Abstract
Studies of data from the Fermi Gamma-Ray Space Telescope have revealed bright gamma-ray emission from the central regions of our galaxy, with a spatial and spectral profile consistent with annihilating dark matter. I will discuss the properties of this emission, and then present a new analysis that suggests that rather than originating from dark matter, this signal may reveal a surprising new population of gamma-ray point sources in the heart of the Milky Way.
