Indirect search for dark matter with Cherenkov telescopes

Abstract

Ground-based Cherenkov telescopes, also referred to as Imaging Atmospheric Cherenkov Telescopes, (IACTs) are array of large detectors, placed at moderate altitude, that catch the secondary induced Cherenkov emission produced in extensive atmospheric showers of particles generated by cosmic gamma rays. They are sensitive in the GeV-TeV region, and complete at high energy the MeV-GeV sensitivity of gamma-ray satellite experiments such as Fermi-LAT. In many of the possible realization of dark matter, this particle is stable because it is the lightest in some extension of the Standard Model. For this reason, indirect signatures from dark matter can come from annihilation events that take place in astrophysical environment. In this report, we briefly summarize the importance of gamma rays as probe for dark matter particle annihilations. We summarize current achievements and discuss future prospects
