Gas-rich galaxies in the Pegasus I cluster of galaxies. Bothun, G. D. ; Schommer, R. A. ; Sullivan, W. T., III Abstract Results of a 21-cm and optical survey of disk galaxies in the vicinity of the Pegasus I cluster of galaxies is reported, in addition to the results of a 21-cm H I and UBV photometric survey of 235 disk galaxies in nine nearby clusters. A substantial number of blue, gas-rich galaxies are revealed for the Pegasus I cluster, and with few exceptions, the disk systems in the cluster retain large amounts of neutral hydrogen, which suggests that environmental processes have not yet removed substantial amounts of gas from these disk galaxies. The analysis of 235 disk galaxies in nearby clusters indicates that most of the clusters do not preferentially contain gas deficient spirals. The large amount of H I retained by the galaxies is not well correlated with color.
