Thin slices of the dark matter density field from the first S¹ × ℝ² StePS simulation at z = 11, z = 3, and z = 0 redshifts in comoving coordinates. Each slice has a thickness of 15.0 Mpc and each column shows a different slice orientation. The late-time non-linear cosmic web is visually similar to that found in T³ and ℝ³ simulations: voids, walls, filaments, and dark matter halos are clearly visible. Due to the zoom-in nature of the StePS S¹ × ℝ² simulation method, the spatial resolution is highest along the central axis, while only the largest structures are resolved near the R_sim simulation radius.
