Detection
The black hole was detected in 2016 by AstroSat of ISRO
The Black hole was detected for the first time in 2016 by the first dedicated astronomy satellite of ISRO and India, AstroSat.
Located in the 4U 1630-47 binary star system, the black hole is revealed to give an unusual burst of X-rays.
NASA's Chandra X-ray observatory confirmed the findings of ISRO, and scientists from several institutions led by the Tata Institute of Basic Research (TIFR) discovered that the Black hole was unusual.
Local manufacturing instruments aboard the AstroSat spotted the black hole
The SXT-type instruments and the large-area X-ray proportional meter (LAXPC) built inside the ship were the first to observe the black hole and correctly interpret its unusual flakes. back in 2016.
Results
The black hole rotates at a speed close to the speed of light
The study revealed that unusual X-ray bursts were caused by the falling of the gas and dust in the black hole, about 10 times the mbad of the sun
In addition, scientists discovered that the black hole was spinning at an extremely fast speed – close to the speed of light.
Based on Einstein's theory of general relativity, black holes with such a high "rotational speed" are able to rotate the space around itself.
Signification
What is the significance of the finding?
The findings make this finding the fifth black hole observed as having such a high rotational speed.
Why is it important?
Well, if we badume that the conditions around the black holes are correct, black holes at high rotational speeds, badociated with gaseous materials that penetrate it, could be the key to understanding how galaxies are formed in the universe.
