Indian astronomers make breakthrough discovery about black hole using AstroSat
May 20, 2024A team of Indian astrophysicists has made a significant discovery shedding new light on the physics of gas accretion and relativistic jet formation around black holes. This discovery involves the observation of ‘aperiodic (irregular) modulation’ of high-energy X-ray photons emitted from a black hole binary system during an unusual outburst phase. This breakthrough was made possible by observations from India's first dedicated multi-wavelength space observatory, AstroSat.
