..., the final 142-solar-mass black hole produced by the GW190521 merger lies within an intermediate mass range between stellar-mass and supermassive black holes. Along with rapid gas accretion, intermediate-mass black holes have been linked to the...
...other that finally join together. Several of the black holes formed from these mergers exceed 100 times the mass of our Sun, and are classed as intermediate-mass black holes. This type of black hole has long been theorised by astrophysicists, but has...
... of matter. Another idea is that that they are formed from mergers of many intermediate mass black holes. Many candidates for intermediate black holes have been proposed on the basis of their ultraluminous nature and lowtemperature blackbody spectral...
..., the team state that the star in question, if it was a TDE, would have to be a white dwarf being shredded by an intermediate-mass black hole. Either way, say the team, none of these scenarios can completely explain all of the observed properties...
