CharlaReading 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...

CharlaRelative 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...

PublicaciónResolved 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...

PublicaciónRotating 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...

PublicaciónSeeking 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...
