The warp of the Galaxy and the Large Magellanic Cloud

We study the possibility that the Galactic warp is caused by the tides of the Magellanic clouds. Using a specialized N-body particle+ring code we investigate the role of extra torques on the disc induced by gravitational wakes in the dark halo created by the Large Magellanic Cloud. We find that neit...

Zusammenfassung:We study the possibility that the Galactic warp is caused by the tides of the Magellanic clouds. Using a specialized N-body particle+ring code we investigate the role of extra torques on the disc induced by gravitational wakes in the dark halo created by the Large Magellanic Cloud. We find that neither the amplitude nor the orientation of the resulting warp agrees with observations.
