Astronomers at the California Institute of Technology (Caltech) are performing "computed tomography" (CT) scans of black holes. Using neural networks and the three-dimensional (3D) equivalent of CT scanning, they have reconstructed, for the first time, a map of the high-energy outbursts in the vicinity of the supermassive black hole 

Sagittarius A* at the center of the Milky Way. The findings, published in the 22nd issue of Nature Astronomy, show more clearly how flares form around black holes.

Supercomputer simulations show that matter spinning around a black hole in an accretion disk structure periodically erupts in high-energy events known as flares. Such events can be observed in X-rays, infrared and radio waves. However, it has been very difficult to reconstruct the three-dimensional structure of these flares from observational data.

Sagittarius A*, an extremely bright and complex source of radio waves at the center of the Milky Way, is the closest supermassive black hole to Earth and is considered the best target for studying black hole physics.2022 "Breakthrough results" released by a multinational collaboration of researchers -First photographs of a black hole obtained by humans. -The first photograph of a black hole obtained by humans, taken in Sagittarius A*. In recent years, scientists have been tracking high-energy outbursts in Sagittarius A*.
