Description
Today there exists a strong evidence to believe that most of the matter in our Universe is made of dark matter (DM). In the last years, a huge effort has been focused on understanding its nature as well as its detection. The indirect detection of DM, namely, the detection of the annihilation or decay products of DM particles, is a useful and important tool. First, in this talk I will focus on the contribution to the diffuse neutrino and gamma-ray background from DM annihilations in halos at several redshifts and the role of subhalos on such searches. Finally, I will briefly present the guidelines for a project that will be carried out with Dr. Carlos Arguelles and other members of ICRANet and UNLP-CONICET, about the emission in the X-ray background that would be produced by decay of sterile neutrino DM from the galactic center. This study will be performed assuming the Ruffini-Arguelles-Rueda (RAR) model, for the distribution of DM in galaxies.
