An average-sized black hole

Post by brian livesey »

Black holes come in different sizes. Small and supermassive ones have been discovered, and now an "average" black hole has been found. This fills the gap between black holes that are weighing in at the equivalent of just a few suns, and black holes that are equivalent to millions of suns. Until now, average black holes have been missing.
The newly discovered black hole lies in the centre of the globular cluster 47 Tucanae. It's weight is equivalent to 2,200 suns. "We want to find intermediate black holes because they are the missing link between stellar-mass and supermassive black holes," said Bulent Kiziltan of the Harvard-Smithsonian Centre for Astrophysics, who is the lead author of research published in "Nature".
"They may be the primordial seeds that grew into the monsters we see in the centres of galaxies today," he said.
