In the center of this image is the quasar H1821+643, a rapidly growing supermassive black hole that astronomers have found is underachieving, despite producing intense radiation and a jet of particles seen in radio data from the Very Large Array, in red. Located in the middle of a cluster of galaxies, H1821+643 is surrounded by huge quantities of hot gas detected in X-rays by Chandra, in blue.
“The giant black hole is generating a lot less heat than most of the others in the centers of galaxy clusters,” said co-author Lucy Clews of the Open University in the U.K. “This allows the hot gas to rapidly cool down and form new stars, and also act as a fuel source for the black hole.”
