摘要
Two-dimensional kinematics of disk galaxies give valuable information on the structure and evolution of these systems, complementing-sometimes contradicting-information derived from morphological studies. We present two cases of the use of two-dimensional kinematic information to study the interacting stage of galaxies. The first case portrays an apparently isolated local galaxy. The other points out the effects that higher redshifts-and thus the lack of spatial resolution-might have on the interpretation of this type of data.
