Abstract: | The propagation of light highly relativistic jets carrying a toroidal magnetic field is studied numerically. The results show that jets with high Poynting flux develop the conspicuous nose cones discovered earlier in simulations of classical magnetized jets. The size of the nose cone is significantly reduced in kinetic energy-dominated jets, which develop extensive cocoons. The magnetic field nevertheless plays a significant role in the jet–cocoon dynamics by allowing self-confined flows. The results are explained in terms of the properties of perpendicular magnetohydrodynamic shocks. |
