Scientists use AI to reconstruct energetic flare blasted from Milky Way's supermassive black hole

The Milky Way's central supermassive black hole Sagittarius A* screeshots from a 3D simulation of flares around Sgr A*Scientists have used artificial intelligence to construct a three-dimensional model of an energetic outburst, or flare, that occurred around the Milky Way's central black hole, Sagittarius A* .

The key result of this work, he added, is the recovery of what the 3D structure of radio brightness around Sgr A* might look like directly after a flare detection.galaxy, making it the nearest supermassive black hole and a prime candidate to study such flares," Levis said."To do that effectively, you still need an element of luck when ALMA observations coincide with a flare."

The supermassive black hole at the heart of the Milky Way Sgr A* seen in polarized light for the first time., then applied those concepts around supermassive black holes to a neural network. This network was then used create the Sgr A* model. The team found that this delivered conclusions about the environment around Sgr A* that are indeed predicted by theory, showing brightness is concentrated at several small regions within the accretion disk. Still, aspects of this work were surprising to Levis and the rest of the team.

Levis added that the fact ALMA measures not just the intensity of light but also its polarization gave the team a highly informative signal with clues about the 3D structure of flares around Sgr A*Going forward, Levis said he and the team intend to run the simulation while changing the parameters of the physics used to constrain the AI.
