Caltech researchers build the first 3-D recreation of a flare surrounding the Milky Way's supermassive black hole, Sagittarius A*.
Katie Bouman, a computer scientist and member of The Event Horizon Telescope collaboration, gained global recognition for her contribution to the development of the algorithm that helped capture this image of the historic black hole situated in the faraway galaxy M87.Caltech researchers have built the first three-dimensional recreation of a flare surrounding the Milky Way’s supermassive black hole, Sagittarius A*.
Caltech researchers were able to put together the first three-dimensional video by collating telescope data with an artificial intelligence computer-vision simulation technique. The video demonstrates how flares would look around Sagittarius A*. “It is a reconstruction based on our models of black hole physics. There is still a lot of uncertainty associated with it because it relies on these models being accurate,” said Aviad Levis, a postdoctoral scholar in Bouman’s group and lead author of the new paper. The scientists used cutting-edge computational imaging methods to create a technique that includes light bending caused by the black hole’s tremendous gravity.
