Title: INDIRECT DETECTION OF DARK MATTER

Abstract:

Dark Matter, an invisible and elusive substance originally proposed by Zwicky to explain the mass to light ratio of galaxies and galaxy clusters, still evades revealing its true identity. Many Dark Matter candidates have been proposed, spanning many orders of magnitude in mass. I will discuss prospects of indirectly detecting Dark Matter through either self-annihilation or decay products, and, present corresponding general upper bounds on total self-annihilation cross section or lifetime. As an example, I will focus on two particular scenarios: Dark Matter models associated with 0.511 MeV positron annihilation line from the center of our Galaxy and sterile neutrinos as Warm Dark Matter candidates.
