resolution (CTR) and nowadays the best results found so far could be near 200ps, which can be translated into 3cm spacing resolution. The dream in PET scanners could be to reach the 10ps CTR, i.e., a spatial resolution of 1.5 mm. This 10-fold increase in sensitivity will translate in the reduction of radiation dose, scan time, and cost by an order of magnitude. One way to get closer to the 10-ps CTR is to employ very deep submicron (VDSM) technologies (below 65nm) to develop ultra-fast readout electronics. However, these VDSM processes pose challenges, in particular to the analog front-end (FE) design.
The main research activities will be:
- Study different VDSM CMOS technologies and select the most appropriate in terms of performances and cost.

Group Leader: Joan Mauricio Ferré
http://icc.ub.edu/people/326Research Project Description
The experimental particle physics (EHEP) research team in the Universitat de Barcelona has contributed to heavy flavour experiments during the last 17 years. During this time, the group has developed a significant expertise in the design, manufacturing and operation of custom electronics and microelectronics for the readout of photo-detectors and data processing in other disciplines, such as astrophysics, space or medical imaging.
Positron Emission Tomography (PET) is a diagnosis technique that employs a small quantity of a radioactive substance to obtain molecular images of a living organism by measuring the Time-of-Flight of photons produced by electron-positron annihilation. Commercial full-body PET scanners currently achieve a Coincidence Time Resolution (CTR) of around 300 ps FWHM, i.e., 7.5 cm. Although, there is a lot of effort in decreasing this number, nowadays the best values are around 200 ps, i.e, 3 cm. One of the main challenges in medical imaging is to develop improved readout electronics to get a bit closer to the single photon time stamping at the level of 10ps FWHM, i.e., 1.5 mm intrinsic position uncertainty, which could open the way to paradigm shifts in medical imaging applications.
A PET system is composed by scintillators, photo-detectors, front-end electronics and back-end electronics to ease the data processing. Front electronics require a fast response to capture precisely the arrival time and energy of the photons generated by a gamma source. The front-end electronics must provide time and energy information into a binary pulse, but this information must still be converted into a digital representation of the time they occurred. Time to Digital Converters (TDCs) are traditionally used for this purpose. In that sense, readout electronics should be designed using very deep submicron (VDSM) technologies (down to 28 nm) to develop ultra-fast TDCs. However, these VDSM processes pose challenges, for instance, in terms of process variations.
Job Position Description
The candidate will join the group as a fellow researcher in the Integrated Circuit (IC) design field. This position will focus on developing the back-end electronics, i.e., the TDC, for the electronics of a PET system. The objective is to develop a high density TDCs, including 64 readout channels, with a time stamp with a resolution lower than 10ps and decreasing drastically the power consumption up to 1mW per readout channel. This big decrease in power consumption could be achieve, partially, by employing deep submicron technologies, 65nm and below. The candidate will need to tackle the problems of these technologies, such as process variations which directly translate into performance degradation if the layout is not designed properly. Another challenge will be to integrate the back-end electronics with the front-end electronics into a single chip in to increase the level of integration. Lastly, The TDC could be also applied to future high luminosity colliders, where picosecond time resolution is required for time tagging of particle interactions or other applications such as LIDAR.
She/he will participate in all phases of IC design flow (design, simulation, layout and verification) and characterization of the modules in lab test benches and particle detectors. The candidate will work in a multidisciplinary environment involving also scientists and international researchers.
The requisites of the candidate are knowledge and experience in:

The Physical Cosmology group (icc.ub.edu/~liciaverde/ICC-Phys.Cosm.html) has been working in Cosmology, connecting theory with observations via interpretation of data since 2007. Our main research interest is making the connection between cosmological observations and the physics behind the standard cosmological model, hoping to shed some light on the “open questions” in cosmology: what is dark matter, what is dark energy? What are the neutrino properties? Is there new physics beyond the standard model for cosmology (which members of the group have actively contributed to establish some 15 years ago or so). Our collective expertise ranges from galaxy evolution to inflation model building but our main strengths are in analysis and interpretation of large-scale structure surveys. Members of the groups are involved in the DESI survey and the Euclid consortium. These are highly international collaborations. In particular the DESI survey is expected to produce data on a timescale shorter than the studentship offering a unique opportunity to exploit these data. We have tight collaborations also with several groups abroad including in Italy, France and UK. In 2018-2019 the group will be composed of two Faculty, one postdoc fellow, three postdocs, and five graduate students, offering a diverse and vibrant learning and research environment.
Job Position Description
The current understanding of the Universe is incomplete. According to the standard cosmological model, its dynamics are governed by two components, dark matter and dark energy, for which we only have indirect evidence and fragmentary theoretical comprehension. Unveiling the nature of this dark sector likely requires either a modification in the standard description of fields and particles or an advancement in our understanding of space and time (by modifying Einstein's General Relativity).
Next-generation galaxy surveys, such as DESI and Euclid, will play a crucial role in disentangling these two competing scenarios. Together with existing low redshift dataset, these new surveys will provide us with an unprecedented amount of 3-dimensional galaxy clustering information and growth of primordial cosmological perturbations under gravity. The combination of these two probes is key in addressing the big open puzzles introduced above.
Next-generation surveys aim at an order of magnitude improvement on current cosmological constraints coming from these two key measurements, but, for this to be possible, we have to face a number of challenges. Chief among them is modelling non-linearities in an accurate yet fast way. We envision that a combination of analytical and numerical approaches will be needed, in particular on the modelling of the so-called redshift space distortions. A potentially powerful model was originally introduced by members of this group and there is ample room for further developments.
You will be working with the group on advanced modelling of non-linear scales from both a theoretical and numerical point of view. The results will be a key step in understanding the unprecedented amount of cosmological information that next-generation survey, such as DESI and Euclid, will deliver.

Job Position Description
This project is oriented in develop blinding techniques for the upcoming cosmology surveys, with special emphasis in DESI and Euclid. Since the major science results from these surveys (e.g., determinaton of neutrino masses, informaton on the mass hierarchy, nature of dark mater, nature of dark energy) have profound implicatons for Fundamental physics, beyond cosmology, the same rigorous standards employed e.g. in partcle physics must now also be applied in Cosmology.
Blinding is a well developed technique in science and in partcular in partcle physics whereby informaton about the test or measurement is masked (kept) from the experimenter, to reduce or eliminate bias, untl afer a trial outcome is known. Its applicaton is wide even beyond physics, for example it is used extensively in medical trials. Blinding has not really been implemented much in cosmology untl very recently and it has not been applied in the analysis of galaxy surveys. But in the era of accurate and precise cosmology it must become a priority for all ongoing and future surveys. Implementng blinding in galaxy surveys analysis opens up a whole new series of challenges which must be addressed to ensure high quality of the scientfc results. Having not only precise and accurate measurements, but also unafected by the prior cosmological analises, is one of the key aspects of to ensure that the fundamental questons that these projects can be answered, and can be directly imported into the other felds they can impact (fundamental physics, partcle physics etc.). You will work with the group and the DESI team on addressing these challenges and on developing and implementng a blinding strategy for DESI. This will be a critcal item in the path to ensure success and recogniton of the experiment.

Job Position Description
This project aims to study the content of the Universe, its nature and laws through the large scale structure (LSS) of the Universe.
One of the most outstanding breakthroughs in the recent history of physics has been the discovery of the accelerated expansion of the Universe, initally via observatons of Type Ia SNe, which was awarded with the Nobel Prize of Physics in 2011. Within General Relatvity, such accelerated expansion can only be included through a positve value of the cosmological constant, which counterstrike force of gravity. Such cosmological constant could be understood as the presence of an exotc form of energy associated to the quantum vacuum, which is usually referred as Dark Energy. Within this framework, the current state-of-the-art observatons suggest that only the 4% of the energy-density content of the Universe is made of partcles we understand at fundamental level, whereas the remaining 96% seems to be dominated by exotc forms of mater and energy we are just startng to classify and characterize. What makes up 96% of the Universe? These are the biggest open questons in the feld, and some of the biggest open questons in physics today. In this project you will address such big open questons through the LSS of the Universe, and in partcular with the future massive galaxy surveys, the Dark Energy Spectroscopic Instrument (DESI) and EUCLID. This project focuses on how to maximize the scientfc outcome LSS data that these DESI and EUCLID will deliver. In partcular you will focus on, i) to compress and optmize the amount of informaton that we can extract from observatons or experiments, ii) to use higher order-functons to increase the informaton return from these experiments, iii) to develop new techniques to control and correct the systematcs that otherwise would limit the promised precision of these experiments, vi) to study ways of improving robustness of interpretaton of cosmological results and its wider implicatons.

