Event Description 

The Fermi-LAT observation of a gamma-ray excess from the Galactic Center is an interesting hint of physics that we don't fully understand, which could possibly include Dark Matter. In order to investigate this possibility, one must understand how matter clusters around a super massive black hole. I will show the simplest way in which this can be modeled, assuming a slow evolution of the galactic dark matter halo, as well as how one can include all the nasty corrections due to General Relativity.
