Illustration of the increased resolution between HORIZON-AGN (upper row) and OBELISK (lower row) for the projected gas density (first two columns) and typical cell size (last two columns). The first and third columns highlight the large-scale environment, where the resolution in the filaments goes from Δx_{H ORIZON−AGN} ∼ 4 kpc to ΔxO BELISK ≲ 500 pc, and the second and fourth columns shows the improvement at the galaxy scale.
