Gas stripping in galaxy clusters: a new SPH simulation approach
P.Jáchym, J.Palouš J.Köppen, F.Combes
ABSTRACT We present the results of numerical simulations of gas stripping in clusters, using N-body and SPH techniques adapted for two different gas phases, the diffuse and hot ICM and the denser and colder ISM. We compare the stripping efficiency with analytical approximations and with Gunn & Gott (1972) formula. Early and late type galaxies in large or small galaxy clusters show different stripping efficiencies, reaccretions and final masses dependent on the duration of the interaction. We discuss the origin of ICM and its large metallicity.
