Density slices perpendicular (first and second row, zoomed by a factor of 10) and parallel (third and fourth row, zoomed by a factor of 5) to the disk plane, at t ≈ 50 kyr. Streamlines corresponding to magnetic field lines and arrows corresponding to the velocity field are overplotted. Columns from left to right: Runs NOTURB, SUPA, SUPAS, and SUBA. The mass density ρ = 10⁻¹⁹ g cm⁻³ corresponds to the particle density n = 2.6 × 10⁴ cm⁻³ and ρ = 10⁻¹¹ g cm⁻³ to n = 2.6 × 10¹² cm⁻³. White dots represent sink particles.