Job Position Description
The avalanche of data that current astronomical surveys are bringing, allow for precise exploration of the fundamental laws of physics. What was the origin of the early Universe? How did the Universe evolve to our current state? What is Dark energy? Are there extra-dimensions? Is the Universe homogeneous? What lies beyond the current visible horizon? Many of these questions can be answered by a detailed study of data from the sky and a careful theoretical analysis. This projects lies at the most exciting frontier of knowledge currently: cosmology; it will provide the PhD student with a golden opportunity to exploit the golden trove data that is arriving from telescopes worldwide to unveil fundamental laws of nature. The project aims at using data from current and upcoming cosmological surveys like DESI and EUCLID to explore the above frontier of human knowledge. In particular the student will develop tests and make predictions that can shed light into new physics by exploiting observations of the large scale structure of the sky.

- Star formation in the Cosmological Context.[+]
Group Leader:
http://icc.ub.edu/people/103Research Project Description
Star formation is a crucial process in Cosmology, to understand the re-ionization of the universe and the origin and evolution of galaxies. This PhD project tackle star formation by addressing fundamental questions of its role in the cosmological context: What physical processes control the distribution of stellar masses and the formation rate of stars and how do they change with cosmic time? What was the contribution of the very first stars to the re-ionization of the universe? Do globular clusters probe the early merging activities of mini halos in the standard cold-dark-matter model of the universe?
The research project consists of developing state-of-the-art computational models, focusing on two key contexts: 1) Magneto-hydrodynamic, cosmological simulations of the first dark-matter halos to collapse and form stars, to study the origin of Population III stars and their possible role in the re-ionization of the universe; 2) Simulations of the collision and merging of mini halos at high redshift, to investigate their possible role in the origin of globular clusters.
These are challenging multi-scale and multi-physics computational problems, requiring state-of-the-art massively parallel codes and large supercomputing allocations. The development of numerical codes is an important part of this project, which is carried out in close collaboration with the computational astrophysics group at the University of Copenhagen. The group in Barcelona will be composed by Prof. Padoan (group leader), Dr. Frimann, the PhD student, and long-term visitors from the University of Copenhagen. The main collaborators in Copenhagen will be Prof. Nordlund, Prof. Haugbølle. We have a proven track record in the field of computational astrophysics, leading the most challenging supercomputing applications in supersonic turbulence, star formation, solar physics, and plasma physics. We are regularly awarded some of the largest allocations in supercomputing facilities in the USA and Europe.
Job Position Description
The PhD student who aspires to lead this project will have a keen interest in fundamental astrophysical processes, a demonstrated aptitude for the development and adoption of numerical codes, and a steadfast determination to become a world leader in the field of star formation, with seminal and transformational contributions.
Though not a strict prerequisite, expertise in cosmology, hydrodynamics, plasma physics, turbulence theory and interstellar radiative processes is desirable. Good knowledge and experience with programming languages is required.
The student will lead the development of specific code modules, the set up of numerical simulations and the analysis of their results. She/he will also collaborate in the preparation of supercomputing proposals and will be the leading author of at least two publications per year in the second and third year of the project. The student will attend international conferences, workshops and focused schools on computational methods. She/he will spend part of the time at the Star and Planet Formation Center at the University of Copenhagen, to collaborate in the development of a new hydrodynamic code designed specifically for future exascale supercomputers.
Because of the multidisciplinary nature of this project, requiring expertise in cosmology, interstellar medium physics, star formation, magneto-hydrodynamics and computational methods, the student is expected to interact with different research groups within the Institute of Cosmos Sciences at the University of Barcelona and at other research centers abroad. Besides the collaborators in Copenhagen, the student will interact with researchers from the University of Helsinki (implementation of radiative transfer codes), Harvard University (physics of turbulence), University of Lund (origin of planetesimals), NASA Ames (modeling of dust evolution), Max Planck Institute of Munich (chemistry of protoplanetary disks).
- The Origin of Terrestrial Planets[+]
Group Leader: Paolo Padoan
http://icc.ub.edu/people/103Research Project Description
What sets the stage for the formation of rocky planets, possibly hosting conditions favorable to the emergence of life? Planets are the result of the evolution of dusty gaseous disks around young stars born within large clouds of cold interstellar gas containing thousands to millions of solar masses. To model ab initio the formation of protoplanetary disks we must develop a computational framework that captures the complex environment of star forming clouds, including the coupling of turbulence, magnetic fields, stellar radiation and gravity over a vast range of scales.
The project is composed of two parts: 1) Large-scale simulations of star-forming clouds, to achieve a realistic description of initial and boundary conditions for a large number of young stars and their circumstellar disks. 2) Simulations of dust evolution in protoplanetary disks, embedding billions of inertial particles, to study the transport and evolution of dust grains coupled with the gas dynamics self-consistently.
These are very challenging multi-scale and multi-physics computational problems, requiring state-of-the-art massively parallel codes and large supercomputing allocations. The development of numerical codes is thus an important part of this project, which is carried out in close collaboration with the computational astrophysics group at the University of Copenhagen. The group in Barcelona will be composed by Prof. Padoan (group leader), Prof. Estalella, Dr. Frimann, the PhD student, and long-term visitors from the University of Copenhagen. The main collaborators in Copenhagen will be Prof. Nordlund, Prof. Haugbølle and Prof. Jørgensen.

- Astrophysical signatures of wave dark matter[+]
Group Leader: Jordi Miralda-Escudé
http://icc.ub.edu/people/95Research Project Description
The proposed research focuses on investigating the nature of the dark matter, which comprises about 84% of all the matter in our Universe according to the most recent measurements from the Cosmic Background Radiation fluctuations. Two approaches are proposed for the research: in the first, the consequences of the presence of axions with a mass of the order of ~10(-22)eV as a component of the dark matter will be studied. Axions of this mass should behave as wave systems and would exhibit phenomena that are familiar in atomic physics but on the scale of a galaxy. Specifically, the research may focus on the impact of dynamical relaxation of dark matter in galaxies if all or part of the dark matter is axions of this very low mass. Predictions from this model can be confronted with observations of stellar dynamics in dwarf galaxies, as well as gravitational lensing in clusters of galaxies.
A second approach would be to study alternative observational techniques through which the nature of the dark matter can be probed, including the possibility of the QCD axion, with a mass or order 10^(-4) eV. An example is the nature of Fast Radio Bursts, which are brief and powerful radio bursts that might be produced by clumps of QCD axion dark matter when colliding with neutron stars. The physics of dynamical relaxation in axion halos mentioned above also has applications to study the density profiles of QCD axion dark matter clumps that are predicted to form from small-scale isocurvature fluctuations in the dark matter density.
Job Position Description
The fellow joining this research program would collaborate in all aspects of the research, and would be trained in the required techniques for numerical calculations, cosmological simulation analysis, or observational data analysis that are required. The proposed topic of the nature of the dark matter is fairly broad and the fellow would have freedom to develop the project in the direction that is most promising and appealing. Required skills are a strong background in fundamental physics and mathematics for numerical analysis.
- A multi-messenger view of the extreme Universe: photons, neutrinos and cosmic rays from ative galactic nuclei[+]
Group Leader: Matteo Cerruti
http://icc.ub.edu/people/68Research Project Description
The origin of the cosmic radiation, a flow of charged particles that constantly hit the Earth, remains, a century after its discovery, one of the major open questions in physics. This is especially the case for the ultra-high-energy cosmic rays (UHECRs), particles with E > 1018 eV. Their origin is likely extragalactic, and their very detection reveals the existence of extremely powerful and efficient cosmic accelerators. Yet, none of them has been clearly identified. With the discovery of active galactic nuclei (AGNs) and quasars at the beginning of the XX century, and the understanding that their extremely high luminosity is due to interaction of matter with a super-massive black-hole, these objects became an obvious candidate to explain UHECRs.
A powerful tool to investigate the sources of cosmic rays is multi-messenger astronomy: if cosmic rays are accelerated in quasars’ jets, they interact with low-energy photons producing mesons which then decay to photons, leptons and neutrinos. Cosmic ray acceleration is thus inevitably linked to the emission of gamma-rays and neutrinos. On 09/17/2017, IceCube and the gamma-ray instruments Fermi-LAT and MAGIC, observed the first evidence (at the 3 sigma level) of coproduction of photons and neutrinos from an AGN. This event has sparkled interest on AGNs as neutrino emitters, and thus cosmic-ray accelerators. We are currently at a turning point in gamma-ray astronomy: the current generation of Cherenkov telescopes will make way for the new Cherenkov Telescope Array, CTA, which is currently under construction and will be fully operative in the next decade. During the next three years the early CTA data will be available, fostering the first multi-messenger studies in this new era of gamma-ray astronomy.
