Magnetized disc-outflow symbiotic model around black holes
Abstract
Theoretical and observational inferences reveal that accretion and outflows/jets are strongly correlated through fundamental conservation laws. All well-known jetted sources with accreting black hole systems indicate a signature of hot advective accretion flow and a dynamically important magnetic fields at the jet footprint. We inter-connect here the disc and outflow/jet for magnetized, viscous, optically thin, geometrically thick, 2.5-dimensional hot advective flows around black holes. The magnetic fields are captured from the environment, say interstellar medium or companion star, and dragged inward with continuous accretion process. This disc becomes magnetically dominated in vicinity of a black hole due to flux freezing. The accretion geometry as well as energetics of the accretion induced outflows/jets strongly depend on the mass and spin of the black hole, accretion rate, and magnetic field strength. We suggest, this magnetically dominated accretion powered system can easily explain the energetics of the ultraluminous X-ray sources in their hard power-law dominated states.
