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?
A treasure hunt for the origins of very high energy gamma rays
Today’s authors aim to answer the question: Where are very high energy gamma rays coming from?
Do black holes hug each other in AGN disks?
Thanks to gravitational waves, we have detections of black holes mergers. Now imagine they are embedded in AGN disks, can you guess what’s going to happen to them? The authors of today’s paper can tell you if your guess was correct!
Active Galactic Nuclei have a history of causing trouble
Many astronomers believe that AGN activity is responsible for suppressing star formation. However, it appears that maybe the past behaviour of AGN is what’s really to blame.
How to jump start a supermassive black hole
Active Galactic Nuclei are some of the brightest objects in the Universe. But what is responsible for switching on these supermassive engines?
Did we just see two black holes merge?
Today’s paper describes how we may have seen light from two black holes colliding with each other.
