| Abstract | In the course of a large survey of the radio and optical properties of cluster spirals, Bothun (1981) could observe a number of galaxies with peculiar characteristics. The observed galaxies contain some interacting systems which may provide important test cases in probing the role of galaxy-galaxy interactions as a mechanism of gas removal in clusters. The present investigation is concerned with some specific examples of interacting/peculiar galaxies, which are illustrated in the atlas prepared by Arp (1966). In general, the considered galaxies do not have the characteristic signatures of the violent encounters seen in small groups and described by Gallagher et al. (1981). However, their sample may be one in which the interactions are 'interpenetrating' as opposed to the grazing encounters expected to occur in clusters. With regard to the efficiency of tidal interactions as a gas removal agent, the data are rather inconclusive. |
