Dark Energy and Cosmic Sound
I will discuss how the acoustic oscillations that propagate in the photon-baryon fluid during the first million years of the Universe provide a robust method...

PublicationDark matter annihilation and the Galactic Centre ExcessWe 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...

PublicationDark matter content of ETGs and its relation to the local density of galaxiesWe 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...

PublicationDark Matter Decay and Annihilation in the Local Universe: Clues from FermiWe 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...
