Title: Confronting various dark matter scenarios with dwarf spheroidal gamma-ray observations
Abstract: Dwarf spheroidal galaxies are promising targets for the indirect detection of dark matter through gamma-ray emission due to their proximity, lack of astrophysical backgrounds and high dark matter density. They are often used to place restrictive bounds on the dark matter annihilation cross section. In this report, we analyze six years of Fermi-LAT gamma-ray data from Dwarf Spheroidal galaxies that are satellites of the Milky Way, and constrain the parameter space that explain the Fermi-LAT Galactic center gamma-ray emission in 4 body final states, neutralino dark matter annihilation cross-section, and decaying dark matter lifetime for several decay channels.
