Dark Matter and Extragalactic Gas Clouds in the NGC 4532/DDO 137 System

Hoffman, G. L.; Lu, N. Y.; Salpeter, E. E.; Connell, B. M.

H I synthesis mapping of NGC 4532 and DDO 137, a pair of Sm galaxies on the edge of the Virgo cluster, is used to determine rotation curves for each of the galaxies and to resolve the structure and kinematics of three extragalactic H I clouds embedded in an extended envelope of diffuse HI discovered in earlier Arecibo studies of the system.
