Satellite galaxies that are near to massive primary galaxies in close pairs can have stellar population ages that are more similar to their primaries than...

The small and elusive Carina dSph still presents many open questions concerning its stellar populations and dynamical evolution. It presents a unique star...

This paper is part of a series devoted to the study of the stellar populations in brightest cluster galaxies (BCGs), aimed at setting constraints on the...

We present preliminary results of a photometric investigation on IC10 using data collected with ACS@HSTS and WFPC2@HST. We estimate the distance using the Tip...

We present preliminary results of a photometric investigation on IC10 using F555W and F814W data collected with WFPC2@HST covering two different regions. We...

We report the detection of intermediate-age and old stars belonging to the SMC at 6.5 kpc from the SMC center in the southern direction. We show, from the...

Photometry and long-slit spectroscopy are presented for 14 S0 and spiral galaxies of the Fornax, Eridanus and Pegasus cluster, and NGC 7582 group. The...

The radial profiles of the Hβ, Mg, and Fe line-strength indices are presented for a sample of eight spiral galaxies with a low surface-brightness stellar disc...

We present extensive photometric and spectroscopic study to give a new insight in the bulge stellar population. Super-solar α/Fe and its constant value along...
