    The Impact of Dwarf-Dwarf Galaxy Tidal Interactions
    Two competing effects appear to govern galaxy multiplicity (pairs orgroups) at low masses: while associations of low-mass haloes are naturally expected in a...

    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. 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...
