Abstract

Neutrinos are probably the most interesting and intriguing particles in the Standard Model of Particle Physics. Although we have already advanced a lot of knowledge about neutrinos, there are still important unanswered questions: what are the absolute values of neutrino masses, and about the possible existence of sterile neutrinos. At the same time, Observational Cosmology has presented impressive results in recent years, due to the technological advance of astronomical surveys: greater resolution and precision of telescopes, greater depth and coverage in object maps, multiple probes for analysis, etc. This doctoral thesis presents the results of the first three years of observation of the Dark Energy Survey (DES) collaboration and how they have helped to better explain these questions about Neutrino Physics (AU)
