Top panels: slices of 1 kpc through the centre of the Virgo run HR, showing the radial component of the turbulent velocity field (left, in [km s^-1]) and the tangential one (right, in [km s^-1]). Bottom panels: volume-averaged maps of turbulent velocity field (im [km s^-1]) for a line of sight of 200 kpc in run HR (left panel) and maps of turbulent diffusion for a slab of 20 kpc (right, in units of [cm²   s^-1]). Each image has sides 400    ×    500 kpc.
