Comparison of the radio luminosity profile of the simulated ORC with observations. The three coloured regions show the synchrotron power at ν = 150 MHz inferred from three different magnetic field models (see text for details). The grey band represents the result from the simulation by Dolag et al. (2023), while the horizontal dashed-dotted lines indicate the level of observed counterparts at the respective frequencies: ORC1 (Norris et al. 2022), ORC4 (Norris et al. 2021b), ORC5 (Koribalski et al. 2021), Cloverleaf (Koribalski et al. in prep.) and Physalis (Koribalski et al. 2024b). The vertical dashed lines mark the three time steps chosen for the visualisation of the merger sequence in Fig. 1.
