This talk will address the preferred mass and time for galaxy formation, in dark-matter haloes similar to that of the Milky way but when the Universe was a few...

In the study of galaxy evolution, we do not care about the physical parameters of any one galaxy: we care instead about the distribution of galaxies in physical...

The origin of galaxy morphology has to be seen in the context of the hierarchical build up of structure and baryons expected in a CDM Universe. Star formation...

As early as 10 Gyr ago, galaxies with more than 10^11 M* in stars already existed. While most of these massive galaxies must have subsequently transformed...

Two competing effects appear to govern galaxy multiplicity (pairs orgroups) at low masses: while associations of low-mass haloes are naturally expected in a...

Apart from unique characteristics of galaxies at birth, a lifetime of different environments ("isolation", group, cluster) can also shapetheir main features. In...

Over the past years observations of young and populous star clusters have shown that the stellar initial mass function (IMF) can be conveniently described by a...

The Sloan Digital Sky Survey is currently the largest spectroscopic survey of extragalactic objects and one of the most ambitious observational programs ever...

The life cycle of baryonic matter in a galaxy is driven by the exchange of material between the interstellar medium (ISM) and stars, which are the agents of...
