    The dark and bright sides of massive early-type galaxies
    Massive early-type galaxies constitute an ideal test bed to probe our understanding of galaxy formation and evolution. Their high mass, spheroidal morphology...

    The Dark Energy Survey: Cosmology Results with ∼1500 New High-redshift Type Ia Supernovae Using the Full 5 yr Data Set
    We present cosmological constraints from the sample of Type Ia supernovae (SNe Ia) discovered and measured during the full 5 yr of the Dark Energy Survey (DES)...

    The dark side
    What's the dark matter made of? Do we have any idea of the kind of particle that should constitute ~85% of the matter content of the Universe? In this talk, I...

    The diverse density profiles of galaxy clusters with self-interacting dark matter plus baryons
    We present the first simulated galaxy clusters (M200 > 1014 M⊙) with both self-interacting dark matter (SIDM) and baryonic physics. They exhibit a greater...

    The effect of baryons on the inner density profiles of rich clusters
    We use the `Evolution and assembly of galaxies and their environments' (EAGLE) cosmological simulation to investigate the effect of baryons on the density...

    The effect of tides on the Fornax dwarf spheroidal galaxy
    Estimates of the mass distribution and dark-matter (DM) content of dwarf spheroidal galaxies (dSphs) are usually derived under the assumption that the effect of...

    The emergence of Low Surface Brightness Galaxies
    Low Surface Brightness galaxies are extremely dark matter dominated, faint objects hardly distinguishable from the night sky. In the last decade it has became...

    The ESO VISTA telescope and the VISTA Hemisphere Survey
    Survey operations with the VISTA telescope with it wide field near IR camera started in Feb 2010, following a science verification phase that started in Oct...