The ICCUB is one of the leading laboratories in the Spanish gamma-ray community, with leading roles both in MAGIC and CTA, internationally renowned for its contributions to high-energy astrophysics and gamma-ray astronomy.
Job Position Description
The candidate will take an active role in the MAGIC and CTA Collaborations. He/she will have immediate access to MAGIC data, and will perform data analysis on AGNs and IceCube neutrino follow-ups. His/her role in CTA will evolve during the three years of the fellowship, from preparation of the observations and the data analysis, to the analysis of the very first CTA data. As part of his/her duty as collaboration member, the candidate will perform observing shifts at the MAGIC telescopes. Being part of an international collaboration, the position demands high mobility and excellent skills in written and oral communication in English.
In parallel with the observational efforts, the candidate will work on the theoretical interpretation of the gamma-ray and neutrino data. For this part of the project, he/she will work in close interaction with the high-energy group at ICCUB, developing new numerical codes to simulate hadronic emission mechanisms in extragalactic sources. By comparing the predictions of numerical simulations to the gamma-ray and neutrino data, the candidate will constrain acceleration and radiation mechanisms in AGNs.
The candidate will present his/her results in international conferences and will take a leading role in writing refereed papers on behalf of the collaborations.
An excellent background in statistics, data analysis and computational physics is required.
- Data mining of Gaia releases: detection of Ultra Faint Dwarf Galaxies in the Galactic halo as probes for cosmological models[+]
Group Leader: Xavier Luri
http://icc.ub.edu/people/43Research Project Description
In this project we propose to exploit the Gaia data (ESA, 2 nd Release, 2018 and 3rd Release, 2021) to study a key process that drives the evolution of galaxies: the assemblage of the Galactic halo. The study will be focused on the detection of the “Ultra Faint Dwarf Galaxies” (UFDGs), objects with very low luminosity dominated by dark matter. Very few UFDGs have been discovered in the last decades although its detection is extremely relevant for the so-called “missing satellite problem”, a dramatic discrepancy between the observed number of galaxy satellites and the large number predicted by the state-of-the-art cosmological Λ Cold Dark Matter (CDM) models. Up to now, its detection has been limited to searches of over-densities in specific sky areas and using only photometric surveys. The Gaia catalogue has full sky coverage and, for the first time, extremely accurate stellar kinematics. It opens the possibility to design and apply data mining techniques for searching these structures in an n-dimensional space. Here we aim to obtain a new and unbiased census of UFDGs in the MW.
To detect UFDGs, the candidate will start by using the Wavelet Transform algorithms already designed by us (Antoja et al., 2015). She/he will use a tessellation method at the Mare Nostrum Supercomputers to run the algorithm using the 2 nd Gaia Data Release (about 1.3x10 9 stars), to derive a first list of new UFDGs we by the end of 2019. Next, new algorithms will be designed, developed and implemented in collaboration with the Workflows and Distributed Computing (WDC) group at the Barcelona Supercomputing Center (BSC). They will be applied both to real Gaia data and to high-resolution hydrodynamic N-body simulations of MW-like galaxies. In collaboration with the UCM (Madrid), and following our previous work (Roca-Fàbrega et al. 2016) we will use simulations obtained by using the newest versions of RAMSES code that include AGN feedback and SMBH formation (resolution lower than 50 pc).
Job Position Description
The PhD will be integrated in the Gaia group at the ICCUB under the group leader direction, combined with a co-direction from Dr. Rosa M Badia, leader of the WDC group at the BSC. This dual supervision will ensure the formation and support both in astrophysics and computing sciences. Dr. L.M. Sarro, from UNED, will bring the expertise on Bayesian parametric inference.
The candidate will participate in the regular Astrophysics, Cosmology training courses (including outreach and communication) at the ICCUB and the BSC. She/he will be responsible to write papers in referred journals. She/he will also join. The WDC group does research in parallel programming models, more specifically in task-based programming models for distributed computing platforms. The group has been deploying their research in the PyCOMPSs/COMPSs programming framework, and has been developing several data mining algorithms like clustering classification and machine learning algorithms.
The research experience and transferable skills gained will prepare the applicant not only for academy but also, if desired, for a research employment in other fields and even sectors. The applicant will strongly develop problem solving abilities, technical skills on big data, for sure useful in a broader employment market of the current times (e.g. working as a data scientist). We will provide to the candidate the skills needed to deal with the scientific exploitation of Gaia. She/he will be a member of the Gaia GREAT European network, in close connection with the Gaia Challenge DPAC-CU9 Working Group (DPAC: Gaia Data Processing and Analyzing Consortium, 400 European engineers and scientist working in Gaia). That will provide to the candidate training in a number of key areas including galactic and extragalactic astronomy and distributed computing, all of them focused on exploiting advanced database technologies to better facilitate the analysis and interpretation of Gaia's immense datasets.
- Black holes in stellar binary systems[+]
Group Leader: Marc Ribó
http://icc.ub.edu/people/57Research Project Description
High Mass X-ray Binaries (HMXBs) are binary systems typically composed of a massive B-type star with emission lines (a so-called Be star) and a neutron star (NS). A few years ago, we discovered the first Be star with a black hole (BH) companion, opening a new field of research in HMXBs. We are now studying a second candidate, which, however, has already revealed a different and very interesting behavior, suggesting that it is another type of binary system. Both types of systems are key to understand different evolutionary paths that lead to the formation of BH-NS systems, which are potential sources of gravitational waves when they merge.
The research project is focused on the discovery and multi-wavelength study of selected HMXBs, with a special emphasis on those containing Be stars with potential BH companions. These sources are potential emitters of gamma rays, as found in the case of the first Be/BH binary system. The project will require inspection and cross-correlation of catalogues, multi-wavelength observations in X-rays and radio, radial velocity studies at optical wavelengths and potential very-high-energy gamma-ray observations above 100 GeV with the MAGIC Cherenkov telescopes. The multi-wavelength observations will be interpreted to extract physical information of the geometries of the binary systems and the particle acceleration and emission/absorption processes taking place within them.
The research group has worldwide experts in both multi-wavelength observations (Marc Ribó, Josep M. Paredes) and theory (Valentí Bosch-Ramon) of galactic HMXBs. We have a high rate of success in the approval of observational proposals in competitive international observatories with time allocation committees (e.g., Chandra, XMM, VLA, etc.). We are also members of the MAGIC Collaboration and the LST Consortium that operates the first telescope of the Cherenkov Telescope Array (CTA) in La Palma.
Job Position Description
This job position is focused on the observational study of binary systems with potential black holes with high-energy emission up to at least X rays. The PhD student will get familiar with HMXBs in general, and with those containing Be stars in particular. He/she will be introduced in the physics of accreting compact objects and in the scenarios producing broadband non-thermal emission. He/she will participate in the scientific justification and technical preparation of observational proposals, as well as in the data reduction and analysis processes, which will conclude in the interpretation of the obtained results and subsequent publication in peer-review international refereed journals. He/she will become member of the MAGIC Collaboration and might have to conduct observational shifts with the MAGIC telescopes.
During the first year the PhD student will inspect and cross-correlate different multi-wavelength catalogues to search for new black hole candidates in binary systems and will propose observations to identify them. In parallel, he/she will analyze X-ray/radio observations already available and planned for the two Be binary systems identified. He/she will also contribute to understand the observed behavior at other wavelengths.
During the second year the student will analyze the obtained data from the observations of the black hole candidates proposed in the first year to assess or reject their possible black hole nature. In parallel, he/she will work to build up a physical model that is consistent with the available observational data, to gain knowledge on the physical processes happening inside the already known systems. He/she will also participate in the elaboration of new observational proposals to test the physical models.
During the third year of the PhD the student will analyze the observations planned during the second year to constrain the physical models of the HMXBs. He/she will summarize the work done to be defended as a PhD Thesis.
- Star formation at high redshift: clues from globular clusters[+]
Group Leader: Mark Gieles
http://icc.ub.edu/people/543Research Project Description
The stellar initial mass function (IMF) defines how many stars form as a function of their mass. The exact shape, and whether it is universal across space and time, affects a wide range of astrophysical phenomena, from star and galaxy formation to gravitational waves. Evidence for IMF variations was found in elliptical galaxies, based on both stellar kinematics and analyses of their stellar populations. This PhD project will test the “universal IMF hypothesis” by studying the mass function of globular clusters (GCs). These are old, dense stellar systems with a few million stars and were among the first baryonic structures to form in the early Universe. Their stellar populations contain therefore vital information about the IMF at high redshift. In this PhD project, you will develop and use a new method to infer the IMF from GCs. The present day MF of stars and stellar remnants — such as white dwarfs — is modelled by including the effects of dynamical evolution and stellar evolution. The model MF is then used to create dynamical mass models of GCs, which are compared to star count and kinematics from the Hubble Space Telescope (HST) and the ESA--‐Gaia mission. The kinematics of the visible stars is used to constrain the invisible dark stars and stellar remnants! Combining results of GCs with different metallicities, masses and ages enables a unique new test of the universality of the IMF in the earliest phases of galaxy formation. The super--‐visor (Mark Gieles) is an ICREA Research Professor at the ICCUB.
