Total intensity maps of our 3D RMHD jet simulations using different electron scaling relations and a purely toroidal magnetic field morphology. The images highlight similar epochs in the jet’s evolution during each 3D RMHD simulation at 86 GHz. The images are created with a jet tracer which excludes the obscuring ambient medium. The images are comparable to the lower panels of Fig. 5 in which, in contrast to computing γ_min from the ratio of pressure to density, it is fixed to 10. The jet is viewed at i = 45° and propagates from top to bottom in each frame. From left to right: proportionality of the NTEs to the fluid’s density, internal energy density, and magnetic energy density. The jet structure does not show considerable differences although the jet is most edge-brightened for the most right proportionality.
