Both animations below show the response of the halo and vertical distortion of the disk to the satellite. The satellite is played by a small yellow sphere and its orbit is a tube. The tube varies from red at pericenter to blue at apocenter. The satellite mass is scaled to the large LMC value. The disk height is exaggerated by a factor of two and color coded from blue (negative height) to red (positive height). The halo wake is shown using constant value isosurface of negative (blue) to positive (red) overdensity. The value is chosen to best depict the evolution. The enclosing box is 140 kpc on a side.
This first animation shows the halo wake including all harmonics while the second animation only shows the l=m=2 contributions. Finally, for those so equiped, a VRML of one frame from the second animation is provided.
