A 2-DIMENSIONAL SIMULATION OF A RELATIVISTIC JET BENT BY AN OBLIQUE MAGNETIC-FIELD

We have investigated a relativistic jet injected into an oblique magne tic held in a slab geometry using a newly developed relativistic magne tohydrodynamic simulation code. The simulation code employs a simplifi ed total variation diminishing method. We compare the nonrelativistic and relativistic jets to find the relativistic effects when the jet pr opagates across the oblique magnetic field. Numerical results show tha t both the nonrelativistic and relativistic jets are bent by the obliq ue magnetic held. However, the relativistic jet is weakly bent compare d to the nonrelativistic one. We try to express the bending scale dete cted in the simulation with a simple model and find good agreement bet ween them. We apply the results to the explanation of the bending of t he extragalactic jets.
