Ram Pressure Stripping in the Virgo Cluster

  • Bernd Vollmer
Part of the Astrophysics and Space Science Proceedings book series (ASSSP)

The recent advances in understanding the effects of ram pressure on Virgo spiral galaxies is discussed. For a sample of 6 galaxies interaction diagnostics are made by a detailed comparison between observed and simulated gas distributions and velocity fields. Once the interaction is identified (gravitational, ram pressure or a mixture of both), we can estimate its parameters. The importance of a new diagnostic tool, the polarized radio continuum emission, is emphasized. This emission shows a characteristic distribution in cluster spiral galaxies. It directly traces gas compression or shear regions, which both can occur during an interaction of a cluster galaxy with its environment. A first complete time sequence for ram pressure stripping in the Virgo cluster is presented.
