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?
Blown away by Black Holes: Losing Planetary Atmospheres to Quasar Radiation
When it comes to habitability for Earth-like life, we’ve got more than just liquid water to worry about. Today’s astrobite looks at how planets could lose portions of their atmospheres to quasar radiation.
Star Formation Acceleration
Today’s paper discusses a new way to measure physical properties of galaxies—including, for the first time, “star formation acceleration.”
Same ol’ same ol’? Galaxy Clusters across Cosmic Time
X-ray studies of galaxy clusters tell us how the extremely hot gas is distributed within these gigantic structures. Looking at these clusters across different redshifts, what does one find?