He is an expert in stellar dynamics, star formation and mass modelling of gravitational systems. He worked as a Royal Society University Research Fellow in the UK (Cambridge and Surrey) and is PI of a European Research Council (ERC) Starting Grant to study dark matter and black holes in the Milky Way. He is part of the “galaxy structure and evolution” group at the ICCUB, which actively participates in the ESA--‐ Gaia mission and related surveys.
Job Position Description
We will provide the candidate with the models for the stellar mass function, the dynamical models (LIMEPY) and the methods for fitting the models to the various observations. The supervisor has developed these models and has worked for several years on various observational applications (see related links). There may be the need to do numerical N--‐body simulations on dedicated Graphical Processing Units (GPUs) to generate mock data for doing tests of the dynamical models. Within the ICCUB there is a wealth of experience on scientific exploitation of data from the ESA--‐Gaia mission. This will provide training in a number of key areas on galactic and extragalactic astronomy; all of them focussing on exploiting advanced database technologies to better facilitate the analysis and interpretation of Gaia's immense datasets.
List of desirable skill sets for the candidates:
- 1. Basic concepts of stellar and Galactic dynamics;
- 2. Some experience with statistics: e.g. maximum likelihood methods;
- 3. Python programming language, Latex editing and Unix/Linux as operating system.
The candidate will benefit from all the regular Astrophysics, Cosmology and Data Mining training courses at the ICCUB and specific courses on scientific communication and outreach. She/he will be in charge of writing the corresponding papers in refereed journals (Astrophysical Journal, MNRAS, etc). The research experience and transferable skills gained will prepare the applicant not only for academia but also, if desired, for a research employment in other fields and even sectors. The applicant will develop problem--‐solving skills and working with big data, all of which are useful in a broad range of future employments.
- First science with the CTA Large Sized Telescope[+]
Group Leader: Marc Ribó
http://icc.ub.edu/people/57Research Project Description
During the last 15 years there has been a revolution in our understanding of the Universe at Very High Energy (VHE) gamma rays above 100 GeV. These photons are detected by ground-based Imaging Atmospheric Cherenkov Telescopes (IACTs) like HESS, MAGIC or VERITAS. A population of galactic sources has been unveiled close to the galactic plane, either by deep surveys or by dedicated observations of potential VHE emitters. Some of these sources have been studied in detail with the current generation of IACTs. However, the sensitivity of current experiments prevents the detection of short-term variability in most of these sources and does not allow us to obtain detailed spectra, limiting our understanding of the physical processes responsible of the VHE gamma-ray emission. In addition, a sensitivity improvement would allow us to discover and study in depth new types of sources.
The Cherenkov Telescope Array (CTA) is the next generation facility for the study of the Universe in VHE gamma rays. It will have a site in the northern hemisphere, located in La Palma (Canary Islands, Spain) and another one in the southern hemisphere, located in Paranal (Chile). The northern site is already being constructed, and the first Large Sized Telescope (LST-1) of CTA has been inaugurated in 2018 October. Commissioning will take place until 2019 October, and first science together with the nearby MAGIC telescopes could be conducted already at the end of 2019. The use of LST-1 together with MAGIC will provide an unprecedented sensitivity at energies around 100 GeV. Since at ICCUB we are both members of the MAGIC Collaboration and the LST Consortium, we will have immediate access to these data. This research project is focused on the first science with the CTA LST and MAGIC, with particular emphasis in the study of transient/variable galactic and extragalactic sources. The research group is led by Dr. M. Ribó (CTA), Dr. J.M. Paredes (MAGIC) and Dr. V. Bosch-Ramon (theory).
Job Position Description
This job position is aimed for a young physicist with a strong interest in high-energy astrophysics, with some previous knowledge on the topic. He/she will become a member of the CTA Consortium, the LST sub-consortium and the MAGIC Collaboration. He/she will analyze, for the first time, gamma-ray data of CTA telescopes. For this reason, knowledge in python programming is desirable. The student will work in an international collaboration of hundreds of people and might have to travel de the Canary Island of La Palma to conduct commissioning and/or observational shifts of the LST-1 and MAGIC telescopes.
During the first year the PhD student will help in the end of the commissioning and in the start of scientific observations with the LST-1 together with the MAGIC telescopes. This will provide him/her with a good knowledge of the data-reduction pipeline, in which development he/she might have to contribute.
During the second year it is foreseen that the student starts reducing scientific data of galactic and extragalactic transient sources such as microquasars, gamma-ray binaries, gamma-ray bursts or fast radio bursts. The student will participate in the whole process, from the scientific justification of observational proposals to the data reduction, interpretation and publication of the obtained results. There will be particular emphasis in studying detailed VHE spectra to check if they can be fitted with simple power laws or if there are high-energy cut-offs. Short timescale variability will also be studied in these sources. The final goal is to constrain the astrophysical scenarios behind the sources, to unveil if the emission processes are basically leptonic (such as synchrotron and Inverse Compton) or hadronic (pion production and decay).
During the third year of the PhD the student will propose new observations to be conducted with the 4 LSTs of CTA-North and will summarize the work done to be defended as a PhD Thesis.

Per processar-ho calen complexes algoritmes que necessiten la infraestructura distribuïda GRID Europea, seguint un model semblant a l'usat per l'Accelerador de Partícules LHC del CERN.
Un dels compromisos de l'ICCUB amb Virgo és la revisió del model computacional: com es gestionen les dades (enregistrament, transferència als diversos centres de càlcul, emmagatzemament i accés), com es processen (interfícies entre programadors/científics i infraestructures de càlcul), gestió de treballs i tasques, etc.
L'ICCUB ofereix una beca predoctoral per realitzar la tesi en aquestes tasques, contribuint així a un processament més eficient de les dades d'un dels majors projectes científics de la nostra era.
Les tasques a realitzar inclouran l'anàlisi del model computacional actual i la definició del nou model, l'adaptació d'infraestructures de computació (com p.ex. DIRAC) a Virgo, la definició i eventual implementació d'interfícies de dades i tasques amb el projecte LIGO d'Estats Units, etc.
Incorporació: Gener 2019.
Localitat: Barcelona (vora Palau Reial)
Jornada laboral: Completa
Requisits: Coneixements de programació en Python, C, Java, Matlab.
Coneixements de sistemes distribuïts de computació (tipus Grid Computing).
Es valoraran coneixements o experiència amb Workflow Management Systems com p.ex. DIRAC o similars, així com sistemes de High-Throughput Computing com p.ex. HTCondor.
Entorns de desenvolupament col·laboratiu (GIT o SVN).
Bon nivell d'anglès (llegit, escrit i conversa).
Capacitat de treball en equip.
Disponibilitat per viatjar (esporàdicament).
L'ICCUB està preocupat sobra la poca representació de les dones i les minories en àrees STEM, així doncs, encoratgem a les dones i a les minories a sol·licitar el lloc de treball.

The student will join the DESI collaboration and will have the opportunity to collaborate with other members of the ICCUB. The Dark Energy Spectroscopic Instrument, DESI (http://desi.lbl.gov/), is the cornerstone for the wider and most ambitious spectroscopic galaxy survey ever undertaken, with first light in 2019. It will measure 4 million Luminous Red Galaxies below redshift 1; 17 million of Emission Luminous Galaxies below redshift 1.6 and 2.4 million quasars between redshifts 0.9 and 3.5 among other programs. The large volume covered by DESI will allow sub-percent measurements on cosmological parameters, such the Baryon Acoustic Oscillation angular diameter distance and the Hubble parameter. Reaching such a level of precision is key to discriminate among different models of Dark Energy, to set constrains on the total amount of neutrino masses and to test GR as a theory of gravity at the largest regime ever explored, the size of the Universe.
Project: The student will work on developing methods to maximize the scientific return of DESI data by developing robust analyses techniques, by controlling and minimizing the impact of observational systematics, a necessary preliminary step for subsequently explore novel approaches and apply them to analyze the data provided by DESI in an optimal way. These techniques will be eventually applied by the student to the first science data produced by the DESI during its first years of observation. The bulk of the funding is provided by the prestigious “La Caixa” fellowship awarded to Dr. Héctor Gil-Marín who will move to ICCUB in the fall. The project will be supervised by Prof. Licia Verde (http://icc.ub.edu/~liciaverde/HomePage.html,liciaverde@icc.ub.edu), and Dr. Héctor Gil-Marín (http://ilp.upmc.fr/members/gilmarin.php, hector.gilmarin@lpnhe.in2p3.fr).

