Neutrino physics: status and quests for the future
Abstract: Neutrino physics has entered the precision era. Nevertheless many questions still remain without an answer. We know that the SM cannot be the ultimate theory, since a so-called “elusive” sector is completely missing: neutrinos are not properly included since we cannot describe their mass. Moroever, the nature, Dirac or Majorana, of the three light active neutrinos nuj (j = 1,2,3) with definite mass mj is unknown. I will review unknown properties of neutrinos and how possibly detect some of them. In particular I will define a theoretical framework and deduce the conditions under which multi-messenger astronomy can constrain neutrino masses and unveil their ordering. The framework uses time differences between the arrival of neutrinos and the other two light messengers, i.e. light and gravitational waves, emitted by astrophysical catastrophes.

Cosmology and the Dark Energy Survey
Abstract: The Dark Energy Survey (DES) is a 5000 square degree survey targeting dark matter and dark energy science. This year sees the release of the first science results from the DES collaboration using data taken during science verification. I plan to present these new results, which include dark matter maps, cosmology constraints and new discoveries such as the new strong lens systems being found. I will also give an update on the progress of the main science survey, which is still ongoing.
