Collage similar to Fig. 2 but for simulation “GRG_hp_maj” (high-powered jet propagating along the major axis of the environment) showcasing the structure of the evolved GRG at the highlighted age. This morphology exhibits the formation of a mini-wing perpendicular to the active lobe. Additionally, it demonstrates the phenomenon of rapid jet propagation (top-hat jet front), leaving the cocoon behind at the given time. Such topology are not uncommon for GRGs and have been observed in many instances. 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. 3.1.4.