Research Project Description
FRBs are transient events of ms-duration whose nature and origin remain a mystery. Propagation through the intergalactic medium causes large time dispersion measurements, implying an extragalactic origin. The extremely short durations and the brightness temperatures associated suggest a coherent origin of the radiation. 17 bursts have been reported up to now and only one case is known to repeat suggesting different types of FRBs. Several models have been proposed to explain these events, based on the interactions of relativistic outflows with small perturbations (Romero et al. 2016) or invoking catastrophic events with massive reconnection events (Falcke & Rezzolla 2014; Liu et al. 2016).
In this PhD project, the candidate will develop these models and apply them to different scenarios such as: 1) Relativistic blobs ejected in the merger of a neutron star binary or magnetized black hole binaries; 2) Minijets in AGNs or blazars produced by dissipation of magnetic energy in a larger jet. The expected results of this study, such as the existence of possible counterparts at different wavelengths, can be put to the test through observations carried out by the hosting group (who has expertise in multiwavelength observations), giving to the candidate a unique opportunity to encompass in a single project all major steps of a scientific research from the theoretical development of a predictive model to prediction testing through the latest observational capabilities.
The group is composed of 15 researchers that combine observations and theory to understand the physics of astrophysical outflows at different scales, from stellar-mass systems to super massive BHs. The work on FRBs is focused on developing theoretical models (led by Prof. Romero, Univ. La Plata) and carrying out very long baseline interferometry (VLBI) observations to determine their exact location, and optical and VHE observations with MAGIC to explore the possible afterglow (led by Prof. Paredes, UB).
Job Position Description
The candidate must have background knowledge in relativistic astrophysics and, preferably, also in plasma physics. The job will require both analytical and numerical calculations of radiative processes in extreme physical conditions. Knowledge of general relativity is also desirable since the context of some potential sources involves gravitational radiation. The successful candidate is expected to strongly interact with the rest of the group through discussions, participation in seminars, and collaborations. Availability for traveling for periods of several weeks is indispensable, since strong interaction with the group led by Prof. Romero in Argentina is expected.
The duties of the job will include taking formal courses to complete the candidate’s academic formation in related subjects. The work offered will imply to fulfill all formal requirements for getting the PhD degree from the University of Barcelona, including writing the PhD Thesis within the period of the position.
- Luminosity Calibrations in the Gaia era [+]
Group Leader: Xavier Luri
Research Project Description
The upcoming second release of the Gaia data, scheduled for April 2018, will provide a large dataset (>1.5 billion objects) with precision full astrometry (positions, parallaxes and proper motions), complemented with radial velocities for a smaller subset (some hundreds of millions of objects). The precision and volume of these data will be further increased with the successive data releases (the third one scheduled for 2020).
The availability of such dataset will allow to revisit the problem of the calibration of luminosities for a wide variety of objects and to do so we need to take full advantage of both the large amount of data and its precision. For the first aspect we will apply the data mining and machine learning techniques that our team has been developing for the analysis of the Gaia data. These techniques will allow us to search and extract the relevant data from the Gaia archive, not relying on pre-existing lists of objects or selection criteria, minimizing biases and maximizing information. For the second aspect we will develop Bayesian models to fully exploit the extract the datasets for luminosity calibration; these models will integrate all the information available, implementing both physical models of the objects in question and models of the Gaia errors. They will also properly take into account sample censorships (both from the Gaia data itself and from the selection of subsets) to avoid any selection biases.The above described procedures will be applied to a key subset of cases that include:- Variable stars: Cepheids, RR-Lyrae
- Open clusters
- Globular clusters
- Red clump stars
- Derivation of photometric luminosity calibrationsz
- Apply statistical algorithms of data mining and machine learning to select and extract the relevant information from the Gaia releases.
- Develop Bayesian models for the luminosity calibration of the above mentioned types of objects from the Gaia data and apply them
- Develop a framework for an easy implementation of Bayesian models and its application to Gaia datasets
- Compare the results of the application of these models with other author's results to assess its reliability
- In the relevant cases, derive the consequences of the luminosity calibration results on the cosmological distance scale
- Write the corresponding papers in referred journals.
- Master in “Astrophysics, Particle Physics and Cosmology” of ICCUB or equivalent
- Expertise in Probability and Statistics, especially in Bayesian methods
- Programming skills
Additional cases (e.g. planetary nebula) may be included depending on the development of the work. In the relevant cases, consequences of the luminosity calibration results on the cosmological distance scale will be assessed.
Job Position Description
The person will join the Gaia group for the scientific exploitation of the Gaia data (mainly releases 2 & 3) for the determination of luminosity calibrations. The main responsibilities will be:
The desired skills for the candidate are:
- Radiative magnetohydrodynamics in powerful astrophysical outflows[+]
Group Leader: Valentí Bosch-Ramon
Research Project Description
The understanding of the astrophysical sources producing ultra-relativistic particles and energetic radiation requires the characterization of the underlying physics, which typically involve complex magnetized fluid dynamics, particle acceleration, and leptonic and hadronic radiation processes. This characterization has traditionally relied on models based on strong simplifying assumptions on the emitting region. The great improvement in observational instrumentation during the last decades has slowly pushed the field towards more complex theoretical models, and now it is time to work on fluid dynamics accounting for the production of ultra-relativistic particles and their radiation.
The project is focused on: (i) the development of extensions of existing relativistic magnetohydrodynamical codes to include the presence of very energetic particles and their emission; (ii) application of these tools to powerful galactic and extragalactic sources that feature interaction structures (binary systems, active galactic nucleus jets, etc.) that are expected to strongly radiate gamma rays and lower energy emission; (iii) to compare the accurate computational results with observations of these sources.
The research group is mostly oriented towards the theoretical modeling of very energetic sources in the Universe. The group leader, Dr. Valentí Bosch-Ramon, has been working for many years on galactic and extragalactic sources, and has a long experience and robust knowledge on the different techniques applied to model these objects, and interpreting related observations. In addition, the research group is embedded in a worldly recognized group led by Prof. Josep M. Paredes, with decades of experience in multi-wavelength observations from radio to gamma rays. It is thus the perfect context to plan observations to provide the theoretical research with observational feedback. Finally, the research will be carried out within a powerful net of experts from all over the world.
Job Position Description
The job position requires some modest experience with structured programming. At least basic understanding of special relativity and fluid dynamics is important. A working knowledge of English is also needed. It is also important to be open to attend conferences and carry out research stays abroad. Finally, what is mostly needed is motivation for solving interesting, complex but surmountable, physical problems, to work hard, and to learn team work as well as analytical and synthesis skills.
There is an important multi-disciplinary element in the job position, as it links basic physics disciplines with applied astrophysics and astronomy, i.e fluid dynamics in extreme conditions, modeling of radiation from astrophysical sources, and interpretation of observations and planning for prediction testing.
The doctorate schedule may be organized as follows:
- The doctoral fellow will develop extensions of powerful codes for relativistic magnetohydrodynamics. These extensions will take into account the generation, transport and energy evolution of ultra-relativistic particles in the simulated flow. This tool will permit sound and consistent modeling of powerful and complex sources, not well understood yet. In parallel, the fellow will become familiar with relativistic hydrodynamics, and non-thermal processes. This task would last for the first year.
- The fellow will apply the developed tools to hot topics in high-energy astrophysics, like gamma-ray production in galactic systems and in extragalactic jets. In parallel, the fellow will become familiar with the observations carried out to study these sources in the whole electromagnetic spectrum. This task would start towards the end of the first year.
- The fellow may take part in observational campaigns to observe the modelled sources, and participate in the proposal stage as well as in the interpretation of the results. This activity could take place during the second half of the doctoral period.
- Active galactic nuclei in merging galaxies: a theoretical approach [+]
Group Leader: Josep Maria Solanes Majúa
Research Project Description
Supermassive black holes (SMBH) have been detected in the centers of most nearby large galaxies. Galaxies today are not only the products of billions of years of hierarchical structure build up, but also billions of years of SMBH activity as active galactic nuclei (AGN) are thought to be the generic outcome of galaxy-galaxy mergers. In this context, detection of AGN pairs should be relatively common. Observationally, however, dual AGNs are scant, being just a few percent of all AGNs. In this PhD thesis, the candidate will investigate the triggering of AGN activity in merging galaxies via a suite of high-resolution hydrodynamical simulations. (S)He will follow the dynamics of the mergers and trace all processes related to star formation and the accretion of baryons onto the SMBHs, exploring AGN activity across a wide range of relevant conditions and testing when the two AGNs are simultaneously active and for how long, in an attempt to derive constraints for the dual AGN fraction detectable through imaging and spectroscopy.
