Numerical Simulations Reveal the Origin of QPOs in Black Hole Candidates
Sandip K. Chakrabarti
We present results of various types of numerical simulations of black hole accretion disks and find that those flows which are relatively non-dissipative and which contain accretio…

Class Transitions in Black Holes
Sandip K. Chakrabarti
A black hole spectrum is known to change from the hard state to the soft state when the energy spectral index () in, say, 2-20 keV range changes from $α\sim…
