Description
Weakly interacting massive particles (WIMPs) produced through thermal freeze-out are a highly motivated dark matter (DM) candidate. Since WIMP DM acquired its relic abundance through self-annihilations, such particles must continue to annihilate to Standard Model final states and would produce observable signatures in astrophysical gamma-ray searches. In this work, we perform a search for WIMP annihilation in Milky Way dwarf galaxies with gamma-ray data from the Fermi Large Area Telescope. In particular, we improve upon previous searches by inferring astrophysical $J$-factors for dwarf galaxies using the SatGen semi-analytic satellite galaxy generator.
