Fermi bubbles around the M31 galaxy
We have searched for an extended high-energy gamma-ray emission around the nearby giant spiral Andromeda galaxy M31 using almost 7 years of Fermi LAT data at energies above 300 MeV. The presence of a diffuse gamma-ray halo with total photon flux 2:6±0:6×10−9 cm−2 s−1, corresponding to a luminosity (...
