I will discuss constraints on dark matter annihilating or decaying in the Milky Way Halo from observations of the diffuse gamma-ray emission with the Fermi Large Area Telescope.
A novel approach is developed to take into account the astrophysical foregrounds, with the use of the GALPROP code to model the foreground astrophysical diffuse emission and a profile likelihood formalism to...

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 detailed origin of the diffuse gamma-ray background is still unknown. However, the contribution of unresolved sources is expected to induce small-scale anisotropies in this emission, which may provide a way to identify and constrain the properties of its contributors. Recent studies have predicted the contributions to the angular power spectrum (APS) from extragalactic and galactic dark...

In my talk I will explore the possibility that the dark matter is related to the origin of neutrino masses. In fact, neutrino masses could arise from spontaneous breaking of ungauged lepton number and the resulting Goldstone boson, the majoron, may pick up a mass due to gravity and play the role of dark matter. I will first examine the cosmological constraints on the majoron density and...
