Obscured active galactic nuclei
RC Hickox, DM Alexander - Annual Review of Astronomy and …, 2018 - annualreviews.org
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 …

Supermassive black holes at high redshift are expected to be obscured by their massive host galaxies' interstellar medium
We combine results from deep ALMA observations of massive (M*> 10 10 M⊙) galaxies at
different redshifts to show that the column density of their interstellar medium (ISM) rapidly …
