Missing black holes found
Missing black holes found
Quote:
European researchers have found 30 previously hidden supermassive black holes anchoring faraway galaxies, which suggests there at least twice as many of the colossal gravity wells as thought.
Supermassive black holes hold as much matter as millions or billions of suns. The newfound black holes were long sought but went unnoticed because they lurk behind veils of dust and are so faraway that even the galaxies they anchor are difficult to examine in any detail.
"This discovery means that surveys of powerful supermassive black holes have so far underestimated their numbers by at least a factor of two, and possibly by up to a factor of five," said study leader Paolo Padovani from Space Telescope-European Coordinating Facility and the European Southern Observatory in Munich, Germany.