The thesis is part of a research project that we are about to start at the ICCUB in close collaboration with researchers from the Instituto de Astrofísica de Andalucía (IAA) and the Instituto de Astrofísica de Canarias (IAC), a Severo Ochoa Center of Excellence. This joint effort, has been recently awarded funding by the Spanish Programa Estatal de Fomento de la Investigación Científica y Técnica de Excelencia over the period 2017-19. The ICCUB project aims using state-of-the-art computer simulations of galaxy interactions and mergers to capture much of the important physics of the processes involved on timescales affordable to study, thus providing a valid reference against which to compare observational data. In short, we are offering the opportunity to participate in a multidisciplinary endeavor that will allow students to acquire advanced academic training in diverse fields, from theoretical astrophysics to high-performance computing.
Job Position Description
The PhD candidate will have first to familiarize with the numerical tools and high-resolution collisionless simulations developed by our group, and then contribute to the implementation of the hydrodynamic modeling of the astrophysical dissipative processes related to the gas cooling, star formation, and feedback in galaxies that have a direct bearing on the feeding of their central SMBHs during a merger. (S)He will then perform and analyze a massive suite of numerical simulations of binary galaxy mergers, focusing on the separations and timescales for dual AGN activity. On a later stage, the candidate is also expected to contribute to the extension of the implementation of the evolutionary equations for baryons to forming galaxy groups, in which galaxies experience multiple collisions and mergers with other group companions, as well as strong interactions with the intragroup environment. The goal of this phase would be to build on the knowledge of the formation scenario of first-ranked objects in galaxy aggregations.
In order to succeed in his/her task, the candidate will have to deal with numerical simulations that include a dark matter, a stellar, and a multi-phase gaseous component in a fully self-consistent manner, and with sufficient resolution to minimize two-body heating, angular momentum loses, and alterations of the radiative cooling efficiency. In this context, our group has regular access to massive parallel supercomputers and, in particular, unrestricted access to the computing infrastructures of the IAA and IAC, each one of these with hundreds of CPUs available. Thanks to this, the PhD student will have sufficient computing power guaranteed at all times to carry out the numerical simulations required by the thesis.
The PhD candidate will be expected to carry part of his/her work at both the IAA and the IAC. We encourage individuals with good analytical/research skills and interested in acquiring a high degree of computer literacy to apply.
- Gaia Detection of Ultra Faint Dwarf Galaxies in the Galactic halo as probes for cosmological models [+]
Group Leader: Francesca Figueras
Research Project Description
Our Galaxy, the Milky Way, is our place in the Universe and our natural cosmological laboratory. Here we Propose to exploit the Gaia data (ESA,2nd Data Release Publication April 2018) to study a key astrophysical process that drive the evolution of our Galaxy and of galaxies in general, that is the assemblage of the Galactic halo. Few galaxies with very low luminosity and surface brightness, dominated by dark matter, called “Ultra Faint Dwarf Galaxies” (UFDGs), have been found during last decade in the halo of the Milky Way. Its detection is extremely relevant for the so-called “missing satellite problem”, the dramatic discrepancy between the observed number of galaxy satellites and the large number predicted by the state-of-the-art cosmological Λ Cold Dark Matter (CDM) simulations. Up to now, its detection is limited to searches of over-densities in the sky in photometric surveys and to the specific sky areas covered. The Gaia catalogue has full sky coverage and, for the first time, extremely accurate stellar kinematics. This data opens, for the first time, the possibility to design, test and apply clustering multivariate algorithms for searching these structures in an n-dimensional space. With this project we aim to obtain a new and unbiased census of UFDGs in the Milky Way halo to assess on solid grounds the discrepancy between the observations and predictions.
To detect UFDGs, the candidate will start by using the first algorithms already designed by us (see Antoja et al., 2015). In this case, a Wavelet Transforms methodology is used to identify significant peaks in the combined space of sky positions and proper motions. She/he will use a tessellation method at CSUC and Mare Nostrum Supercomputers to run the algorithm using this 2nd Gaia Data Release (more than 109 stars with position and velocities). Based on the list of new UFDGs found, we expect to assess the consequences for the missing satellite problem early in 2019. In a second step, new algorithms will be designed, developed and implemented in our GENIUS machine (spark strategy) both to real Gaia data and to high-resolution hydrodynamic N-body simulations of MW-like late type galaxies. Our simulations (Roca-Fàbrega et al., 2016) and others (e.g. Eagle) will be used for such purposes.
Job Position Description
We will provide to the candidate the skills needed to deal with the scientific exploitation of Gaia. She/he will be a member of the Gaia GREAT European network, in close connection with the Gaia Challenge DPAC-CU9 Working Group (DPAC: Gaia Data Processing and Analyzing Consortium, 400 European engineers and scientist working in Gaia). That will provide to the candidate training in a number of key areas on galactic and extragalactic astronomy, all them focused on exploiting advanced database technologies to better facilitate the analysis and interpretation of Gaia's immense datasets.
List of desirable skill sets for the candidates (we will form them in the field):
- Basic concepts on Astrometry from Space, Galactic Astronomy and Cosmology
- Probability and Statistics: Multivariate Data Analysis and advanced signal processing
- Programming languages (Python, C++ and R) and LaTex editor. Unix as computer operating system. Big data, distributed Computing and code optimization
The candidate will benefit from all the regular Astrophysics, Cosmology and Data Mining training courses at the ICCUB. Also from specific courses on scientific communication and outreach. She/he will be responsible to write the corresponding papers in referred journals (Astrophysical Journal, MNRAS, etc). The research experience and transferable skills gained will prepare the applicant not only for academy but also, if desired, for a research employment in other fields and even sectors. The applicant will strongly develop problem solving abilities, technical skills on big data, for sure useful in a broader employment market of the current times (e.g. working as a data scientist).
- Open Clusters Studies in the Gaia era [+]
Group Leader: Carme Jordi
Research Project Description
The Gaia group at the Institute of Cosmic Sciences (ICCUB) is involved in the Gaia space mission since its conceptual and design phases. The team consists of around 30 people (scientists and engineers) ranging from software development to data management, and its monitoring and scientific validation. The group was awarded the prize “Ciutat de Barcelona 2013”.
Gaia is a satellite by the European Space Agency, which main goal is to make the largest, most precise 3D map of our Galaxy by surveying a billion stars with an unprecedented precision (of the order of microarcsecond). This will allow the study of the formation and evolution of the Galaxy, the mapping of the dark matter, the comprehension of the stellar evolution, and so on. It is very well recognized that Gaia will impact all fields of astrophysics in the next decades.
Gaia Data Release 1, published on Sep 2016, contains results based on observations of the first 14 months of the operational phase. The mission will be operational for 5 years and due to the complexity of the data processing, the delivery of the data is foreseen in different stages. The second release, scheduled for April 2018, will provide positions and motions for more than one billion stars.
Open clusters (OCs) are crucial for the understanding the Galactic disc (where the stars born). While field stars suffer from many perturbations in their orbits due to the Galactic potential and migrate radially, OCs keep more stable orbits and are better tracers of the chemical enrichment. However, the lack of a large number of OCs analysed homogeneously hampers the investigations about chemical patterns and Galactocentric radial and vertical gradients, or an age-metallicity relation.
The project here aims to enlarge the sample of known OCs, the determination of their ages, total masses and Galactic positions (all from Gaia data) and their chemical abundances (from spectroscopic surveys like Gaia-ESO, OCCASO, and future WEAVE).
Job Position Description
The person will join the Gaia group for the scientific exploitation of the Gaia data (mainly the data release 2) in what concerns OCs studies and their impact on the understanding of star formation history in the Galactic disc and on the formation of the Galaxy as a whole.
The main responsibilities are:
- Develop statistical algorithms of data mining and machine learning to identify up-to-now unknown OCs, by identifying groups of common positions in the sky, common proper motions and common parallaxes based on Gaia data
- Apply stellar evolution theories to derive ages, and masses from the OCs member stars using the Gaia photometric data for a sample of OCs selected on the basis of their height above the Galactic plane, their Galactocentric position and their age
- Characterize the abundances of several chemical species from ground based acquired data (this is thanks to the Gaia team access to Gaia-ESO, OCCASO and future WEAVE high-resolution spectroscopic surveys), using synthesis and equivalent width methods already available to the team (iSpec & GALA)
- Determine the orbits of OCs joining kinematic information from Gaia and from spectroscopic observations, and check the stability of the orbits based on their properties and the mass of the cluster to deduce the possible radial migration
- Derive trends or gradients of abundances for every specie as a function of height above the Galactic plane, Galactocentric position and age
- Compare results with predictions from chemo-dynamical models of the Galactic disc evolution, in collaboration with the several groups with which the Gaia team has well established links and that are experts on this topic (Obs of Bologna, Inst. Astrophys. Canary, Institut für Astrophysik Potsdam, etc)
- Write the corresponding papers in referred journals.
