Description
Different types of astrophysical black hole sources show variable accretion flows. They are found in gamma ray bursts, active galactic nuclei and radio loud objects such as blazars. These objects often have relativistic jets pointing at a small angle from our line of sight. Observational studies have found correlations between the minimum variability time-scale and Lorentz factor for these sources. The variability of the inflow can be transmitted to the outflow properties. Motivated by the observational properties of black hole sources, the accretion inflow and outflow properties are investigated by numerical GR MHD simulations.
