Ultramassive Black Holes Larger Than Mass Of The Sun
Ultramassive black holes may be more in the universe than previously thought, has a mass ranging from several million to several billion of the solar masses
Astronomers have long known about the largest class of black holes called supermassive black holes. Galaxies are believed to have a supermassive black holes at its center, the masses range from a few million to a few billion of the solar masses.
Ultramassive Black Holes
The research was conducted by a team of astronomers led by Dr.Julie Hlavacek-Larrondo of Stanford University, which was released on Wiley Onlinelibrary ‘Monthly Notices of the Royal Astronomical Society‘. Dr. Hlavacek-Larrondo said the results showed the possibility of many more ultramassive black holes in the universe than previously thought.
The results of the analysis of the brightest galaxies in the sample of 18 clusters of galaxies, suggesting that at least ten of the galaxies containing black holes in masses between 10 and 40 billion of the solar masses. About ten times larger than previously thought, astronomers call it an ultramassive black holes.
The research team estimated the mass of of black hole in the sample using an established relationship between the mass of the black hole, and the amount of radio waves X-rays are produced. This relationship is called the basal plane of black hole activity, according to data on the black hole masses ranging from 10 solar masses to a billion solar masses.
