Abstract
We study the morphological changes induced by the Intra Cluster Medium (ICM) on spiral galaxies when they move through the core cluster. The galaxies are modeled as a thin exponential slab of cold gas, a stellar disk, bulge, and dark matter halo. The interaction of galaxy with the ICM is studied by means of a 3-dimensional non-symmetric high-resolution hydrodynamic code for gaseous matter, coupled with a N-body code for the collision-less matter. Several parameter ranging reasonable values for ICM and galaxies have been considered. We conclude that, for some scenarios compatible with observations, ram-pressure stripping could suffice to explain the Butcher—Oemler effect and the morphologic transformation of spiral galaxies in lenticulars (S0).
