New limits on the dark matter lifetime from dwarf spheroidal galaxies using Fermi-LAT
New limits on the dark matter lifetime from dwarf spheroidal galaxies using Fermi-LAT
Dwarf spheroidal galaxies (dSphs) 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 paper, we analyze …
