Projections with a depth of 300 kpc through our fiducial Mach 3 simulation at t = 180 Myr. These show: i) volume-weighted time since injection, ii) synchrotron-weighted time since injection, iii) volume-weighted magnetic field strength, and iv) synchrotron-weighted magnetic field strength. Regions with no injected tracers have been masked (see text for further details). Synchrotron emission is calculated at ν = 150 MHz and is biased towards fresher injection and stronger magnetic fields. Observations made through this channel consequently appear to show a relatively laminar flow and μG-strength magnetic fields, even though this is not typical of the downstream.
