European Space Agency (ESA) researchers using the XMM-Newton space telescope have discovered the unusual behavior of a supermassive black hole in the Markarian 817 (Mrk 817) galaxy, located 430 million years from Earth in the constellation Draco. The activity of the gravitational funnel cuts off the main system’s supply of gas needed to create new stars. The study was published in the scientific journal magazine Astrophysical Journal (TAPJ).
Supermassive black holes are found at the center of any galaxy. In some cases, they are surrounded by gas and dust disks (accumulation disks) that feed the structures. The immense gravity of black holes superheats matter, causing it to glow and eject some of the matter at close to the speed of light. Such objects are called active galactic nuclei.
According to scientists, Mrk 817 exhibits much rarer and chaotic behavior; It creates ultrafast black hole winds by uncontrollably spewing gas from the accretion disk in all directions. Such “hysteria” leads to the fact that the hole deprives itself of power and displaces gas from the host galaxy, stopping the birth of new stars over a wide area.
Astronomers stated that the Mrk 817 black hole is the only one of its kind; Space researchers have never observed black holes this intense before. Experts hope that studying the object will provide a better understanding of its nature and how the hole manages to sustain a powerful cosmic storm for long periods of time.
