Mumbai-Born Astrophysicist Discovers Black Hole 142 Times Heavier Than Sun

Mumbai: Karan Jani, an Indian-origin astrophysicist one of the several researchers with the Nobel-winning LIGO (Laser Interferometer Gravitational-Wave Observatory) consortium  discovered the gargantuan black hole.  Researchers have discovered a black hole that’s not only the oldest but also doesn’t qualify to exist, as per current understanding of the black holes. The gargantuan black hole is 142 times the mass of our Sun.

The discovery was made on May 21 and was labelled GW190521. The researchers belonged to two consortiums —  The LIGO (Laser Interferometer Gravitational-Wave Observatory) consortium and Europe’s Virgo collaboration. 1,500 researchers  were part of this discovery. With the help of gravitational wave detectors they spotted the gravitational wave possessing eight times the energy of the Sun, coming from roughly 17 billion light-years away.

 

Researchers claim that GW190521 was generated by a source which would have existed when our universe was nearly half of the age it’s currently at.

According to researchers, ‘this black hole is formed after the fusion of a black hole with 66 times the size of the Sun with another black hole with 85 percent the mass of the Sun. They claim that when these massive black holes fused together, they released energy worth eight solar masses that created the most powerful events in the universe since the Big Bang.

 

Karan Jani, ‘This detection confirms that there is a vast universe that has remained invisible to us. We have very limited theoretical and observational understanding of this elusive class of intermediate black holes’.

 

He added, ‘Our ability to find a black hole a few hundred kilometres-wide from half-way across the Universe is one of the most striking realisations of this discovery’.
