Magnetic Domination of Recollimation Boundary Layers in Relativistic Jets    [PDF]

Susanna Kohler, Mitchell C. Begelman

We study the collimation of relativistic magnetohydrodynamic jets by the pressure of an ambient medium, in the limit where the jet interior loses causal contact with its surroundings. This follows up a hydrodynamic study in a previous paper, adding the effects of a toroidal magnetic field threading the jet. As the ultrarelativistic jet encounters an ambient medium with a pressure profile with a radial scaling of p ~ r^-eta where 2View original: http://arxiv.org/abs/1208.1261
