Fermi-LAT Observations of Gamma-Ray Emission Towards the Outer Halo of M31
Chris Karwin, Simona Murgia, Sheldon Campbell +1
The Andromeda Galaxy is the closest spiral galaxy to us and has been the subject of numerous studies. It harbors a massive dark matter (DM) halo which may span up to ~600 kpc acros…

The Galactic Isotropic -ray Background and Implications for Dark Matter
Sheldon S. Campbell, Anna Kwa, Manoj Kaplinghat
We present an analysis of the radial angular profile of the galacto-isotropic (GI) -ray flux--the statistically uniform flux in circular annuli about the Galactic center. Two di…
Combined Flux and Anisotropy Searches Improve Sensitivity to Gamma Rays from Dark Matter
Sheldon S. Campbell, John F. Beacom
Searches for dark matter annihilation signals in the diffuse gamma-ray background are promising. We present the first comprehensive study utilizing both flux and anisotropy, using…
Effects of P-wave Annihilation on the Angular Power Spectrum of Extragalactic Gamma-rays from Dark Matter Annihilation
Sheldon Campbell, Bhaskar Dutta
We present a formalism for estimating the angular power spectrum of extragalactic gamma-rays produced by dark matter annihilating with any general velocity-dependent cross section.…
