Active galactic nuclei: what's in a name?
Active galactic nuclei (AGN) are energetic astrophysical sources powered by accretion onto
supermassive black holes in galaxies, and present unique observational signatures that …

Obscured active galactic nuclei
Active galactic nuclei (AGN) are powered by the accretion of material onto a supermassive
black hole (SMBH) and are among the most luminous objects in the Universe. However, the …

The bolometric quasar luminosity function at z = 0–7
In this paper, we provide updated constraints on the bolometric quasar luminosity function
(QLF) from z= 0 to z= 7. The constraints are based on an observational compilation that …
