If supermassive black holes can grow from TDEs or other means faster than the Eddington limit, this could explain how supermassive black holes were able to reach masses about a billion times higher than the sun when the universe was only about a billion years old. "We want to find intermediate-mass black holes because they are the missing link between stellar-mass and supermassive black holes," said lead researcher Bulent Kiziltan from the Harvard-Smithsonian Centre for Astrophysics. Using computer models, they were able to calculate that the globular star cluster must contain an intermediate-mass black hole about

Combined, the evidence suggests the presence of an IMBH weighing about 2,200 solar masses - taking into account the margin of error, the upper range of their calculations suggest it could be up to 3,700 solar masses, and as low as 1,400 solar masses. It was the first step toward a paper published today in the journal Nature that provides the best evidence yet that a globular cluster might harbor an intermediate-mass black hole.
New strong evidence supporting the existence of an intermediate-mass black hole is announced.
