Morphological collage similar to Fig. 2 but for simulation “GRG_hp_min” (high-powered jet propagating along the minor axis of the environment) showcasing the structure of the evolved GRG at the highlighted age. We emphasize the much shorter evolution time for the jet to reach ∼700 kpc compared to the low-powered jet along the minor axis. Here, ρ₀ = 0.001 amu/cc, P₀ = 1.5 × 10⁻⁶ dyn/cm², and length is represented compared to L₀ = 100 kpc. Details are given in Sect. 3.1.2.
