    Satellite galaxies can carry on forming stars when they pass close to their parent galaxies
    Historically most scientists thought that once a satellite galaxy has passed close by its higher mass parent galaxy its star formation would stop because the...

    Seeking footprints of the primeval Universe in dwarf galaxies
    We present the star formation histories (SFHs) of four isolated dwarf galaxies, Cetus, Tucana, LGS-3, and Phoenix, as a function of galactocentric radius. Our...

    Shedding light on the darkest galaxies: the Local Group dwarfs
    Crucial issues in cosmology and astrophysics are to understand the process of galaxy formation and evolution and the nature of what appears to be the dominant...

    SMASH: Survey of the MAgellanic Stellar History
    The Large and Small Magellanic Clouds are unique local laboratories for studying the formation and evolution of small galaxies in exquisite detail. The Survey...

    Solo dwarfs - III. Exploring the orbital origins of isolated Local Group galaxies with Gaia Data Release 2
    We measure systemic proper motions for distant dwarf galaxies in the Local Group and investigate if these isolated galaxies have ever had an interaction with...

    Solo dwarfs II: the stellar structure of isolated Local Group dwarf galaxies
    The Solo (Solitary Local) Dwarf Galaxy survey is a volume-limited, wide-field g- and i-band survey of all known nearby (<3 Mpc) and isolated (>300 kpc from the...

    Spatial dependence of the star formation history in the central regions of the Fornax dwarf spheroidal galaxy
    We present the star formation history (SFH) and the age-metallicity relation (AMR) in three fields of the Fornax dwarf spheroidal galaxy. They sample a region...
