Observations have shown that massive galaxies at high redshift have much smaller sizes than galaxies of similar mass today. The mean stellar density of such...

Understanding the connection between mass assembly and star-formation rate is a key question in galaxy formation. It is now well-established that a significant...

I will present new results regarding the first ~2 Gyrs of cosmic time using very wide-field Lyman-alpha (Lya) narrow-band surveys, including a large, matched...

Massive stars dominate the light output of entire galaxies, with luminosities in excess of 10 5 L⊙. This makes them powerful probes with which to study a range...

The extragalactic background light (EBL) is of fundamental importance both for understanding the entire process of galaxy evolution and for gamma-ray astronomy...

With the aim of detecting cosmological gas accretion onto galaxies of the local Universe, we examined the Ha emission in the halo of the 164 galaxies in the...

FeII comprises up to one third of the line emission in AGNs. For that reason it is an important coolant that needs to be taken into accountto fully understand...

In this talk I will present my view on what we know and what we don't know about the so-called secular evolution processes in galaxies. I will focus on the...

The general picture of galaxy formation and evolution includes bars as the main drivers of the internal secular processes affecting the lifetime of disc...
