    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 stellar halo in Local Group Hestia simulations. I. The in situ component and the effect of mergers
    Theory suggests that mergers play an important role in shaping galactic discs and stellar haloes, which was observationally confirmed in the Milky Way (MW)...
  • Publication
    The stellar halo in Local Group Hestia simulations. II. The accreted component
    Recent progress in understanding the assembly history of the Milky Way (MW) is driven by the tremendous amount of high-quality data delivered by Gaia (ESA)...

    The stellar halo in Local Group Hestia simulations. III. Chemical abundance relations for accreted and in situ stars
    Stellar chemical abundances and kinematics provide key information for recovering the assembly history of galaxies. In this work we explore the chemo-chrono...

    The Stellar Halo of the Spiral Galaxy NGC 1560
    We report on the detection of a stellar halo around NGC 1560, a 109 M ⊙ spiral galaxy member of the Maffei group. We obtained deep images in the r- and i-bands...
  • Publication
    The stellar host in blue compact dwarf galaxies. The need for a two-dimensional fit
    Context: The structural properties of the low surface brightness stellar host in blue compact dwarf galaxies are often studied by fitting r1/n models to the...

    The stellar host in star-forming low-mass galaxies: Evidence for two classes
    Context. The morphological evolution of star-forming galaxies provides important clues to understand their physical properties, as well as the triggering and...

    The Stellar Initial Mass Function at 0.9 < z < 1.5
    We explore the stellar initial mass function (IMF) of a sample of 49 massive quiescent galaxies (MQGs) at 0.9 z 1.5. We base our analysis on intermediate...

    The Stellar Kinematic Center and the True Galactic Nucleus of NGC 253
    We present the first sub-arcsecond resolution two-dimensional stellar kinematics and X-ray observations of the prototypical starburst galaxy NGC 253 which...
