Description
Our Galaxy resides in the center of a vast "Halo" of Dark Matter (DM). This concentra-
tion produces, in many viable particle physics models, an indirect Weakly Interacting Massive Particle (WIMP)
annihilation signal that peaks in the Fermi-LAT's energy range. Our knowledge
of the diffuse background is essential to placing reasonable limits on the DM mass and
cross-section. We incorporate a systematic variation of the GALPROP galactic diffuse background
model, constrained by current cosmic-ray measurements, into a profile likelihood analysis
and present upper limits on the DM annihilation cross-section using the Fermi-LAT data.
