On The Origin Of The Gamma Rays From The Galactic Center

摘要: The region surrounding the center of Milky Way is both astrophysically rich and complex, predicted to contain very high densities dark matter. Utilizing three years data from Fermi Gamma Ray Space Telescope (and recently available Pass 7 ultraclean event class), we study morphology spectrum gamma ray emission this find evidence a spatially extended component which peaks at energies between 300 MeV 10 GeV. We compare our results those reported by other groups good agreement. could potentially originate either annihilations matter particles in inner galaxy, or collisions energy protons that are accelerated Way's supermassive black hole with gas. If interpreted as annihilation products, favors mass range 7-12 GeV (if annihilating dominantly leptons) 25-45 hadronic final states). intensity corresponds cross section consistent required generate observed cosmological abundance early universe (sigma v ~ 3 x 10^-26 cm^3/s). also present conservative limits on least stringent derived observations.
