3-D GRMHD Simulations of Disk-Jet Coupling and Emission |
Abstract _ |
We have performed a fully 3-D GRMHD simulation of jet formation from a thin accretion disk around a Schwarzschild black hole with a free-falling corona. The simulation results show that a bipolar jet is initially created. At later times, the accretion disk becomes thick and the jet fades resulting in a wind that is ejected from the surface of the thickened (torus-like) disk. This evolution of disk-jet coupling suggests that the jet fades with a thickened accretion disk. Recently we have developed two new codes: 3-D GRMHD: RelAtivIStic magnetoHydrodynamical sImulatioN (RAISHIN) code constructed by modern high-resolution shock-capturing (HRSC)techniques and 3-D GRPIC code. We have calculated free-free and synchrotron emission from the disks and jet/outflows obtained from our GRMHD simulations using a fully covariant radiative transfer formulation. |
