NRAO erlebt die erste bekannte Verschmelzung dreier Galaxien, von denen jede ihr eigenes aktives Schwarzes Loch hat

„“Triple active galaxies like this are incredibly rare, and catching one in the middle of a merger gives us a front-row seat to how massive galaxies and their black holes grow together,” said Dr. Emma Schwartzman of the U.S. Naval Research Laboratory, lead of the study.

“By observing that all three black holes in this system are radio-bright and actively launching jets, we’ve moved triple radio AGN from theory into reality and opened a new window into the life cycle of supermassive black holes.”“
