Fermi 130 GeV gamma-ray excess and dark matter annihilation in sub-haloes and in the Galactic centre
We analyze publicly available Fermi-LAT high-energy gamma-ray data and confirm the existence of clear spectral feature peaked at E=130GeV. Scanning over the Galaxy we identify several disconnected regions where the observed excess originates from. Our best optimized fit is obtained for the central r...
