Black hole accretion, jet formation, and wind

Black hole accretion is a fundamental physical process in the universe and is the primary power source behind active galactic nuclei (AGNs), black hole binaries (BHBs), and, possibly, gammaray bursts.Black hole accretion flows can be divided into two broad classes: cold and hot.Observations show that hot accretion flows are associated with jets. In addition, theoretical arguments suggest that hot flows should produce strong winds.
