Abstract

Due to a large mass-to-light ratio and low astrophysical backgrounds, dwarf\nspheroidal galaxies (dSphs) are considered to be one of the most promising\ntargets for dark matter searches via gamma rays. The Fermi LAT Collaboration\nhas recently reported robust constraints on the dark matter annihilation cross\nsection from a combined analysis of 10 dSphs. These constraints have been\napplied to experimentally valid, super-symmetric particle models derived from a\nphenomenological scan of the Minimal Supersymmetric Standard Model (the pMSSM).\nAdditionally, the LAT Collaboration has searched for spatially extended,\nhard-spectrum gamma-ray sources lacking counterparts in other wavelengths,\nsince they may be associated with dark matter substructures predicted from\nsimulations.\n
