    Dark matter in early-type galaxies: a SAURON view
    From galaxy formation theory we expect galaxies to be embedded in massive dark matter haloes. For spiral and dwarf galaxies this has indeed been observationally...

    Dark matter in galaxies
    The distribution of matter in galaxies of different luminosities and Hubble types, as inferred from observations, plays an important role in cosmology...

    Density distribution of the cosmological matter field
    The one-point probability distribution function (PDF) of the matter density field in the universe is a fundamental property that plays an essential role in...

    Descubierto el mecanismo que elimina la materia oscura de las galaxias
    La escasez de materia oscura en la galaxia NGC1052-DF4 ha desconcertado durante varios años a la comunidad astronómica. Ahora, un equipo de investigadores del...

    Detailed Theoretical Predictions for the Outskirts of Dark Matter Halos
    In the present work we describe the formalism necessary to derive the properties of dark matter halos beyond 2 virial radii using the spherical collapse model...

    Detection of satellite remnants in the Galactic halo with Gaia- III. Detection limits for ultrafaint dwarf galaxies
    We present a method to identify ultrafaint dwarf galaxies (UFDGs) candidates in the halo of the Milky Way using the future Gaia catalogue and we explore its...

    Detection of the Effect of Cosmological Large-Scale Structure on the Orientation of Galaxies
    Galaxies are not distributed randomly throughout space but are instead arranged in an intricate ``cosmic web'' of filaments and walls surrounding bubble-like...

    Determination of the anisotropy of elementary particles with the Alpha Magnetic Spectrometer on the International Space Station
    A measurement of the cosmic ray anisotropy on the arrival directions of elementary particles (electrons, positrons and protons) has been performed in galactic...
