X-ray Dips in AGN and Microquasars -- Collapse Timescales of Inner Accretion Disc
Mayur B. Shende, Prashali Chauhan, Prasad Subramanian
The temporal behaviour of X-rays from some AGN and microquasars is thought to arise from the rapid collapse of the hot, inner parts of their accretion discs. The collapse can occur…
