Scientists Discovered Black Hole: 100000 Times More Massive Than the Sun
Sep 07 2017
The spectrum of the source seemed to be very similar to Sagittarius A* (Sgr A*), and they estimated the radio source was apparently the supermassive black hole at the center of our Milky Way, but around 500 times less luminous. Using the deepest X-ray image ever taken, astronomers found the first direct evidence that massive black holes were common in the early universe. The gases in the cloud move at unusual speeds, and the scientists believed they were being pulled 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 smallest black holes, stellar black holes, form when certain types of stars explode at the end of their life cycles, but scientists are unsure how supermassive black holes form. Since astronomers have a collection of the evidences for detection of the star-sized, small black holes, which are said to be upto 10 times of the solar mass. That's a little like a city that's home to only children and the elderly, with no one in between. A enormous black hole has been discovered stowing away in a harmful gas cloud drifting around close to the core of the Milky Way. One hypothesis is that smaller black holes blend into bigger ones and these meet up to frame supermassive black holes at the hearts of universes, however up to this point, no complete proof of the dark hole has been found.
"That growth should happen in part by mergers with other black holes and in part by accretion of material from the part of the galaxy that surrounds the black hole".
The researchers are also reportedly working on identifying more black hole candidates. But if this is the case, where are all the black holes halfway between pint-size and leviathan? They propose that a dwarf galaxy was once subsumed by the Milky Way, and its core became this black hole. Eventually, Oka explained to The Guardian, the object will sink toward Sagittarius A*, closer and closer, until it's swallowed up, increasing the mass of Sagittarius A* as it joins it at the heart of our galaxy.
Researches have predicted that about 100 million holes should exist in the Milky way Galaxy out of which only 60 has been identified till now.
'Based on the careful analysis of gas kinematics we concluded a compact object with a mass of about 100,000 solar masses is lurking in this cloud'.
Astronomers in Japan collected data supporting the black hole's existence while exploring a cloud of molecular gas located near the center of the Milky Way, in which the gas moved at vastly different speeds. They say the gravitational force is likely caused by a black hole measuring about 1.4 trillion kilometers across.
CO-0.40-0.22 had a very large broadening, indicating its contents were moving rapidly.
At the center of the Milky Way Galaxy resides the Supermassive Black Hole (SMBH) known as Sagittarius A*. 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.
