Dark matter annihilation and the Galactic Centre Excess
We compare the surface brightness profile and morphology of the Galactic Centre Excess (GCE) identified in wide-angle γ-ray maps from the Fermi-Large Area...
Dark matter content of ETGs and its relation to the local density of galaxies
We study the behaviour of the dynamical and stellar mass inside the effective radius as function of local density for early-type galaxies (ETGs). We use several...
Dark Matter Decay and Annihilation in the Local Universe: Clues from Fermi
We present all-sky simulated Fermi maps of γ-rays from dark matter (DM) decay and annihilation in the local universe. The DM distribution is obtained from a...
Dark matter halo concentrations in the Wilkinson Microwave Anisotropy Probe year 5 cosmology
We use a combination of three large N-body simulations to investigate the dependence of dark matter halo concentrations on halo mass and redshift in the...
