New black hole map depicts “largest-ever volume of universe”
New Delhi, Mar 19 (PTI) Scientists have mapped about 1.3 million of active supermassive black holes in three dimensions, depicting the “largest-ever volume of the universe”.
As the gravitational pull of these black holes living at the centres of galaxies “gobbles up” nearby gas, the process generates extremely bright disks – called quasars – and sometimes jets of light that telescopes can observe.
The team of scientists, led by New York University in the US, said that the map could help understand dark matter better, as the galaxies hosting these quasars are surrounded by “massive halos” of the invisible matter exerting gravity, but not colliding with particles.
