Galactic Center GeV Excess
The Galactic Center GeV Excess is an unexpected surplus of gamma-ray radiation in the center of the Milky Way galaxy that is unexplained by direct observation., this excessive gamma-ray radiation is not well understood by astronomers. However, astronomers have suggested that self-annihilating dark matter may be a dominant contributor to the GCE, based on analysis using non-Poissonian template fitting statistical methods, wavelet methods, and studies by other astronomers may support this idea. Other hypotheses include ties to an unseen population of millisecond pulsars or young pulsars, burst events, the stellar population of the galactic bulge, or the Milky Way's central supermassive black hole.
Two percent of the gamma ray radiation in a 30° radius circle around the galactic center is attributed to the GCE. While some controversially argue that it might be radiation from dark matter or another exotic explanation, some still believe that conventional objects such as pulsars could explain the GCE.
