Cosmology with large-scale structure

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. This is currently one of the wealthiest sources of cosmological information in modern cosmology exploited by surveys such as the Dark Energy Spectroscopic Instrument (DESI, https://www.desi.lbl.gov/) or the EUCLID mission (https://sci.esa.int/web/euclid). In this TFM the student will be able to choose one of the hot-topic in cosmology today: 1)  studying and exploiting the techniques to measure the expansion history of the universe and the effect of Dark Energy through Baryon Acoustic Oscillations; 2) understanding the theory of gravity that rules at inter-galactic scales through Redshift Space Distortions; 3) studying the impact of neutrinos on the distribution of matter and galaxies at large scales; 4) employing higher-order statistics to measure gravitational and/or primordial non-Gaussianities and study their connection to the inflationary era;  just as a few examples. The student will have the opportunity to work with several members of the cosmology unit at the ICCUB and use real data from the DESI survey, in which the cosmology team is highly involved.
