Most galaxies have a warped shape when they are seen from an edge-on point of view. The reason for this curious form is unknown so far. In this work, the authors apply dynamical system tools to explain it. Starting from a simple but realistic model formed by a bar and a disc, we study the eect produced by a small misalignment between the angular momentum of the system and its angular velocity. For this, a precession is applied to the bar, assuming that it behaves like a rigid body. After checkin...
