"[But] the origins of such supermassive black holes remain unknown".
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. Immensely strong radio waves were detected at the center of the cloud, further supporting the hypothesis that it contains a black hole. For example, black holes which consume gas are spotted as the gas shine brightly while approaching the hole.
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.
They discovered that the movement of the gases, which include carbon monoxide and hydrogen cyanide, was caused by huge gravitational forces.
Computer models suggest that this is most likely caused by an invisible compact object: an inactive IMBH that does not now accrete matter. The black hole is supposed to have a mass of around 100,000 times more than the sun, making it a special kind of black hole that has never been officially identified.
If it is confirmed that the research has found what appears to be an IMBH, this means that a new research field will appear, a new field in which supermassive black holes can be studied and understood.

He founded TicTocStop , a charity dedicated to children with Tourette syndrome, which he was diagnosed with in his teens. You may have seen the name Craig Carton trending in a lot of places and wondered what's up with him.
If their discovery can be confirmed, it would be the first ever evidence of an IMBH, which have always been viewed as the "missing link" in the evolution of these massive objects. If confirmed, this discovery will constitute the second-largest black hole to be discovered within the Milky Way.
Oka has yet to say if that'll result in the destruction of the world as we know it and we'll be sucked up into and destroyed by a vortex of incredible nothingness.
Black holes are hard to find because they do not emit any light. But they can be detected by their influence on nearby objects, for example if the black hole is in a binary pair with a star, or if it is consuming gas which gets heated as it approaches and shines brightly. So, using computer-based simulations, they determined that the most likely cause would be a "gravitational kick" caused by an object similar to a black hole. "Based on the careful analysis of gas kinematics, we concluded that a compact object with a mass of about 10 [Solar Masses] is lurking in this cloud". The smallest black holes form when particular types of stars explode at the end of their lives. The similarities could indicate the existence of a mid-sized black hole, the researchers say. Studies that have sought to locate Intermediate Black Holes (IMBHs), on the other hand, have found very little evidence of them.
Supermassive black holes have masses ranging from millions to billions of solar masses.
But Oko and his team posit that CO-0.40-0.22 used to be the nucleus of a dwarf galaxy that was slowly drawn into the Milky Way.
"Further detection of such compact high-velocity features in various environments may increase the number of non-luminous black hole candidate and thereby increase targets to search for evidential proof of general relativity", Oka said.
