The researchers explained that the ultra-low frequency gravitational waves originated from a large number of dancing monster black hole pairs with masses that
The leading theory shared by the astronomers is that these gravitational waves are coming from pairs of supermassive black holes sitting at the centre of galaxies.
Operated by the National Centre for Radio Astrophysics (NCRA), India's Giant Metrewave Radio Telescope (GMRT) located in Pune was among the six of the world's largest radio telescopes that paved the way for this discovery of nano-hertz gravitational waves.
