There are two other types of black holes, supermassive black holes that can be millions or billions times the size of the sun as well as stellar-mass black holes that are about a few dozen times the size of the sun. "Thus we are increasing the number of them by the new technique".
It's believed they could be the seeds of their more massive counterparts - merging together to form a big one. intermediate black holes might simply turn out to be their progenitors.
Black holes are hard to find because they do not emit any light.
Recent research has shown supermassive black holes are essential to the creation of galaxies, stars - and even life itself. While scientists have data supporting the existence of supermassive and small black holes, Science reports they lacked evidence of the mid-sized variety.
Professor Oka believes the newly found black hole may have managed to stay undetected because it is not bright, having insufficient mass accretion.
The discovery was made after they found a "peculiar" molecular cloud located near the center of the Milky Way, which according to the scientists displayed some highly unusual properties not seen in similar cosmic structures.
Astronomers detect the presence of a potential #black hole in our Galaxy.
Instead, researchers look to possible influences on nearby objects or disruptions in gravitation to detect these occurrences and, based upon observations of the cloud of molecular gas, scientists believe the most likely cause of these particular gravitational disruptions could be the existence of a black hole. But if there's big black holes and small black holes, there's got to be something in between, right? "It's the most promising evidence so far" for an intermediate mass black hole, says astronomer Kevin Schawinski of the Swiss Federal Institute of Technology in Zurich, who was not involved in the study. 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 leading theory is that they develop when IMBHs - which are created when multiple stars in young clusters collide - merge with others to form supermassive variants.
The existence of a new Milky Way black hole was first hinted at previous year by the researchers in a separate study. While it is just been hypothesized and not officially declared as identified. While the existence of such a black hole in our galaxy has nearly been settled, not the same can be said for other types of black holes.
The finding can possibly lead to proof for generational relativity, a step that scientists claim would "make a considerable contribution to the progress of modern physics".
