The supermassive Black Hole discovered by NASA’s Chandra X-ray Observatory burps following a massive meal of star and gas. This outburst has repercussions on the galactic environment. In other words, it affects how the space around the black hole is located. According to NASA, this supermassive black hole is quite near to the Earth – about 26 million light years away – which astronomically-speaking is just around the corner. This outburst or burp was discovered by scientists in the supermassive dark hole. It is located in NGC 5195., a small galaxy. This is the ‘companion galaxie’, which is merging into NGC 5194,, a larger spiral galaxy also called ‘The Whirlpool. The X-rays arcs identified by Schlegel’s group in the spiral galaxy NGC 5195.

The belching of black hole gas is a common occurrence in the early Universe. Dr. Eric M. Schlegel (Vaughan Family Professor at The University of Texas, San Antonio), said that “eating” stars and gases are often used to describe them as black holes. Black holes are also known to burp after eating. This observation is crucial because it would be very common in the early universe. It could alter the evolution of galaxies. The Astrophysical Journal also accepted their paper. Two arcs were detected by Dr. Schlegel, and Laura Vega (a graduate student at Fisk-Vanderbilt University’s physics program), in Chandra data. They are located near the centre of NGC 5195.. Professor Christine Jones (CfA), a Harvard-Smithsonian Center for Astrophysics lecturer, stated that the arcs could be outburst fossils. She is a co-author of the Chandra data. “We believe these arcs reflect fossils from two huge blasts when material was expelled outwardly into the galaxy. The activity was likely to have had an enormous effect on the galaxy’s landscape. An artist’s illustration showing the Chandra spacecraft while in orbit.

Just outside of the outer Xray arc, scientists found a narrow region of emission from comparatively cool hydrogen gas. This optical image was taken using the Kitt Peak National Observatory 9-meter telescope. It is located at 2 ,096m (6 ,880ft) Kitt Peak in Arizona-Sonoran Desert. The hotter, more X-ray emitting gases may have swept away the hydrogen gas at the center of the galaxy. Scientists believe this to be a case where a supermassive dark hole has impacted its host galaxy through a phenomenon called ‘feedback. The properties of NGC 5195,’s gas around the Xray-glowing arches suggest that enough material has been spewed by the outer arc to allow for the creation of new stars. Marie Machacek (astrophysicist at Smithsonian Astrophysical Observatory in the High Energy Astrophysics Division) said that black holes do more than destroy, they also create. “We believe feedback prevents galaxies becoming too big. It can also be responsible for the formation of some stars. It is clear that black holes are capable of creating, and not just destroying.” Professor Schlegel and his colleagues think the explosions from the supermassive dark hole at NGC 5195, may have resulted from the interaction between the smaller spiral galaxy and its bigger companion. This caused gas to flow in toward the black hole. Outbursts are the result of energy created when matter falls in. Scientists estimate it took between one and three million years for an inner arc’s current location to be reached, and three to six millions years to get to its present position for an outer arc. Because of their location in the galaxy, the arcs can also be significant. These arcs are not located in an area where outflow (rapid winds) can be detected from supermassive black hole activity elsewhere in galaxies. However, they do exist within larger cavities and filaments observed in hot gas surrounding several large galaxies. They could be a rare glimpse of an intermediate stage in the feedback process between interstellar and black holes. BBC Video: Meet the Supermassive Black Hole experts
