The most powerful cosmic engines in our universe are fueled by compact objects such as black holes and neutron stars. These cosmic engines accrete large amounts of material and eject matter in the form of jets traveling at near the speed of light. Recent groundbreaking discoveries of gravitational waves from systems harbouring compact objects and the direct imaging of the black hole shadows...
A black hole X-ray binary produces hard X-ray radiation from its corona and disk when the accreting matter heats up. During an outburst, the disk and corona co-evolve with each other. MAXI J1820 + 070 (ASASSN-18ey) is a low-mass BH X-ray binary, discovered in X-rays with MAXI on 11 March 2018. During the 2018 outburst, this source underwent the rising hard state, the soft state, and then the...
