Ram pressure profiles in galaxy groups and clusters

Using a hybrid method that combines non-radiative hydrodynamical simulations with a semi-analytic model of galaxy formation, we determine the ram pressure experienced by galaxies in haloes with virial masses 12.5 ≤ log(M 200/h -1M ⊙) < 15.35 as a function of the halocentric distance, for reds...
