“In addition to stars, gas clouds can also be destroyed by small businesses and their binaries,” they said in the same paper. study. “The main difference is that unlike stars, which are always much smaller, clouds can be comparable to or even larger than binary separations.”
Looking at the results of previous research Numerical modeling studies of this type of situation also suggest the presence of gas clouds. Just like the hypothetical supermassive black hole binary in the model, AT 2021hdr is a system in which the black holes accumulate large amounts of material each time they orbit each other midway through each other’s orbits, forcing them to cross the cloud to complete their orbits. Must be. Its gravity pulls parts of the cloud apart. , each time it passes through the accretion disk, it will eventually reach the accretion disk. Currently, they are thought to ingest 3 to 30 percent of the cloud every few cycles. Very large clouds produce large amounts of gas.
AT 2021hdr’s supermassive black holes are predicted to collide with each other and merge in another 70,000 years. They are also part of another merger, in which the host galaxy is gradually merging with a nearby galaxy that was first discovered by the same team (this does not affect the disruption of BSMBH due to tidal gas clouds). ).
How AT 2021hdr’s behavior evolves could tell us more about its properties, supporting or disproving the idea that it’s consuming a gaseous cloud rather than a star or something else. There is a gender. So far, it appears that these black holes don’t just get gas from what they eat, they eat the gas itself.
