    The Life Cycle of Matter in the Magellanic Clouds: Insights from Spitzer and Herschel
    The life cycle of baryonic matter in a galaxy is driven by the exchange of material between the interstellar medium (ISM) and stars, which are the agents of...

    The metal content of GR 8 and Sextans B
    Ionic abundances for two irregular dwarf galaxies belonging to the Local Group, GR 8 and Sextans B, are presented. The oxygen abundances have been found to be 0...

    The PAndAS View of the Andromeda Satellite System. III. Dwarf Galaxy Detection Limits
    We determine the detection limits of the search for dwarf galaxies in the Pan-Andromeda Archaeological Survey (PAndAS) using the algorithm developed by the...

    The PAndAS View of the Andromeda Satellite System. IV. Global Properties
    We build a statistical framework to infer the global properties of the satellite system of the Andromeda galaxy (M31) from the properties of individual dwarf...

    The Second Data Release of the Survey of the MAgellanic Stellar History (SMASH)
    The Large and Small Magellanic Clouds (LMC and SMC) are the largest satellite galaxies of the Milky Way and close enough to allow for a detailed exploration of...

    The Star Formation & Chemical Evolution timescales of two nearby dwarf spheroidal galaxies
    We present the detailed Star Formation History of the nearby Sculptor and Fornax dwarf spheroidal galaxies, from wide-field photometry of resolved stars, going...

    The star formation history of different types of dwarf galaxies
    We are going to present a new code to derive the SFH of a complex stellar population system, like a galaxy. This code has been used to obtain the SFH of six...

    The Star Formation History of Eridanus II: On the Role of Supernova Feedback in the Quenching of Ultrafaint Dwarf Galaxies
    Eridanus II (Eri II) is an ultrafaint dwarf (UFD) galaxy (M V = -7.1) located at a distance close to the Milky Way virial radius. Early shallow color-magnitude...

    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...
