Recent observations of galaxy luminosity profiles and dark matter simulations find luminosity and mass distributions characterized by central cusps rather than...
Axion detection would be one of the most exciting moments in the entire history of science. This hypothetical particle can simultaneously explain two...
The nature of the dark bursts is still not fully understood. Here, we report on some of our recent studies on Swift dark bursts. Thereby, we pay particular...
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...
Dark Energy Survey Year 3 results: galaxy-halo connection from galaxy-galaxy lensing
Galaxy-galaxy lensing is a powerful probe of the connection between galaxies and their host dark matter haloes, which is important both for galaxy evolution and...
Dark halo structure in the Carina dwarf spheroidal galaxy: joint analysis of multiple stellar components
Photometric and spectroscopic observations of the Carina dSph revealed that this galaxy contains two dominant stellar populations of different age and...
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...
