Description
The Galactic center (GC) is one of the most important regions to search for a gamma-ray signal from a possible annihilation of dark matter due to its proximity and high dark matter density. In the past years, several groups have reported an excess of gamma rays in the Fermi-LAT data with an approximately spherical morphology around the GC. In this talk I will review the current observational status of the excess, the difficulties in the gamma-ray analysis near the GC, and possible interpretations, such as an additional source of cosmic rays, a population of millisecond pulsars, and dark matter annihilation. I will discuss how one can distinguish these possibilities with future observations.
