C. Continued. Intensity map (log I_ν) at 1 GHz radio frequency revealing an intriguing case where the jet flows with minimal hindrance due to its propagation along the edges of the surrounding environment (“GRG_hp_edge”). The faster propagation causes increased shear between the cocoon and the environment as well as between the jet spine and sheath layers and results in the generation of instabilities, leading to the formation of pronounced turbulent structures at 49 Myr.
