Scientific paper

Parameters expected to be reasonable for extragalactic radio sources are used to perform a series of fairly high resolution 2D hydrodynamical simulations of expanding asixymmetric jets. Most of the conclusions drawn from preliminary low-resolution runs, particularly the slowing down in relatively shallow power-law atmospheres and the transition from conical to quasi-cylindrical beams after crossing the interface, are confirmed. Good agreement with analytical estimates for conical jet propagation is also found. These simulations indicate that sufficiently slow jets are found to become unstable after passing the interface, which was not clear from earlier simulations. Beams whose inputs of mass and momentum are removed both before and after crossing the interface are also examined. The resulting rarefaction waves, smoothed internal pressures, and slowed forward velocities imply that minimal shock acceleration of synchrotron emitting electrons occur once a jet is no longer being fed.
