Gas sloshing in the VIRGO cluster, triggered by a minor merger (Roediger et al. 2011). The images are slices through the centre of the simulation box, showing the absolute value of the total (top panels) and turbulent (lower panels) velocity for the three different resolutions: 2 kpc (LR), 1 kpc (MR) and 0.5 kpc (HR). The colour coding is in [km   s^-1], each image has sides  ~250    ×    300 kpc.
