High-energy tail of the Galactic Center gamma-ray excess
Observations by the Fermi-LAT have uncovered a bright, spherically symmetric excess surrounding the center of the Milky Way Galaxy. The spectrum of the γ-ray excess peaks sharply at an energy ∼2 GeV, exhibiting a hard spectrum at lower energies, and falls off quickly above an energy ∼5 GeV. The sp...
