A long time ago in a quasar far, far away…
The most distant quasar yet discovered illuminates the early universe…
It’s Complicated: Three-Body Interactions Can Affect LIGO’s Binary Black Hole Mergers
Though black holes may start as strangers, interactions between several of them — not just the two component masses — can lead to LIGO-esque mergers.
Extinction events from giant space explosions: a cosmological perspective
Supernovae and Gamma Ray Bursts are expected to wipe out any complex life in the neighborhood. Today’s paper looks at how common these events are in different galaxies over time.
Feeding black holes through galactic bars
Galactic bars channel gas into the central regions of spiral galaxies to birth new stars. Are they also responsible for lighting up the black holes?

Astrophysical Classics: The Lost Art of Fishing in a Black Hole
In a strange, half-lost, piece of work Roger Penrose draws four figures dropping their lines into the depths of a black hole, and in doing so finds a new and hugely influential way to steal energy away from the heart of a spinning singularity.
Predicting a 21cm AGN reionization signal
Can we detect the signature of an AGN reionization?
