India, Jan. 29 -- The Government of India has issued a release:
Astronomers have unravelled the mystery behind an intriguing flicker that they noticed in black hole systems, using advanced computer simulations.
Black holes, the most compact objects in the Universe with strong gravitation are studied indirectly by observing the electromagnetic radiation emitted by matter surrounding them. Matter falling toward a black hole due to the strong gravitation, first collects in a temporary structure called an accretion disc.
The behavior of this disc controls how energy and radiation are produced. When the motion of matter in the disc is mainly rotational, the inward flow slows down and the radiation generated are emitted as thermal radiation. H...
