    The statistics of voids as a tool to constrain cosmological parameters: σ8 and Γ
    We present a general analytical formalism to calculate accurately several statistics related to underdense regions in the Universe. The statistics are computed...

    The Stellar Distribution in Ultrafaint Dwarf Galaxies Suggests Deviations from the Collisionless Cold Dark Matter Paradigm
    Unraveling the nature of dark matter (DM) stands as a primary objective in modern physics. Here we present evidence suggesting deviations from the collisionless...
