The black hole at the center of the Phoenix Cluster is known as Phoenix Cluster Central Galaxy (PCG). The Phoenix Cluster is a massive galaxy cluster located approximately 5.7 billion light-years away from Earth in the constellation Phoenix. The PCG is a supermassive black hole residing at the core of this cluster. It is one of the most powerful known active galactic nuclei (AGN) and has been studied extensively to understand the interplay between supermassive black holes and their surrounding environments.
