Coauthors
Abstract	An originally low angular angular momentum accretion flow desegregates into two components: the component with viscosity parameter higher than a critical value becomes a Keplerian disk and resides on the equatorial plane, while the component having sub-critical viscosity parameter forms an advective flow which may form a shock at a few tens of Schwarzschild radii. The post-shock region has multiple functions: (a) It forms the outflows/jets which is required to be collimated and accelerated soon after; (b) It and the base of the outflow behave like Compton cloud and form the power-law component of a black hole spectra; (c) Its oscillation in presence of cooling produces Quasi-Periodic Oscillations in X-rays, especially when the cooling time scale roughly agrees with the infall time scale. This is the only available all comprehensive theoretical solution that exists in the literature and is capable of explaining every observational aspects. Numerical simulation and Monte-Carlo simulation reproduce observations strikingly well. We discuss the predictive power of this solution and at the end talk about the role that magnetic fields might play in this problem.
