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...

This talk is divided into two related parts. First, we will call your attention to a basic, but often overlooked worrying fact, and presents ways of dealing...

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...

In recent years it has become clear that stars can migrate across large regions of the disk without increasing substantially the velocity dispersion. I review...

Although there is increasing speculation that the evolution of galaxy bulges may be regulated by AGN-induced outflows associated with the growth of the central...

In this talk, I will review the recently discovered infinite-dimensional symmetries that emerge in the near horizon region of black hole horizons. I will...

We used the GMOS integral field unit on the Gemini South telescope to investigate the kinematics of the circum-nuclear ionized gas in two active galaxies: NGC...

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...
