Collage similar to Fig. 2 but for simulation “GRG_lp_maj” (low-powered jet propagating along the major axis of the environment) showcasing the structure of the evolved GRG at the highlighted age. The structure has evolved to only 500 kpc on one side (∼1 Mpc in total extent) over a longer period of evolution, indicating higher jet frustration imposed by the environment while traveling along the major axis. The emerged structure is known as an X-shaped radio galaxy, and given its giant size, it is typically recognized as a GRG-XRG. Here, ρ₀ = 0.001 amu/cc, P₀ = 1.5 × 10⁻⁶ dyn/cm², and length is represented compared to L₀ = 100 kpc. Deatils are given in Sect. 3.1.3.