The desired skills for the candidate are:
- Master in “Astrophysics, Particle Physics and Cosmology” of ICCUB or equivalent
- Understanding of Probability and Statistics
- Expertise in software
- Microlensing Gaia Alerts follow-up from Montsec Observatory [+]
Group Leader: Josep Manel Carrasco Martínez
Research Project Description
The Gaia group at the Institute of Cosmic Sciences (ICCUB) works in the space sector since the satellite Hipparcos (1989-1993). Gaia main goal is to make the largest, most precise 3D map of our Galaxy by surveying a billion stars with an unprecedented precision in position (of the order of microarcsecond) and motion. Their age and composition will also be obtained thanks to photometric measurements. Gaia will be able to clarify the structure, formation and evolution of our Galaxy, and will impact on every field of astrophysics (including stellar evolution, dark matter and general relativity). Our group has contributed since its inception in the concept of the Gaia mission and its design. In particular, our set of proposed photometric passbands was finally accepted as baseline for the mission in 2005. Some of these photometric passbands proposed for Gaia have been recently added also to the Javalambre Observatory in Teruel for their J-PAS/J-PLUS projects. Nowadays, our team is leading the development of the Gaia Archive, the initial processing and the photometric data treatment. Our team consists of around 30 scientists and engineers, ranging from software development to data management, as its monitoring and scientific validation. The group received the prize “Ciutat de Barcelona 2013”.
Gaia was launched in 2013 by the European Space Agency. Since then, a monitoring of the brightness of all sources in the sky is being driven. When some of these sources suddenly increase its brightness, an alert is triggered to the astronomical community to follow-up the evolution of this object. The first alert was issued in August 2014. Our team is also contributing to this Gaia Alerts follow-up programme using Joan Oró Telescope at Montsec Observatory (Sant Esteve de la Sarga, Lleida). With this programme we have been observing several supernovae explosions, variable stars and peculiar microlensing events in collaboration with several international teams.
Job Position Description
The candidate will continue with the Gaia Alerts follow-up programme from Montsec Observatory, studying in detail the microlensing events. Microlensing events are a powerful tool in finding invisible objects, including planets on Earth-like orbits, massive black holes or even Tidal Disruption Events:
- Microlensing planets in Gaia
- Stellar mass black holes from Gaia
- Hunt for Tidal Disruption Events
In order to detect a potential planet around the lens an intense follow-up observational campaign is necessary. In this project we propose to observe selected Gaia microlensing events with Observatory Montsec in order to detect a tiny deviation due to planet.
In order to recognise if the lens was a black hole it is necessary to obtain good coverage of the light curve to derive the parameters of the lens and to constrain potential black hole mass and distance. The project will require involvement in the observations of microlensing events with Observatory Montsec, data reductions and studies of individual events.
Supermassive black holes in centres of galaxies are often waken up by a star passing a bit too near. The accretion of the star produces a luminous blue flare, called Tidal Disruption Event. Gaia and other transient surveys detect candidates for central transients, however their multi-colour observations from the ground and space (Swift) are required to prove the transient is not just a supernova. In this project selected transients will be observed in detail from Observatory Montsec in order to find new examples of Tidal Disruption Events and measure masses of black holes in nuclei of galaxies.
Possible submission of observational proposals to other instruments to complement the photometric measurements from Joan Oró Telescope to fully understand the behaviour and nature of the alert can also be needed.
A candidate with formation in astronomy and physics is desired. Knowledge in telescopes and CCDs, stellar evolution and microlensing events is also appreciated.
- Stellar astrophysical parameters using J-PLUS photometry[+]
Group Leader: Josep Manel Carrasco Martínez

Some of these photometric passbands proposed for Gaia have been recently added to the Javalambre Observatory in Teruel for their J-PAS/J-PLUS projects.
The Javalambre-Photometric Local Universe Survey, J-PLUS, is a photometric sky survey of 8500 deg2 visible from Javalambre Observatory, using a set of 12 broad, intermediate and narrow band filters. The filter set was specifically aimed at the characterization of stars in our Galaxy. J-PLUS will create a unique catalogue of stars (to an unprecedented combination of depth and survey area), being able to fit the spectra of all the stars observed with their physical parameters (effective temperature, gravity and metallicity). Photometry with J-PLUS and kinematics and parallaxes from Gaia will allow the study of the structure of the galactic thick disk and halo.
Job Position Description
Role and responsibilities:
The role of the candidate is to exploit the knowledge of the team in the photometric passbands proposed for Gaia and currently installed in J-PLUS survey to derive the astrophysical parameters of the observed stars. This task will imply to establish a collaboration with Javalambre Observatory to retrieve observed photometry and to get familiar with the instrumentation installed in J-PLUS to understand the behaviour of the data. Once the instrumental effects are removed from the observations, the cleaned data need to be scientifically analysed and methods to classify and parameterise the stars in the sample (deriving their temperatures, gravities, metallicities, alpha abundances if possible, interstellar absorption, …) have to be established. The candidate will also be in charge of documenting all the work done and submit publications to astronomical refereed magazines (like Astronomy & Astrophysics and similar) and presentation of the results to some conferences and meetings.
Desired skills of the candidate:
A candidate with formation in astronomy and physics is desired. Knowledge in telescopes and CCD instrumentation, stellar physics and galaxies is also appreciated. The work will be done using Linux environment. Existing stellar parameterisation prototypes in the team are currently coded in Fortran. For the analysis of the J-PLUS images the candidate have to use reduction pipelines in IRAF, Sextractor and AstroPy (Python). The project documentation will be written in LaTeX. To establish the methodology to derive a parameterisation algorithm from photometry skills in statistical methods, chi-squared minimisation, bayesian methods and/or neural networks would be appreciated.
- Search for physics beyond the Standard Model in the LHCb experiment.[+]
Group Leader: Eugeni Graugés
Research Project Description
The experimental particle physics team in the ICCUB has contributed to heavy flavor experiments during the last 20 years. During this time, it has participated in the HERA-B experiment at DESY (Hamburg), the BaBar experiment at SLAC (Stanford) and, currently, the team is member of the LHCb collaboration at CERN (Geneva). Besides its contributions to the physics program of these experiments, the group has developed a significant expertise in the design, manufacturing and operation of custom electronics for the readout of photo-detectors.
A series of research grants, awarded mainly by the Spanish government in the calls from 1999-2014, funded the ICCUB participation in the LHCb experiment since the approval of the Technical Proposal by the LHCC (1998).
Concerning the responsibilities in the construction, installation and operation of the LHCb apparatus, the ICCUB contributions were focused in the Scintillator Pad Detector electronics of the calorimeter system. Work was performed in the design of the electronics and the integration in the general Experiment Control System (ECS). Maintenance tasks include the regular checks of detector setting parameters, replacement of aged electronic parts and improvement of the ECS software.
The ICCUB group has been involved in LHCb experiment physics analysis of radiative b-hadron decays where the signature is a photon in the final state. In this analysis, the ICCUB group is exploiting its expertise in the photon reconstruction carried out by the Calorimeter system in LHCb. As a result of all of the above participation, a total of 13 PhD thesis have been defended in the University of Barcelona since 2003.
LHCB responsibilities taken by ICCUB members have included: Computing Resource Manager (R. Graciani), Spain’s National Contact Person (E. Graugés, L. Garrido), Head of the LHCb National Computing Board (R. Graciani) and representative at the WLCG collaboration board (R. Graciani) and, Editorial Board (L. Garrido, E. Graugés).
Job Position Description
Operation, exploitation, and upgrade of the LHCb experiment at CERN: LHCb is designed to search for physics beyond the Standard Model (SM) of particle physics through precision measurements of CP violation and rare decays of heavy-flavored hadrons produced at the LHC. With the upgraded apparatus, the experiment will significantly increase its sensitivity with a higher discovery potential. At least two of the very few observations that point to the existence of physics beyond the SM (the baryon-antibaryon asymmetry and the neutrino oscillations) have a flavor physics nature. The search for new experimental insight in this field is therefore the next major milestone of the LHC experiments after the discovery of the Higgs boson. Direct searches provide the most direct path to the detection of new physics up to masses of the order of 1 TeV. Indirect searches at LHCb open the range up to 100 TeV through manifestations in quantum loops, with sizeable effects on some well-known physical observables, such as directly produced beauty and charmed particles. The proposed thesis is in the frame of B meson radiative decays. For instance, the analysis of the isospin asymmetry between the radiative B meson decays B0→ k*0(892)g and B+→ k*+(892)g , that only differ in the spectator quark, and therefore observables like the CP asymmetry and BR should not be significantly different (modulus the little mass difference). Nevetheless, this measurement can be sensitive to New Physics through a wide variety of mechanisms that produce isospin breaking effects (e.g., MSSM at large tanβ). The experimental challenge lies in the charged B+ meson decay, since a very precise measurement of the signal yield (~3%) is required in order to have competitive results with respect previous measurements carried out by the BaBar and Belle experiments. The combined sample of the LHC runs 1 and 2 together should provide enough statistics to make the most precise measurement of this asymmetry to date.
