Description
High-energy gamma rays are one of the most promising tools to constrain or reveal the nature of Dark Matter (DM), in particular the Weakly Interacting Massive Particles (WIMP) models. During the almost eight years of the Fermi satellite mission, the data from its Large Area Telescope (LAT) were used to set constraints on the WIMP annihilation cross section which cut well into the theoretically-motivated region of parameter space for WIMP masses below 100 GeV. At the same time, the Cherenkov Telescope Array (CTA) is well into its prototyping phase and will soon offer a chance to probe a complementary parameter space of heavier dark matter (from O(200 GeV) up to several tens of TeV ), with unprecedented sensitivity.
In this talk I will describe methods used to search for evidence of dark matter with the LAT, and review the status of the searches. I will discuss projections of the expected sensitivities with continued LAT data taking, together with the latest sensitivity predictions on the various targets with CTA.
