Theories of how galaxies, the fundamental constituents of large-scale structure, form and
evolve have undergone a dramatic paradigm shift in the last few decades. Earlier views …

The WFPC2 of the HST has been used to obtain high-resolution images of NGC 4038/4039
that go roughly 3 magnitudes deeper in V than previous observations made during Cycle 2 …

We analyze optical spectra of a sample of 502 galaxies in close pairs and N-tuples,
separated by≤ 50 h-1 kpc. We extracted the sample objectively from the CfA2 redshift …

We determine the mass function of young star clusters in the merging galaxies known as
the" Antennae"(NGC 4038/9) from deep images taken with the Wide Field Planetary Camera …

We analyse the properties of substructures within dark matter haloes (subhaloes) using a set
of high-resolution numerical simulations of the formation of structure in a ΛCDM universe …

We present an analysis of the globular cluster systems of 28 elliptical galaxies using archival
WFPC2 images in the V and I bands. The VI color distributions of at least 50% of the …

We further the recent discussion on the relation between the star formation rate (SFR) of a
galaxy and the luminosity of its brightest star cluster (SFR versus M brightest V). We first …

We have assembled a catalogue of relative ages, metallicities and abundance ratios for
about 150 local galaxies in field, group and cluster environments. The galaxies span …

We have compiled data for the globular cluster systems of 50 galaxies from the Hubble
Space Telescope Wide Field Planetary Camera 2 archive, of which 43 are type S0 or earlier …

We present images of the recent galaxy merger NGC 3256 obtained with the Wide Field
Planetary Camera 2 of the Hubble Space Telescope in B and I filters. We show that there is …
