Title: Dark Matter Annihilation and the Galactic Center Gamma-Ray Excess

Abstract: The Galactic Center Gamma-Ray Excess has a spectrum, angular distribution, and overall intensity that are in remarkable agreement with that expected from annihilating dark matter particles in the form of a ∼ 50 GeV thermal relic. Alternatively, it has been suggested that this signal might be produced by a large number of centrally located millisecond pulsars. The fact that no such pulsar population has been detected implies that these sources must be very faint and very numerous. In light of these results, it now appears significantly more likely that the Galactic Center Gamma-Ray Excess is produced by annihilating dark matter.
