Astrologers have noticed a hidden black hole by its influence on the interstellar gas cloud. This dark hole of medium mass is considered one of the more than 100 million silent dark holes that are supposed to hide in the galaxy. These results provide a fresh way to search for other hidden dark holes and can help us understand the rise and evolution of dark holes.

Dark holes are objects with a similar strong gravity, in fact, that nothing, covering the light, has the ability to escape beyond the horizon of events. Because dark holes do not emit light, astrologers are obliged to make a conclusion about their existence from the impact of their gravity on other objects. The set of dark holes ranges from about 5 one more mass of the Sun to supermassive dark holes in millions one more mass of the Sun. Astrologers believe that actually small dark holes are connected and gradually grow into giant ones, but no one has ever found a black hole of the perineal mass weighing hundreds or thousands of one more than the mass of the Sun.

A research team led by Shunya Takekawa of the state astronomical Observatory of the Land of the rising sun discovered HCN-0.009-0.044, a gas cloud unusually moving close to the center of the galaxy at a distance of 25,000 light years from Earth in the Sagittarius galaxy. They used ALMA (Atacama Large Millimeter/submillimeter Array) to perform studies of clouds with the highest resolution and noticed that it revolves around a bulky invisible object.

Takekawa talks: "detailed kinematic test has proven, in fact that big a lot, 30 000 one superior to the mass of the Sun were concentrated in a region much least than our Solar system. This and the unavailability of some observed object in this tight space shows on the black hole mass to the crotch. By sorting out other abnormal clouds, we trust to reveal other quiet dark holes."

Tomoharu Oka, doctor of the Keio Institute and head of the group, adds: "it is noteworthy that this dark hole of the perineal mass was found only 20 light years from the supermassive dark hole in the center of the galaxy. In the future, it will fall into a supermassive black hole, similar to how gas is currently entering it. This supports a fusion model for lifting a dark hole."

These results were published in Takekawa et al. "The Directive of another perineal mass of a dark hole in the space center" in the year to January 20, 2019.
