A. Intensity maps (log I_ν) at 1 GHz radio frequency for two simulation cases: a low-power jet (“GRG_lp_min”; top) and a high-power jet (“GRG_hp_min”; bottom). Both jets are propagating along the minor axis of the ambient medium. While the overall structures resemble the dynamical maps from Paper I, the emission maps offer deeper insights, highlighting crucial aspects of the observability of these simulated giant radio structures at their evolved stages (∼167 Myr: top; ∼69 Myr: bottom).
