Scientists Observe Rare Supermassive Black Hole 'Double Belch'

"Our galaxy's supermassive black hole is now napping after a big meal, just like J1354's black hole has in the past". The hole's gaping maw is sucking up massive amounts of material, burping some of it out in a huge shockwave-like event, and then resting for a brief period before resuming its feast.

Ms Comerford announced the discovery at the 231st American Astronomical Society meeting in Washington DC.

Scientists have combined images of the J1354 galaxy, which is located 800 million light-years away.

"There are a lot of examples of black holes with single burps emanating out, but we discovered a galaxy with a supermassive black hole that has not one but two burps".

Ms Comerford explained: "Theory predicted that black holes should flicker on and off very quickly and this galaxy's evidence of black holes does flicker on timescales of 100,000 years - which is long in human timescales, but in cosmological timescales is very fast".

The team of researchers, that published a journal entry on the results, declared they believe the black hole could have burped twice thanks to a collision between two galaxies. For comparison, one light-year is roughly six trillion miles.

Scientists using some of mankind's most powerful space observation tools - the Hubble and Chandra space telescopes - have observed the black hole at the center of a far-off galaxy spewing hot gas in two separate events. The Apache Point facility is owned by the Astrophysical Research Consortium, a group of 10 US research institutions that includes CU Boulder.

When things get pulled inside the event horizon of black holes, sometimes great quantities of energy are also released in the process. The answer lies in a companion galaxy that is linked to J1354 by streams of stars and gas, said Comerford.

'The two-course meal for the black hole comes from a companion galaxy that collided with J1354 in the past, ' Nasa said in a statement. They saw a loop of gas that indicated the more recent belch.

Well, nearly nothing. As it turns out, supermassive black holes aren't always thorough when gobbling up star systems and solar debris.

"This galaxy really caught us off guard", said CU Boulder doctoral student Rebecca Nevin, a study co-author who used data from Apache Point to look at the velocities and intensities of light from the gas and stars in J1354. Researchers said that they could see this object having meal, nap and belch and repeating these activities. This happens especially if the main feed of the black hole is gas.
