摘要: We construct empirical models of the diffuse gamma-ray background toward Galactic Center. Including all known point sources and a template emission associated with interactions cosmic rays molecular gas, we show that extended observed previously in Fermi Large Area Telescope data Center is detected at high significance for permutations model components. However, find fluxes spectra our change significantly depending on model. In particular, spectrum central Sgr A* source less steep than previous works recovered has large systematic uncertainties, especially lower energies. If interpreted to be due dark matter annihilation, annihilation into pure b-quark τ-lepton channels statistically equivalent goodness fits. case channel, mass 39.4(+3.7-2.9stat)(±7.9sys)GeV, while τ+τ - channel an estimated 9.43(+0.63-0.52stat)(±1.2sys)GeV. Alternatively, if astrophysical origin such as unresolved millisecond pulsars, obtain strong bounds although uncertainties dependence are significant. © 2014 American Physical Society.
