The measurement of distances to individual stars with Gaia is enabling the construction of deep colour-magnitude diagrams (CMD) for large volumes within our...

We derive the bar fraction in three different environments ranging from the field to Virgo and Coma clusters, covering an unprecedentedly large range of galaxy...

Early-type (E/SO) galaxies follow tight relations such as the Fundamental Plane, the Color-Magnitude Relation or the Mg2-σ relation (Bender et al. 1992)...

In this paper we discuss the reason for the widely found discrepancy between Sérsic brightness law fitted along major and minor axes of elliptical galaxies. We...

We present the values of CN and Mg overabundances with respect to Fe, for early-type galaxies in 8 clusters over a range of richness and morphology. Spectra...

Using archival HST/WFPC2 imaging of 7 LMC globular clusters, and following the methods outlined in our previous study, we have reached the tightest constrain so...

Far infrared and sub-millimeter observations of quasars and normal star forming galaxies at z>6 have revealed the presence of large amounts of dust. At such...

The Asteroid Impact and Deflection Assessment (AIDA) is a joint US-European mission concept designed to demonstrate the effectiveness of an kinetic impactor for...
