Constraints on Dark Matter and Supersymmetry from LAT Observations of
  Dwarf Galaxies
  Due to a large mass-to-light ratio and low astrophysical backgrounds, dwarf
spheroidal galaxies (dSphs) are considered to be one of the most promising
targets for dark matter searches via gamma rays. The Fermi LAT Collaboration
has recently reported robust constraints on the dark matter annihilation cross
section from a combined analysis of 10 dSphs. These constraints have been
applied to experimentally valid, super-symmetric particle models derived from a
phenomenological scan of the Minimal Supersymmetric Standard Model (the pMSSM).
Additionally, the LAT Collaboration has searched for spatially extended,
hard-spectrum gamma-ray sources lacking counterparts in other wavelengths,
since they may be associated with dark matter substructures predicted from
simulations.
