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, in contrast to Fig. 5, are generated without the use of a jet tracer and illustrate both the emission of the ambient medium and the hidden jet structure. 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.
