Abstract

We present computer simulations of the interaction of NGC5194 and 5195 involving the gaseous, stellar and dark matter compnonents of the two galaxies. Several observational features of NGC 5194 are reproduced using orbital parameters close to the best guess from previous calulations, including : 1) Broad stellar spiral arms 2) Narrow gaseous spiral arms with strong shock velocity discontinuities 3) A bar-like oval distortion in the central stellar bulge 4) Sharp bends in the gaseous spiral arms 5) A long southern gaseous tail 6) A dense nuclear gas ring Points (2), (3), (4) and (6) have not been reported in previous computer simulations.
