Filaments in the Firmament Fend Off Fiery Fury
In a galaxy cluster menaced by twin fire-breathing supermassive black holes, can some flimsy fibers blunt the carnage?

Today’s authors peer deep into a galaxy cluster to look for signs of a radio phoenix spreading its wings!
A group of galaxies — some rich in dark matter, and some lacking dark matter completely — could be explained by a violent, destructive event from their past.
The distribution of galaxies clusters (BAOs) are a beloved tool for cosmological analysis. But what about cosmic voids? Stare into the void, and you might just learn something new!
How have magnetic fields in galaxy clusters evolved throughout cosmic history, and what can these fields tell us about magnetism in the early Universe? Thanks to a few tricks from radio astronomy, today’s authors have some answers.
Galaxies in the middle of clusters are usually huge, elliptical galaxies. So what is this spiral-shaped imposter doing here?
