Description
Dwarf spheroidal galaxies have a large mass to light ratio and low astrophysical
background, and are therefore considered one of the most promising targets for dark
matter searches in the gamma-ray band. The Fermi-LAT sensitivity to gamma-ray sources
can be improved through the use of a combined likelihood analysis, which in the event
of a null detection, yields enhanced constraints on dark matter parameter space. From
a combined analysis of the Fermi-LAT data for 10 dwarf spheroidal galaxies, we derive
robust constraints on the dark matter annihilation cross section for multiple
channels accounting for astrophysical uncertainties.
