VIVA The Virgo Cluster HI Survey is a project to image in HI at 15" resolution (in the C array configuration) 28 carefully chosen spiral or spiral-like Virgo cluster galaxies. When combined with already existing or scheduled VLA observations this will make a total sample of 40 galaxies. These 40 systems cover a factor of 20 in mass, and they are located throughout the cluster, from the dense core to the low density outer parts. They span a range in star formation properties from anemic to starburst. They contain undisturbed and interacting galaxies, and include the best candidates for strong ISM-ICM interactions. With this sample we hope to study in detail the various physical mechanisms that are thought to drive the evolution of galaxies in clusters at intermediate z. The data will also be used to constrain hydrodynamical simulations, which have only become available in recent years.
