    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 1: A Very Faint Globular Cluster Disrupting in the Outer Reaches of the LMC?
    We present the discovery of a very faint stellar system, SMASH 1, that is potentially a satellite of the Large Magellanic Cloud. Found within the Survey of the...

    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 I: survey introduction and first results for the Sagittarius dwarf irregular galaxy
    We introduce the Solitary Local dwarfs survey (Solo), a wide-field photometric study targeting every isolated dwarf galaxy within 3 Mpc of the Milky Way. Solo...

    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...

    Spectroscopic Analyses of Massive Blue Stars (Galactic or Extragalactic)
    We review recent advances in our understanding of massive stars through the analysis of their spectra. Improvements in model atmospheres and analysis methods...
