Medium-sized black hole seen lurking in the Milky Way

News Week reports about how the potential black hole was marked.

That's even more the case now that a supermassive black hole has been discovered in our very own solar system.

Scientists have picked up signs that the black hole is one hundred thousand times larger than the sun, and pretty much on the galactic doorstep of the supermassive black hole - Sagittarius A* - which lies at the dead centre of our galaxy. One theory, The Guardian said, is that smaller black holes eventually merge together to form larger ones.

These findings offer strong evidence of a mid-sized black hole, though it is not clear how it might have come to that location.

That accolade is reserved for Sagittarius A, which is anchored at the very centre of the galaxy and has a mass of 400 million suns.

In the study published in the journal Nature Astronomy, Tomoharu Oka, from Keio University in Japan, and colleagues reported a new candidate for IMBH after using a powerful telescope in Chile's Atacama desert toward a gas cloud 200 light years away from the center of the Milky Way. The reason for this interest has to do with the fact that gases in this cloud - which include hydrogen cyanide and carbon monoxide - move at vastly different speeds, which is something unusual for a cloud of interstellar gases.

According to computer models, the most likely cause was a black hole, not more than 1.4 trillion kilometres across.

Intermediate mass black holes are considered to be the missing link with respect to the cosmic objects.

It's hard to find black holes - because they are completely black. Black holes, by absorbing other nearby stars and integrating them with other black holes, turn into supermassive black holes, which might range more than of millions of solar masses. This unusual movement perplexed the researchers, so they chose to point the powerful ALMA telescope in Chile's Atacam desert at the cloud.

Besides, the theoretical studies predict that there may be 100 million to a billion numbers of the black holes exist in the Milky Way, from which only around 60 black holes have been detected officially.

"Based on the careful analysis of gas kinematics, we concluded that a compact object with a mass of about [100,000] solar masses is lurking in this cloud", Oka and his team wrote. With ALMA's extremely high-precision data, the researchers were able to confirm the wide distribution of velocities inside the gas cloud, but they also found a telltale clue: a spectrum of radio waves very similar to what Sagittarius A* produces, but about 500 times fainter.

The concept of Black holes was firstly predicted by Albert Einstein. As a result, the IMBH could have formed outside the Milky Way and was then incorporated into our galaxy along with its parent dwarf galaxy.

It's believed they could be the seeds of their more massive counterparts - merging together to form a huge one. intermediate black holes might simply turn out to be their progenitors.

Oka says his team will continue to observe CO-0.40-0.22* at other wavelengths and keep an eye on it long-term to see whether it shows variations in brightness known as quasi-periodic oscillations, which are highly characteristic of accretion disks around black holes; that would give the scientists a better handle on the black hole's mass. "This would make a considerable contribution to the progress of modern physics".
