    Reading the Chemical Evolution of the Fornax dSph
    Dwarf spheroidal (dSph) galaxies are the smallest, closest and most abundant galaxies in the Universe and therefore excellent laboratories to study star...

    Relative ages of Galactic globular clusters. Clues to the Milky Way formation time scales
    Based on observations with the Advanced Camera for Surveys (ACS), I will present accurate relative ages for a sample of 64 Galactic globular clusters. This...

    Resolved stellar populations in dSphs. What can they tell us about galaxy evolution?
    We present a comprehensive photometric study of the Fornax and the Andromeda II dwarf spheroidal (dSph) galaxies. It is based on the up-to-date deepest...

    Rotating stellar populations in the Fornax dSph galaxy
    We present a novel analysis of the internal kinematics of the Fornax dwarf spheroidal galaxy. Our results are based on the largest sample of spectroscopic data...

    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...