- Holography and Quark Matter [+]
Group Leader: David Mateos
Research Project Description
“Holography”, also known as AdS/CFT correspondence or gauge/string duality, is an equivalence between an ordinary Quantum Field Theory in flat space and a gravitational theory in a higher-dimensional, curved space. In the last decade it has had a significant impact on our understanding of the far-from-equilibrium dynamics of the Quark-Gluon Plasma (QGP) created in heavy-ion collision experiments. Through holography, the complicated quantum dynamics of the collision is mapped to an equivalent gravitational problem in terms of the classical dynamics of black holes in curved space.
The goal of this project is to extend this success to the low-temperature, high-quark-density region of the QCD phase diagram. Even the equilibrium properties (e.g. the equation of state) of the possible phases that may exist in this region are extremely difficult to study by conventional methods, let alone the non-equilibrium properties (e.g. transport coefficients). Yet, some of these quark-matter phases may be of direct experimental interest since they may be realized at the core of neutron stars. Moreover, following the recent detection of gravitational waves from the collision of two neutron stars, some of the properties of these phases may be soon experimentally accessible. The research of this project may prove indispensable in order to understand these experimental results.
Job Position Description
The candidate will begin by constructing holographic models of low-temperature, high-quark density phases of strongly coupled gauge theories. Particular attention will be played to phases that break the color gauge symmetry spontaneously (color superconducting phases) or that break translation invariance spontaneously (quark matter crystals). Then the properties of these phases will be systematically studied. First the equilibrium properties such as the equation of state, then the near-equilibrium properties such as the transport coefficients, and finally the far-from-equilibrium properties such as the response of the system to large perturbations.
The work in this project will involve a combination of theoretical and numerical techniques. On the theoretical side it will be highly interdisciplinary, ranging from gravitational physics to high-energy physics to condensed matter physics. On the numerical side it will involve programming in Mathematica and C.
- Holography and the QCD critical point [+]
Group Leader: David Mateos
Research Project Description
“Holography”, also known as AdS/CFT correspondence or gauge/string duality, is an equivalence between an ordinary Quantum Field Theory in flat space and a gravitational theory in a higher-dimensional, curved space. In the last decade it has had a significant impact on our understanding of the far-from-equilibrium dynamics of the Quark-Gluon Plasma (QGP) created in heavy-ion collision experiments. Through holography, the complicated quantum dynamics of the collision is mapped to an equivalent gravitational problem in terms of the classical dynamics of black holes in curved space.
The goal of this project is to extend this success to the region near the “QCD critical point”, a point in the QCD phase diagram where a line of first-order phase transitions ends. The discovery of this point is one of the main goals of the beam energy scan program at RHIC and of the future FAIR and NICA. The physics in these collision experiments will involve strong coupling and far-from-equilibrium dynamics. In the presence of these two features, holography is the only framework in which it is currently possible to perform first-principle calculations. The research of this project may therefore prove indispensable in order to understand the experimental results.
Job Position Description
The candidate will begin by constructing holographic models whose phase diagram includes a critical point. Then gravitational collisions in these models will be numerically simulated. By varying the parameters in these theoretical models, from the collision energy to the location of the critical point, the candidate will be able to gain unique qualitative insights ranging from the trajectories of the system in the temperature-baryon density plane to the fluctuations near the critical point.
The work in this project will involve a combination of theoretical and numerical techniques. On the theoretical side it will be highly interdisciplinary, ranging from gravitational physics to high-energy physics. On the numerical side it will involve programming in Mathematica and C.
- Star Formation in the Cosmological Context [+]
Group Leader: Paolo Padoan
Research Project Description
Star formation is a crucial process in Cosmology, to understand the re-ionization of the universe and the origin and evolution of galaxies. This PhD project tackle star formation by addressing fundamental questions of its role in the cosmological context: What physical processes control the distribution of stellar masses and the formation rate of stars and how do they change with cosmic time? What was the contribution of the very first stars to the re-ionization of the universe? Do globular clusters probe the early merging activities of mini halos in the standard cold-dark-matter model of the universe?
The research project consists of developing state-of-the-art computational models, focusing on two key contexts: 1) Magneto-hydrodynamic, cosmological simulations of the first dark-matter halos to collapse and form stars, to study the origin of Population III stars and their possible role in the re-ionization of the universe; 2) Simulations of the collision and merging of mini halos at high redshift, to investigate their possible role in the origin of globular clusters.
These are challenging multi-scale and multi-physics computational problems, requiring state-of-the-art massively parallel codes and large supercomputing allocations. The development of numerical codes is an important part of this project, which is carried out in close collaboration with the computational astrophysics group at the University of Copenhagen. The group in Barcelona will be composed by Prof. Padoan (group leader), Dr. Frimann, the PhD student, and long-term visitors from the University of Copenhagen. The main collaborators in Copenhagen will be Prof. Nordlund, Prof. Haugbølle. We have a proven track record in the field of computational astrophysics, leading the most challenging supercomputing applications in supersonic turbulence, star formation, solar physics, and plasma physics. We are regularly awarded some of the largest allocations in supercomputing facilities in the USA and Europe.
Job Position Description
The PhD student who aspires to lead this project will have a keen interest in fundamental astrophysical processes, a demonstrated aptitude for the development and adoption of numerical codes, and a steadfast determination to become a world leader in the field of star formation, with seminal and transformational contributions.
Though not a strict prerequisite, expertise in cosmology, hydrodynamics, plasma physics, turbulence theory and interstellar radiative processes is desirable. Good knowledge and experience with programming languages is required.
The student will lead the development of specific code modules, the set up of numerical simulations and the analysis of their results. She/he will also collaborate in the preparation of supercomputing proposals and will be the leading author of at least two publications per year in the second and third year of the project. The student will attend international conferences, workshops and focused schools on computational methods. She/he will spend part of the time at the Star and Planet Formation Center at the University of Copenhagen, to collaborate in the development of a new hydrodynamic code designed specifically for future exascale supercomputers.
Because of the multidisciplinary nature of this project, requiring expertise in cosmology, interstellar medium physics, star formation, magneto-hydrodynamics and computational methods, the student is expected to interact with different research groups within the Institute of Cosmos Sciences at the University of Barcelona and at other research centers abroad. Besides the collaborators in Copenhagen, the student will interact with researchers from the University of Helsinki (implementation of radiative transfer codes), Harvard University (physics of turbulence), University of Lund (origin of planetesimals), NASA Ames (modeling of dust evolution), Max Planck Institute of Munich (chemistry of protoplanetary disks).
- The Origin of Terrestrial Planets[+]
Group Leader: Paolo Padoan
Research Project Description
What sets the stage for the formation of rocky planets, possibly hosting conditions favorable to the emergence of life? Planets are the result of the evolution of dusty gaseous disks around young stars born within large clouds of cold interstellar gas containing thousands to millions of solar masses. To model ab initio the formation of protoplanetary disks we must develop a computational framework that captures the complex environment of star forming clouds, including the coupling of turbulence, magnetic fields, stellar radiation and gravity over a vast range of scales.
The project is composed of two parts: 1) Large-scale simulations of star-forming clouds, to achieve a realistic description of initial and boundary conditions for a large number of young stars and their circumstellar disks. 2) Simulations of dust evolution in protoplanetary disks, embedding billions of inertial particles, to study the transport and evolution of dust grains coupled with the gas dynamics self-consistently.
These are very challenging multi-scale and multi-physics computational problems, requiring state-of-the-art massively parallel codes and large supercomputing allocations. The development of numerical codes is thus an important part of this project, which is carried out in close collaboration with the computational astrophysics group at the University of Copenhagen. The group in Barcelona will be composed by Prof. Padoan (group leader), Prof. Estalella, Dr. Frimann, the PhD student, and long-term visitors from the University of Copenhagen. The main collaborators in Copenhagen will be Prof. Nordlund, Prof. Haugbølle and Prof. Jørgensen. We have a proven track record in the field of computational astrophysics, leading the most challenging supercomputing applications in supersonic turbulence, star formation, solar physics, and plasma physics. We are regularly awarded some of the largest allocations in supercomputing facilities in the USA (NASA High End Computing) and Europe (PRACE program).
