Phase-space slice of ‘CDM’ halos. Halos 1, 2, and 3 are examined in the first, second, and third column of panels, respectively. From top to bottom: Vlasov runs with increasing force resolution are considered, with n_g = 128 (VLA-CDM12.5-LR in the left two panels and VLA-CDM25-LR in the right one), 256 (VLA-CDM12.5-MR and VLA-CDM25-MR), and 512 (VLA-CDM12.5-HR and VLA-CDM25-HR), then PM simulations with n_g = 512 (PM-CDM12.5-HR and PM-CDM25-HR). In the last case a very thin slice of particles having (y, z) ∈ [−Δ/2, Δ/2] is represented, with Δ = 10⁻³L and 4 × 10⁻³L respectively in the fourth and fifth row of panels.
