The Galactic Center GeV Gamma-ray Excess: Have We Started to See Dark Matter?
abstract
Recent claims of an excess of gamma rays from the Galactic center have grown in statistical significance over the last few years. In this talk, I’ll provide a (fairly optimistic) summary of the observational and phenomenological work relating to the Galactic center GeV excess. This will necessitate an up-to-date discussion of the claims in the literature, and will also include discussion of some particle physics models that can provide a basis for the signal. I’ll go on to discuss ideas for new techniques that might help push us toward a deeper understanding of the signal and its phenomenology.
