Russian radioastron telescope found evidence for the existence of a galaxy with a pair of supermassive black holes

OJ287 is a lacertid, a powerful source of electromagnetic radiation located at the center of the same name

galaxies in the constellation Cancer. Previously, scientists have suggested that in the center of the galaxy there are not one, but two supermassive black holes with masses of 18 billion and 100 billion solar masses.

Such a conclusion astronomers have done because of the unusualbehavior of one of the black holes - from time to time it flared up sharply, and its brightness increased several times. It is assumed that once every 12 years two supermassive black holes approach each other.

By usingRadioAstron, which ceased operation in January 2019, researchers studied the central regions of OJ287 and obtained data on the interaction of black holes with the accretion disk.

On the one hand, one cannot say that the twistedThe outbursts and curved disk necessarily indicate the existence of a double black hole—they could have arisen in other ways. On the other hand, our observations are fully consistent with the predictions of the theory and can most easily be explained by the fact that there are two black holes at the center of the OJ287 galaxy.

Earlier it was reported that Russian scientists plan to send the largest virtual radio telescope "Millimetron" for the lunar orbit in 2025.
