Scientific paper

The dynamics of the Coma cluster are probed through the study of spiral galaxies that have been stripped of gas and ellipticals that have been tidally stripped. Since such stripping is most effective in regions where intergalaxy or cluster gas density is highest, the affected galaxies probably have orbits that take them through the center of the cluster. The Bothun et al. (1982, 1983) data analyzed indicate that the spirals in the cluster center are deficient in H I relative to other spiral members. Observations by Strom and Strom (1978) may indicate the tidal stripping of elliptical galaxies near the cluster center. For both data sets, the most likely models are everywhere isotropic.
