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...

Series: XXVIII Canary Islands Winter School of Astrophysics: Solar System Exploration Topic: Exploring the Outer Solar System Lecture 1: TNOs: a brief history...

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

As of today, we know now more than 3000 planets orbiting other stars. The detection of planets through radial velocity gathers special attention in the world of...

The spectral analysis of HII regions allows one to determine the chemical composition of the ionized gas phase of the interstellar medium (ISM) from the solar...

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 RV method is responsible for discovering the majority of planets that orbit stars other than our Sun. However, one problem with this technique is that...
