Description

We calculate the diffuse gamma-ray emission due to the population of misaligned AGN (MAGN) unresolved by the Large Area Telescope (LAT) on the Fermi Gamma-ray Space Telescope. We demonstrate that the MAGN can contribute from 10% up to nearly the entire measured Isotropic Gamma-Ray Background (IGRB), with a theoretical uncertainty on the flux of almost an order of magnitude. We also evaluate the room left to galactic dark matter at high latitudes, by taking into account the new result on the MAGN contribution to the IGRB, together with the other significant galactic and extragalactic components.
