We present new and accurate optical photometry of the Bulge globular cluster NGC6528. The images were collected with ACS at HST and together with WFC3 (UVIS, IR) allowed us to measure the proper motion to separate cluster and field stars. We adopted two empirical calibrators and we found that NGC6528 is coeval with and more metal-rich than 47 Tuc

We present the full Star Formation History as a function of radius of the Fornax dSph galaxy. We also present the preliminary results of the spatial distribution of the stellar populations. We found significant differences in the populations as a function of the galactocentric radius, which may be the result from interactions between Fornax and

Dwarf galaxies in the Local Group allow to study in great detail the physical mechanisms responsible for the formation and evolution of galaxies. In fact, their resolved stellar populations allow to unveil their star formation and chemical evolution histories back to the earliest epochs. In particular, they can be used to constrain the efficiency

We present the star formation histories (SFHs) as a function of galactocentric radius of four isolated dwarf galaxies, Cetus, Tucana, LGS-3, and Phoenix. Our results suggest that beyond some distance from the center, there are no significative differences in fundamental properties of these galaxies. In the innermost regions, dwarf galaxies appear

We report on our ongoing project "Statistical studies of HII regions in the nearby extragalaxies". In EWASS 2014 we presented the overview of our detailed study of warm dust in the nearby Galaxy NGC 4321 (M100), which included new relations between the Halpha luminosity and the near-IR luminosity and temperature of some 275 HII regions in M100. In

Several ambitious scientific projects are currently pushing the limits of astrophysical spectroscopy, in terms of wavelength accuracy and long-term stability. These objectives put strong constraints also on the treatment of observational data, requiring dedicated software to be developed as an integral part of the instrument. In this context, a key
