The newest astronomical surveys, such as the Large Synoptic Survey Telescope (LSST) and the Dark Energy Spectroscopic Instrument (DESI), will measure the effect of dark energy on the expansion of the Universe. They will obtain photometric and optical spectra, respectively, for tens of millions or even billions of stars, galaxies and quasars, constructing the widest and deepest image of the Universe. These experiments will help us to better understand the origin of the accelerating expansion, to test possible models of modified gravity and to impose new constraints on the parameters of neutrinos. Therefore, our main goals and our tasks within these experiments are to analyze different models from Neutrino Physics - such as mass generation mechanisms, normal or inverted mass ordering, and sterile neutrinos scenarios - and to confront them with simulations and cosmological data of these surveys using multiple probes: baryon acoustic oscillations, redshift space distortion, and 2-point correlation functions of galaxy clustering and galaxy lensing; along with external data, e.g. CMB and supernovae.
