Description
Dwarf spheroidal galaxies are ideal candidates for indirect dark matter searches. They are dark matter dominated and usually contain no intrinsic astrophysical sources of gamma ray emission. In order to accurately predict the dark matter annihilation signal from dwarf spheroidal galaxies, it is crucial to correctly model the phase space distribution of dark matter in them. Hydrodynamical simulations of galaxy formation provide important information on the dark matter distribution in dwarf spheroidal analogues. I will present the dark matter density profile and velocity distribution of Milky Way’s dwarf spheroidal galaxies extracted from state-of-the-art hydrodynamical simulations, with a focus on the Sagittarius dwarf spheroidal galaxy. I will also discuss the implications for indirect dark matter searches from dwarf spheroidal galaxies for velocity-dependent dark matter annihilation models.
