Supermassive black hole eats, burps and naps

Scientists catch supermassive black hole burping- twice

Great plumes of gas, matter and radiation can be ejected by black holes, and in fact, scientists theorized that these "burps" ought to come at pretty quick intervals if a black hole is well fed. "Fortunately, we happened to observe this galaxy in a moment where we could clearly see both events".

These supermassive black holes are million times heavier than the Sun and scientists consider that these holes are in the centre of every galaxy.

Our galaxy has a supermassive black hole at its centre as well, which has also ejected material at one time over the past few million years.

Comerford presented the team's findings in a January 11 press briefing at the 231st meeting of the American Astronomical Society held January 8-12 in Washington D.C. The Galaxy is known as J1354, which is around 900 million light years away from Earth.

While astronomers have predicted this type of event before, it has never been observed directly.

Julie Comerford, a scientist at the University of Colorado Boulder, stated that right now the supermassive black hole is in the sleep phase of the feats-burp-nap cycle and it's just waiting for its next meal. For comparison, one light-year is roughly six trillion miles.

Astronomers were studying SDSS J1354+132 (J1354 for short) when the Chandra observatory detected a "bright, point-like source of X-ray emissions" from its center, sure signs of a black hole. The Apache Point facility is owned by the Astrophysical Research Consortium, a group of 10 US research institutions that includes CU Boulder. To the north they saw a loop of gas that signaled the more recent burp.

The team said the cloud of ejected gas had already spread 30,000 light years from the black hole.

Astronomers have caught a massive black hole letting out a "double burp" after bingeing on hot gas.

The researchers think the black hole erupted twice because it consumed two separate meals.

"There's a stream of stars and gas connecting these two galaxies". The team concluded that material from the companion galaxy swirled into the center of J1354 and then was eaten by the supermassive black hole. It was spotted reflecting bright light because of the excessive gas it inhaled.

'This collision produced a stream of stars and gas that links J1354 and the other galaxy.

Even our Milky Way galaxy has had at least one burp, said Comerford. A 2010 study discovered gamma-ray "bubbles" that extend some 50,000 light-years end-to-end from the center of our galaxy.

Black holes follow a predictable cycle of feasting, burping and then napping. She added that if our solar system was close to the black hole than it would be hazardous for us.
