Column density of the cold gas, T < 5 × 10⁴ K, projected on a plane parallel to the jet axis, for various snapshots ranged in less than 1 Gyr (from left to right), of the five runs K1, K05, K05_np, K01, and K01_np (from top to bottom). The figure shows the crucial differences in the cold gas formation: run K1 shows the most prominent cold gas structures in a filamentary and clumpy form. Run K05 shows the presence of a long-lived cold gas disk, with very rare formation events of few clumps. While run K05_np forms less cold gas compared to runs with precession, it shows a spatially large distribution of cold structures, similar to run K1. Runs K05 and K05_np have cold gas structures more localized in the center, with the former, with precession, having more cold gas.
