Transient sources in the high energy (HE, GeV) and very-high energy (VHE, TeV) gamma-ray domain have turned out to be excellent laboratories to test particle acceleration, emission, and absorption processes under extreme conditions, thanks to the multiple discoveries of transient phenomena at GeV and TeV energies reported during the last decade [1].

A leading candidate to explain the existence of dark matter in the Universe is the axion, which is detectable in experiments that use resonant cavities embedded in a strong magnetic field to turn an ambient axion of the dark matter halo of the Milky Way into a resonant photon. Superconducting qubits can be used to detect these photons without absorbing them, allowing for multiple detections of the same photon with minimal noise at mK temperatures, as demonstrated by Dixit et al. 2019.
GMV offers the possibility to participate on a remunerated project for the final master work (TFM). The number of satellites being launched into orbit has grown exponentially in the last years [1]. Even though they provide valuable information, they also create important challenges and concerns regarding their possible impact on the sky quality, their effect on astronomical observations or the space traffic management (see, e.g., [2] and [3]).
After the discovery of gravitational waves (GWs, Abbott et al. 2016), the LIGO-Virgo gravitational wave (GW) interferometers have detected 90 compact object coalescences of which the vast majority are binary black holes (BBH). A popular scenario for their origin is that these BBH form in dynamical interactions in dense stellar systems, such as globular clusters (GCs, e.g. Antonini et al. 2023).Â

The VLA Orion A Large Survey (VOLS) large project will perform the deepest survey at subarcsecond resolution of the Orion A molecular cloud with the Karl G. Jansky Very Large Array (PI: G. Busquet, see https://vols.fqa.ub.edu). The superb sensitivity of the VLA combined with the large field of view of VOLS (~1 deg x 0.5 deg) requires a new strategy to identify regions of line emission. The VOLS project includes the emission lines of OH and CH3OH masers, 18 Hydrogen Radio Recombination lines and the line thermal emission of HC5N and SO molecules.
cOrion A is the nearest star-forming complex containing a broad range of environments populated by protostars and Young Stellar Objects (YSOs) with different masses and evolutionary stages, representing a testbed for star formation theories. The VLA Orion A Large Survey (VOLS, PI: G. Busquet; see https://vols.fqa.ub.edu) large project has been granted with 306 hours of observing time with the Karl G. Jansky Very Large Array to perform the deepest survey at subarcsecond resolution of the Orion A molecular cloud.
The formation process of stellar cluster requires a high degree of cloud fragmentation. Both simulations and observations show that cloud fragmentation leading to the formation of stellar cluster is controlled by a complex interaction of gravitational instability, turbulence, magnetic fields, cloud rotation, and stellar feedback. The infrared dark cloud G14.225-0.506 hosts two hubs harbouring two deeply embedded protoclusters.
Photsat is the first astrophysics observatory being prepared by the Institut d'Estudis Espacials de Catalunya (IEEC) to be allocated in a cubesat mission to be launched in 2025-2026. The mission aims to survey the full sky during 2-3 years, obtaining photometric lightcurves for V<12-15 mag in several photometric filters, covering the optical and the ultraviolet range with a cadence of one datapoint every 2 days. This will complement the information of the transient sky at the bright end that other projects, as LSST, are not able to provide.
The large-scale structure of the universe commonly refers to the distribution of galaxies at scales above 100Mpc, spanning across a wide range of redshifts, 0<z<3.
