Scientists detect a potential Intermediate-mass black hole in the Milky Way

487 black hole 1

By carefully analysing the gas densities present in the cloud they concluded that it harboured a very large "compact object" that had to be a black hole.

The huge black hole has recently been discovered by the astronomers, which is said to be in the center of Milky Way and hidden by the massive molecular gas's cloud. If the discovery is confirmed, it could indicate that our galaxy has grown by cannibalizing its smaller neighbors.

Kevin Schawinski, an astronomer from Swiss Federal Institute of Technology in Zurich, stated that, "It's a very careful paper and they have gorgeous data". "This is the first detection of an intermediate-mass black hole candidate in the Milky Way galaxy", he said. The black hole appears to be mid-sized and not almost as big as the giant ones present at the centers of galaxies.

One theory is that smaller black holes steadily coalesce into larger ones and these come together to form supermassive black holes at the hearts of galaxies, but until now, no definitive evidence for intermediate mass black holes has been found. Then they added Monday's find to the list of about 60 other known black hole "candidates".

Also, Tomoharu Oka form the Keio University in Japan, leads a team of scientists, which says that it has some solid evidences of the existing mid-sized black hole which has been hanging out in our galaxy since long. For example, black holes which consume gas are spotted as the gas shine brightly while approaching the hole. The Atacama Large Millimeter/submillimeter Array provided high-quality images of the cloud.

Using numerical simulations of the hidden object, they interpret it as being an IMBH that is not now accreting matter-the accumulation of particles by gravitationally attracting more matter.

Moreover, they found a source of radio waves next to the gas clump.

"Astrophysicists have been collecting observational evidence for both stellar mass black holes and supermassive black holes for decades, but even though we think the largest ones grow from the smallest ones, we've never really had clear evidence for a black hole with a mass in between those extremes".

But how did it form and how did it get there?

Oka and Keio believe this IMBH formed through the first option. Instead, the scientists suggest it is the former core of a dwarf galaxy that has been subsumed into the Milky Way, stripped of its stars, and is destined to one day fall into Sgr A*.

The molecular cloud named as the CO-0.40-0.22 was detected by the Nobeyama radio telescope, a 45-meter telescope in Japan's National Astronomical Observatory. They say the gravitational force is likely caused by a black hole measuring about 1.4 trillion kilometers across.

It's hard to find black holes because they're completely Black.
