But there’s one particular size of black hole that has been especially evasive, even though astronomers have theorized that they should be plentiful.While there is ample evidence for the extra-large, supermassive kind as well as the much smaller, stellar-mass black holes, the in-between size, or so-called "intermediate mass" black holes, have thus far eluded detection.Astronomers now think they have found one — a black hole 100,000 times more massive than the sun, lurking inside a gas cloud near the middle of the Milky Way. It's located not far from supermassive black hole called Sagittarius A* that lies at the dead center of our galaxy.Researchers think that intermediate-mass black holes (IMBH) could be a missing link that helps explain how supermassive black holes are formed.“The observations are rather compelling, and it's going to be exciting as astronomers follow up this source,” astronomer and black hole researcher Kevin Schawinski of the Swiss Federal Institute of Technology in Zurich, who was not involved in the current study, told Seeker.RELATED: The Mystery of How Black Holes Collide and Merge Is Beginning to UnravelLast year, a team of researchers led by Tomoharu Oka from Keio University in Japan discovered “a peculiar molecular cloud” named CO–0.40–0.22, which was located 200 light-years away from the Milky Way’s center. The cloud had what the team called “extremely broad velocity width,” meaning it was moving very fast with varying velocities they could not explain. The researchers suspected a massive object was hiding inside, providing the gravitational kick for the variable and speedy gas flows.Oka and his team followed up their observations using the Atacama Large Millimeter/submillimeter Array (ALMA) Observatory in Chile, and have now reported their findings in a paper published this week in the journal Nature Astronomy. 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.“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. They said numerical simulations suggest that CO–0.40–0.22 is one of the most promising candidates for an intermediate-mass black hole.“If confirmed by others, having such an intermediate mass black hole in our Milky Way is going to open up so many exciting possibilities,” Schawinski said via email. “If there's one, maybe there are others?”RELATED: Here's Why Finding ‘Missing Link’ Black Holes Is So HardWhile astronomers understand how stellar-mass black holes form, the origins of supermassive black holes remain unknown. A stellar-mass black hole forms when a massive star goes supernova. This explosion, which can outshine an entire galaxy of stars for a short period of time, leaves behind the small, heavy core of a star. If this core is massive enough, it will collapse on itself and form a black hole. A typical stellar-class of black hole can be between approximately three and 10 solar masses.
