    Constraints on Ultra-Light Dark Matter from Galactic Rotation Curves
    Bosonic ultra-light dark matter (ULDM) in the mass range m ~ $10^{-22} - 10^{-21} \rm eV$ has been invoked as a motivated candidate with new input for the small...

    Cosmic Microwave Background observations
    In the first part of this talk I will present a historical review of the CMB observations, one of the most powerful cosmological probes. Following the first...

    Cosmological giants and elves: galaxy formation and the small scale of cold dark matter
    I will review the status of our understanding of galaxy formation in the prevailing cold dark matter paradigm. After reviewing the successes and failures of the...

    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...
