Collage similar to Fig. 2 but for simulation “GRG_hp_edge” (high-powered jet propagating along the edges of the environment) showcasing the structure of the evolved GRG at the highlighted age. The dynamical age of 49 Myr is considerably low for a GRG and comparable to SRGs, hinting at the potential formation of even larger-scale GRGs within a satisfactory time frame compared to radiative ages. 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. 3.1.5.
