Do We Have the Abell-ity to Find A Recoiling Black Hole in A2261-BCG?
What powers the core of the bright galaxy A2261-BCG? A massive black hole in the middle? A recoiling black hole? The authors of today’s paper use X-ray data to try to find out!
Running up that hill: are some galaxy clusters moving away faster than others?
We discuss a new way to test the cosmological principle using X-ray studies of galaxy clusters in this Astrobite.
