In this article we present the survey STREGA, that has been proposed as part of the VST GTO (VLT Survey Telescope Guarantee Time of Observation) that will be given to the INAF-OAC in exchange for the construction of the telescope (see Alcalàet al., this volume). This survey will cover an area of about 150 sq. deg., searching for the southern

The small and elusive Carina dSph still presents many open questions concerning its stellar populations and dynamical evolution. It presents a unique star formation history, with well separated episodes over a time of ˜10 Gyr. However, the complex star formation history does not seem to have caused a strong chemical evolution of its stellar content

We present Spitzer/IRS spectra of a small sample of galactic OHPNe. This is a rare class of transition sources displaying both radio continuum and OH maser emission at 1612 MHz. Our observations show that they are heavily obscured O-rich stars whose mid-infrared spectra are dominated by the simultaneous presence of strong and broad amorphous

We present results of the X-ray spectral analysis of the ˜370 ksec deep survey obtained with XMM-Newton on the Chandra Deep Field South (CDFS). Using sample of 127 sources with redshift identifications and with a raw count limit of 100 (pn detector) we explored both the physical properties of individual sources, and the general properties of two
