Cool outflows in galaxies and their implications
Neutral-atomic and molecular outflows are a common occurrence in galaxies, near and far.
They operate over the full extent of their galaxy hosts, from the innermost regions of galactic …

Active galactic nuclei flicker: an observational estimate of the duration of black hole growth phases of ∼105 yr
K Schawinski, M Koss, S Berney… - Monthly Notices of the …, 2015 - academic.oup.com
We present an observational constraint for the typical active galactic nucleus (AGN) phase

What drives the growth of black holes?
DM Alexander, RC Hickox - New Astronomy Reviews, 2012 - Elsevier
Massive black holes (BHs) are at once exotic and yet ubiquitous, residing at the centers of
massive galaxies in the local Universe. Recent years have seen remarkable advances in …
