Synthetic synchrotron flux maps in the radio (ν = 3 × 10¹¹ Hz, left) and in the optical band (ν = 5 × 10¹⁴ Hz, right) from simulations shown in Figure 1. We display the results for the two stellar distributions r_c,s = 1.0 kpc (up) and r_c,s= 1.5 kpc (down) for a viewing angle θ_obs = 10°, a redshift z = 1.4, a fixed $r_{\mathrm{c}}=1.0\mathrm{kpc},$ and a fixed average mass load of Q₀ = 5 × 10²³ g · yr⁻¹ · pc⁻³.
