The central area of ​​the Milky Way with SgrA*

An article accepted for publication in the journal “Astronomy & Astrophysics” reports a study on Sagittarius A*, or SgrA*, the supermassive black hole at the center of the Milky Way, observed during a flare after it swallowed gas and dust in large quantities. A team of researchers used observations conducted simultaneously in 2019 with the GRAVITY instrument on ESO’s VLT interferometer and with the Spitzer, NuSTAR, and Chandra space telescopes to obtain infrared and X-ray data of the flare. This made it possible to create a detailed model of that type of flare.
