According to the study authors, one of the two black holes falls into the forbidden category known as the upper black hole mass gap and should be ‘impossible’.
Scientists at the Center for Gravitational Astrophysics at the Australian National University (ANU), which is part of the LIGO and VIRGO scientific collaborations, have detected the largest black hole collision ever.
According to an ANU statement, the miniature gravitational-wave signal captured by LIGO and VIRGO gravitational-wave observatories in the US and Europe last year, GW190521 came from two massive spinning, supermassive black holes weighing in at a massive 85. 66 times the mass and time of the Sun respectively.
However, according to the study authors, one of the two black holes falls into the forbidden category known as the upper black hole mass gap and should be ‘impossible’.
Talking about it, co-author of the publication from ANU, Professor Susan Scott said that it is believed that black holes are the vacuum cleaners of the universe, sucking everything in their paths.
She adds, “They also suck other black holes and it is possible to build larger and larger black holes from the collisions of black holes of earlier generations. Our known collision may contain massive ‘impossible’ black holes.” . Produced in this way. “
According to the study authors, both black holes merged when the universe was about half its present age. This made him an even larger black hole, 142 times the mass of sin, and the largest black hole ever seen through gravitational-wave observations.
Professor Scott said, “A collision black hole lies in the desert of a black hole between 100 and 1,000 times the mass of the Sun.”
They said that they are very excited to gain the first direct observation of an IMBH on this large scale.
“We also looked at how it was formed, confirming that IMBH could be produced through the merger of two small black holes,” Professor Scott said.
An ANU statement said another recent study by scientists using Caltech’s Zwiki Transient facility has seen light flashes along with the collision.
The study authors state that it is surprising as a black hole and their mergers are dark for telescopes. They think the newly formed black hole would have received a kick from the collision and shot in a new direction, which surges and lightes through a gas disc around the supermassive black hole.
