摘要：We summarize results from an H I+optical imaging study of the “Integral Sign” galaxy,
UGC 3697. UGC 3697 is a low-mass, Sd spiral that exhibits a “superthin” disk morphology
despite a prounced gasous and stellar warp. Our new observations show evidence for a recent
minor merger in this system that could account for its large-scale warp and a number of other
properties of this galaxy. We speculate that UGC 3697 has been caught in a rather short-lived
dynamical state, and may soon undergo significant structural and morphological changes.
