The galaxy Arp 147 belongs to a class of objects believed to have formed a ring as a result of a collision with a second galaxy. We have produced a combined stellar and gasdynamical computer model of a pair of interacting galaxies which exhibits many of the features seen in Arp 147. In our model, the ring forms in a disk galaxy following the passage of an equal-mass elliptical galaxy approximately perpendicular through the disk, about two radial scale lengths from the center. Some generic features of this type of collision are that (1) 'hot spots' of increased gas density and shocks occur on opposite sides of the ring, away from the nucleus; (2) an incomplete ring forms, with the disk galaxy's remnant nucleus offset from the center and no longer in the plane of the disk; and (3) this nucleus can appear buried in one edge of the ring depending on the orientation relative to the observer.
