    Cosmology on small scales: the structure of (mostly) dark matter halos
    The standard model of cosmology -- the ``Lambda cold dark matter'' model -- is based on the idea that the dark matter is a collisionless elementary particle...

    Cusped Mass Models of Gravitational Lenses
    Recent observations of galaxy luminosity profiles and dark matter simulations find luminosity and mass distributions characterized by central cusps rather than...

    DALI, a pioneering dark matter telescope
    Axion detection would be one of the most exciting moments in the entire history of science. This hypothetical particle can simultaneously explain two...

    Dark bursts in the Swift era
    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...

    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...

    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...
