| Abstract | The anomalous, sloping velocity shoulders on the integrated H I line profiles sometimes observed in small systems of galaxies are interpreted as evidence for ongoing tidal interactions, probably associated with galaxies in slow hyperbolic encounters in which extensive transfers of orbital to internal energy can produce extreme, noncircular motions. The identification of actively interacting galaxies and the probing of collision energetics between nonbinary galaxies can therefore be addressed by means of the kinematics of such systems. |
