Gas stripping from spirals within X-ray clusters of galaxies.
Abstract
Summary. Empirical evidence is presented supporting the process of gas stripping from spirals by a hot intergalactic medium in clusters. Using deep photographic plates taken in excellent seeing by the UK Schmidt Telescope Unit at Siding Spring, galaxies within five southern X-ray clusters were morphologically classified. The new data are combined with pre-existing data to show a strong correlation betweefl the percentage of (E + SO) galaxies and the cluster X-ray luminosity. On the basis of this correlation and some other new criteria, the optical identification of 3U 1252 -28 with an individual galaxy (rather than the cluster core) is suggested.
