Astronomers Discovered Giant Black Hole: Mass Equal To 40 Billion Suns

Only a few months back, Scientists of NASA had captured the image of a Giant Black Hole for the first time. In April 2019, NASA had released the image of the black hole which lies in the center of Galaxy M87. And once again astronomers surprised us with the discovery of black hole.

Astronomers have recently discovered a Giant Black Hole. But, the most noteworthy thing is, its mass is huge. The mass of the black hole equals the mass of 40 billion Suns. The black hole is named Holmberg 15A. It’s lying almost 700 million light-years away from earth. Furthermore, it belongs to the Abell 85 galaxy cluster and situated in the center of the cluster. Holmberg 15A is one of the biggest black holes ever spotted. “The brightest cluster galaxy of the cool-core cluster Abell 85, consists of an ultra-diffuse central region, which is 2 mags fainter than the faintest depleted core of any early-type galaxy dynamically modeled”, according to the researchers.

How did they discover it?

Researchers had collected some photometric data at the Wendelstein observatory of Germany. The observation results confirm the existence of unusual i.e.near-exponential light profile of the galaxy’s core. Furthermore, they used orbit-based, axisymmetric Schwarzschild models to analyze the stellar kinematics of Holm 15A. New high-resolution, wide-field spectral observations obtained with MUSE at the Very Large Telescope. They found a supermassive black hole i.e. SMBH with a mass of (4.0 +- 0.80) x 10^10 solar masses at the center of the giant black hole Holm 15A.

the black hole Holmberg 15A is also one of the biggest black holes comprising of a dynamical detection in the local universe. Researchers compared it with N-body simulations of mergers lying in between galaxies with black holes. They observed that the amount of tangential anisotropy, besides, the overall shape of the light profile are pretty consistent with a common formation scenario. Furthermore, they found out that the black hole masses in cored galaxies, including Holm 15A, have an inverse relation with the central stellar surface brightness as well as mass density.

Researchers also want to study further the giant black hole and conduct more sophisticated and detailed modeling around it. Consequently, they can figure out how exactly these black holes are formed and how many such giant black holes are there around the Universe.
