Astrophysical: Dark matter

  • Publication
    The slow evolution of dark matter halos from cusp to core naturally produces extended stellar core-like distributions
    Motivated by the observation of extended stellar cores in dark matter (DM)-dominated dwarf galaxies, this study investigates a simple mechanism by which stellar...

    The spherical collapse model with shell-crossing
    In this work, we study the formation and evolution of dark matter haloes by means of the spherical infalling model with shell-crossing. We present a framework...

    The SPLASH Survey: A Spectroscopic Analysis of the Metal-Poor, Low-Luminosity M31 dSph Satellite Andromeda X
    Andromeda X (And X) is a newly discovered low-luminosity M31 dwarf spheroidal galaxy (dSph) found by Zucker et al. in the Sloan Digital Sky Survey (SDSS; York...

    The Standard Cosmological Model
    This is the first talk of a series of four aimed to discuss about Cosmology. Here, I will review the basic concepts of the standard cosmological model, which...

    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...

    The three hundred project: mapping the matter distribution in galaxy clusters via deep learning from multiview simulated observations
    A galaxy cluster as the most massive gravitationally bound object in the Universe, is dominated by dark matter, which unfortunately can only be investigated...

    The Wendelstein Calar Alto Pixellensing Project (WeCAPP): First MACHO Candidates
    We report the detection of the first two microlensing candidates from the Wendelstein Calar Alto Pixellensing Project (WeCAPP). Both are detected with a high...

    The Wendelstein Calar Alto Pixellensing Project (WeCAPP): the M 31 variable star catalogue
    In this paper we present the WeCAPP catalogue of variable stars found in the bulge of M 31. Observations in the WeCAPP microlensing survey (optical R and I...
