Disguised black hole found in the early universe hidden behind gas cloud



A camouflaged black hole, one of the rarest sightings of black holes was found behind a gas cloud and dates back to the early years of the universe.

A recent discovery With the Chandra X-ray Observatory, astronomers found the hitherto most hidden black hole. The object is only about 6% of the era of the universe according to a statement by NASA .

Before these monstrous cosmic beings transform into supermassive black holes, they feed on a disk of surrounding matter whose process creates an extremely bright, compact source of light known as Quasar . During the early growth phase of a black hole, a dense gas cloud blocks the light from the quasar until the black hole stops consuming the gas.

"It is extremely difficult to find quasars in this disguised phase because so much of their radiation is absorbed by and from current instruments can not be captured, "said Fabio Vito, astrophysicist at the Pontificia Universidad Católica de Chile in Santiago, Chile, and lead author of a study that describes the research, said in the statement .

The team of astronomers originally observed 1

0 quasars found in the early Universe when researchers discovered that one of them, PSO167-13, was heavily occluded by gas.

"This was a complete surprise," said Niel Brandt, physicist at Penn State University and co-author of the study, in the statement. "It was like waiting for a moth, but seeing a cocoon instead."

The Quasar arose 850 million years after the Big Bang astronomers estimated the distance from Earth. The previous record holder for the farthest discovered Quasar was born 1.3 billion years after the Big Bang.

This discovery could help scientists better understand the growth phase of supermassive black holes and how they grow to billions of times the solar mass in a short space of time.

The study was published on June 20 on the preprint server arXiv.org and accepted for publication in the journal Astronomy and Astrophysics.
