  "abstract": "Semi-analytic models of galaxy formation typically form the spheroidal components of galaxies (\"bulges\"), solely through galactic major mergers. However, it is possible that non-merger events (e.g. a \"fly-by\" by a smaller halo) can perturb a galaxy--halo system sufficiently to form a bulge. We present a preliminary investigation into the frequency of major changes in halo and galaxy spin direction, which could be signatures of such events.",
