The most realistic simulation of a black hole

At the center of every galaxy is a supermassive black hole. Now the combined experience of three researchers working on different properties of black holes has generated the most accurate model of Sagittarius A, the monster that resides at the center of our own galaxy, the Milky Way.

Detailed simulation of the movement of the gas surrounding the object

as collected IFL Sciencethe finding has been published in The Astrophysical Journal Letterscombine the detailed simulation of gas movement that surrounds the object with the observations of the famous black hole, whose first direct image was published only a few months ago, blinking. The blinking indicates that this finite region of space, Sagittarius A, feeds lazily on the gas that is surrounding it, but an exact understanding of how or why it does so is lacking.

Union of works to obtain the most holistic image of the black hole

Lena Murchikova, Chris White and Sean Ressler joined their respective works to get a more holistic picture of the black hole, creating the first single model that shows how gas travels in the galactic center. They found that the most likely scenario for the feeding of Sagittarius A is that the gas that leaves the stars at long distances falls into this finite region of space instead of a slow deflection of orbiting material.

“The result turned out to be very interesting”Lena Murchikova of the Institute for Advanced Study said in a statement. “For a long time, we thought we could largely ignore where the gas around the black hole was coming from. Typical models imagine an artificial ring of gas, roughly doughnut-shaped, at a great distance from this finite region of space. We find that such models produce flashing patterns inconsistent with observationsMurchikova said.
