Caption: Figure 10.
Synchrotron emission at 1.5 GHz from one snapshot of the R8 Arm model. The white bars represent the magnetic field direction estimated from polarization measurements. This is given by Equation (6) rotated by 90°. The black arrows represent the mass-weighted average magnetic field direction projected into the x–y plane (Equation (38)).
