The HST/ACS GGC Survey provides reliable photometry from 6 magnitudes below the main sequence turn-off to the level of the horizontal branch ( 3.5 magnitudes...

Using data collected as part of the Hubble Space Telescope Advanced Camera for Surveys (ACS) study of Galactic gobular clusters, we present photometry and...

The HST/ACS Survey of Galactic globular clusters is a Treasury project designed to obtain photometry with S/N ≥10 for main sequence stars with masses ≥ 0.2M&sun...

Based on our large and homogeneous photometric database of globular cluster observations taken with the Advanced Camera for Surveys aboard the Hubble Space...

As part of The HST/ACS Survey of Galactic Globular Cluster, we have imaged the globular clusters that are canonical members of the Sagittarius dSph galaxy (Sgr)...

We have built a hybrid turbulence profiler measuring simultaneously the atmospheric turbulence structure with a Shack- Hartmann wave front sensor and a G-SCIDAR...

Trojans are a significant portion of the small bodies population located within two clouds in the L4 and L5 Lagrangian points of Jupiter's orbit. The study of...

We use the catalogue of HII regions obtained from a high quality continuum-subtracted H_α image of the grand-design spiral galaxy NGC 7479, to construct the...
