Jorhat scientist’s quantum leap on black holes.

Milky Way Galaxy

Guwahati/ 10th April’2017(Prag News Desk): The phenomenon of the super-massive black holes swallowed in the Milky Way galaxy happened six million years ago. And to probe into the manners of the galaxy and the black hole, a new research comes into being under a scientist from North East India.

Rongmon Bordoloi and his team from Massachusetts Institute of Technology in Cambridge have found out that several distant quasars can be seen through the northern half of the Fermi Bubbles, an outflow of gas expelled by the Milky Way galaxy’s hefty black hole.

“Six-nine million years might sound like a long time in human years. But in terms of cosmic timescale, it is like the blink of an eye. Just to give you the scale, the universe is approximately 13.7 billion years old, and the dinosaurs became extinct around 66 million years ago. So the last meal that the supermassive black hole of the Milky Way had was after the dinosaurs became extinct, for the first time, we have traced the motion of cool gas throughout one of the bubbles, which allowed us to map the velocity of the gas and calculate when the bubbles formed,” Bordoloi said.

A black hole is a dense, compact region of space with a gravitational field so intense that neither matter nor light can escape. The supermassive black hole at the centre of our galaxy has compressed the mass of 4.5 million Sun-like stars into a very small region of space.

Asked when the next aline phenomenon,  Bordoloi hinted that , “Recently a binary star called G2 (with a mass of several earth masses) came very close to falling into the supermassive black hole at the centre of the Milky Way. Somehow it didn’t fall through and survived.There was some increased activity in terms of X-ray flares which could be due to a change in the strength of winds from nearby massive stars that are feeding material to the black hole. But in short, we don’t know when the next big meal would be. There are stars orbiting the galactic centre, and if they fall into the black hole at some point, we might see a good light show.”
