Black Holes Exhale Enormous Gas Cloud
A giant cloud of superheated gas 6 million light years wide might be formed by the collective sigh of several supermassive black holes, scientists say.
The plasma cloud, detailed in April 10 issue of Astrophysical Journal, might be the source of mysterious cosmic rays that permeate our universe.
“One of the most exciting aspects of the discovery is the new questions it poses,” said study leader Philipp Kronberg of Los Alamos National Laboratories in New Mexico. “For example, what kind of mechanism could create a cloud of such enormous dimensions that does not coincide with any single galaxy or galaxy cluster? Is that same mechanism connected to the mysterious source of ultra high energy cosmic rays that come from beyond our galaxy?”
