Ray-traced images of our jet propagating from top to bottom in total intensity (left column), in linearly polarized intensity (middle column), and circular polarization (right column). The pictures illustrate similar epochs in the jet’s evolution during each 3D RMHD simulation at 86 GHz. The jet carries a purely poloidal magnetic field (top row), a helical magnetic field (middle row), and a purely toroidal magnetic field (bottom row). Integrated values of the fractional linear and circular polarization are listed to the lower right in the middle and right columns. The purely toroidal field jet appears edge-brightened in contrast to the poloidal jet which is brightest along the spine.
