    The Extensive Age Gradient of the Carina Dwarf Galaxy
    The evolution of small systems such as dwarf spheroidal galaxies (dSphs) is likely to have been a balance between external environmental effects and internal...

    The extremely low-metallicity tail of the Sculptor dwarf spheroidal galaxy
    We present abundances for seven stars in the (extremely) low-metallicity tail of the Sculptor dwarf spheroidal galaxy, from spectra taken with X-shooter on the...

    The Lazy Giants: APOGEE Abundances Reveal Low Star Formation Efficiencies in the Magellanic Clouds
    We report the first APOGEE metallicities and α-element abundances measured for 3600 red giant stars spanning a large radial range of both the Large (LMC) and...

    The MAGellanic Inter-Cloud (MAGIC) project - II. Slicing up the Bridge
    The origin of the gas in between the Magellanic Clouds (MCs), known as the Magellanic Bridge, has always been the subject of controversy. To shed light into...
