The disappearance of a black hole with a mass of 3 to 100 billion times the mass of the sun was confirmed in the galaxy Abell 2261, which is 2.7 billion light-years from Earth, under mysterious circumstances, it was assumed which was in the center of the galaxy.

The arxiv.org site indicates that scientists initially used the Chandra X-ray Space Observatory to search for hot materials that fell into the X-ray-emitting black hole, but found nothing.
In the new study, the researchers analyzed more data, taking into account the possibility of the black hole being ejected from the parent galaxy as a result of its merger with a second galaxy. It is assumed that a supermassive black hole will form as a result of the merging of two holes, creating a gravitational wave.
The researchers observed indirect signs of the merging of two super holes: First, the nucleus of the galaxy, Abell 2261, became larger than expected for a galaxy of this size. Second, the distance from the galactic center to the nearest dense star cluster is about two thousand light years. This is a great distance that occurs when two closely related black holes begin to repel nearby stars.
But the new data with the Shanda Observatory and observations with the Hubble Space Telescope did not reveal the existence of the black hole itself. This can be explained by the fact that the black hole slowly absorbs material, making it invisible to astronomers, or because it “escaped” far from the center of the galaxy.
