New research based on simulations using the Blue Waters supercomputer at the National Center for Supercomputing Applications (NCSA) at the University of Illinois, reveals that when galaxies assemble extremely rapidly—and sometimes violently—that can lead to the formation of very massive black holes. In these rare galaxies, normal star formation is disrupted and black hole formation takes over.

“We on the Blue Waters Project are very excited about this accomplishment and very pleased that Blue Waters, with its unique capabilities once again enabled science that was not feasible on any other system,” said Bill Kramer, the Blue Waters Principal Investigator and Director. “We look forward to helping continue these great research efforts.”

This new study, published in Nature and supported by funding from the National Science Foundation, the European Union and NASA, is led by researchers from Georgia Institute of Technology, Dublin City University, Michigan State University, the University of California at San Diego, the San Diego Supercomputer Center and IBM. Their research finds that massive black holes form in dense starless regions that are growing rapidly, turning upside down the long-accepted belief that massive black hole formation was limited to regions bombarded by the powerful radiation of nearby galaxies. Conclusions of the study, also finds that massive black holes are much more common in the universe than previously thought.
