Abstract
The intracluster medium (ICM) in galaxy clusters contains heavy elements with about 1/3 of the solar abundance. These heavy elements are the products of stellar nucleosynthesis and are either expelled by galactic winds or lost from the galaxies due to interactions with the intracluster gas. We investigate the stripping of hot, high-metallicity galactic halos, which occurs as galaxies are moving through a cluster, being subject to the ram pressure of the ICM. Our new model for ram pressure stripping differs from earlier models, since it includes processes inside the galaxies like the transport of gas from the disk into the halo. Taking into account different components of the interstellar medium and their vertical distribution, we get a more realistic and detailed stripping criterion.
