Long suspected on theoretical grounds and supported by tantalising observational evidence, the connection between supernovae and gamma-ray bursts was definitely...

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...

The sunspot record since 1610 shows cycles of magnetic activity with an irregular distri- bution of amplitudes and with a period around 11 years; they are...

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...

We will provide an update on the participation of the IAC in the Sloan Digital Sky Survey. The survey is currently in the SDSS-IV phase (2014-2020), running...

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...

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...
