Neutral hydrogen observations at the VLA.
Abstract
A survey of the neutral hydrogen line emission from bright spiral galaxies in the Virgo cluster has been done using the Very Large Array (VLA). The first results on 10 of the brightest spirals close to the cluster centre have been presented previously (van Gorkom et al., 1984). They show that the H I disks of spirals within a radius of about 3° from M87 are anomalously small, those outside being normal. The change occurs rather sharply at that radius, suggesting that the dominant mechanism is ram-pressure stripping of the interstellar gas by the diffuse halo of M87. Here the authors present preliminary data for the full sample, which is nearly complete to a limiting optical magnitude.
