Unraveling the origins of the Galactic Center excess gamma rays
Abstract: The properties of the dark matter that dominates the matter budget of the Universe remains unknown. The center of the Milky Way galaxy provides a promising target to search for signatures of dark matter self-annihilation or decay into Standard Model particles. However, astrophysical backgrounds are complex and must be modeled with care. I will discuss on-going studies of the so-called Galactic Center Excess (GCE) discovered in Fermi-LAT data, focusing on recent developments on modeling the astrophysical backgrounds and their implications for competing hypotheses for the origin of the excess. I will also discuss future directions for unraveling the nature of this intriguing excess.
