Astronomers have discovered a super-massive black hole that is “burping” out gases after ingesting nearby matter. They have added that this black hole’s behavior is similar to what occured in the early evolution of universe.
Using NASA’s Chandra X-ray Observatory, astronomers have discovered a black hole at the center of a neighboring galaxy that is ejecting violent, powerful blasts after consuming stars. The expanse of the hot gas, which is present in the black hole, is also pushing cooler hydrogen gas in front of them.
Eric Schlegel, professor at the University of Texas at San Antonio, TX, and the lead author of the study, said “Apparently, black holes can also burp after their meal.”
According to the astronomers, these cosmic belches show the outburst in the supermassive black hole centered in the small galaxy NGC 5195. They have added that this phenomenon is caused by gas funneling in toward the black hole, thus generating enough energy to produce these ejections.
The astronomers have also discovered two arcs of X-ray emissions near the center of NGC 5195. In NGC 5195, the qualities of the gas around the X-ray-glowing arcs show that the outer arc has plowed enough material to induce the development of new stars. The astronomers added that these arcs represent fossils from two enormous blasts when the black hole expelled material outward into the galaxy. They believe that this activity is likely to have had a big effect on the galactic landscape.
“For an analogy, astronomers often refer to black holes as ‘eating’ stars and gas. Apparently, black holes are also letting out gases, which can be seen as a burp. Our observation is important because this behavior would likely happen very often in the early universe, altering the evolution of galaxies. It is common for big black holes to expel gas outward, but rare to have such a close, resolved view of these events,” added Schlegel.
The findings were presented at the 227th meeting of the American Astronomical Society (AAS) in Florida.
