    The emergence of Low Surface Brightness Galaxies
    Low Surface Brightness galaxies are extremely dark matter dominated, faint objects hardly distinguishable from the night sky. In the last decade it has became...

    The Fast X-Ray Transient XRT 210423 and Its Host Galaxy
    Fast X-ray Transients (FXTs) are X-ray flares with durations ranging from a few hundred seconds to a few hours. Possible origins include the tidal disruption of...

    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...
