Stability of Magnetized Spine-Sheath Relativistic Jets
A new general relativistic magnetohydrodynamics (GRMHD) code “RAISHIN” used to simulate jet generation by non-rotating and rotating black holes with a geometrically thin Keplerian disk finds that the jet forms a spine-sheath (two-component) structure in the rotating black hole case. Spine-Sheath structure and strong magnetic fields significantly modify the Kelvin-Helmholtz (KH) velocity shear d...
متن کامل3D Relativistic Magnetohydrodynamic Simulations of Magnetized Spine-Sheath Relativistic Jets
Numerical simulations of weakly magnetized and strongly magnetized relativistic jets embedded in a weakly magnetized and strongly magnetized stationary or weakly relativistic (v = c/2) sheath have been performed. A magnetic field parallel to the flow is used in these simulations performed by the new GRMHD numerical code RAISHIN used in its RMHD configuration. In the numerical simulations the Lo...
متن کاملRecollimation Shocks in Magnetized Relativistic Jets
We have performed two-dimensional special-relativistic magnetohydrodynamic simulations of nonequilibrium over-pressured relativistic jets in cylindrical geometry. Multiple stationary recollimation shock and rarefaction structures are produced along the jet by the nonlinear interaction of shocks and rarefaction waves excited at the interface between the jet and the surrounding ambient medium. Al...
متن کاملRMHD Simulations of Magnetized Spine-Sheath Relativistic Jets
We have performed numerical simulations of weakly and strongly magnetized relativistic jets embedded in a weakly and strongly magnetized stationary or mildly relativistic (0.5c) sheath using the RAISHIN code. In the numerical simulations a jet with Lorentz factor γ = 2.5 is precessed to break the initial equilibrium configuration. Results of the numerical simulations are compared to theoretical...
متن کاملStability Properties of Strongly Magnetized Spine Sheath Relativistic Jets
The linearized relativistic magnetohydrodynamic (RMHD) equations describing a uniform axially magnetized cylindrical relativistic jet spine embedded in a uniform axially magnetized relativistically moving sheath are derived. The displacement current is retained in the equations so that effects associated with Alfvén wave propagation near light speed can be studied. A dispersion relation for the...
