Swinging on by: the tidal twists

Abstract

We have seen in the previous chapter that colliding ring galaxies are the result of the direct pull of the companion galaxy’s gravity as it passes through. Most galaxy “collisions” are not literally so. That is, the galaxy disks pass closely by each other, but they do not actually collide. They can still profoundly affect each other, primarily by means of forces that are analogous to those that cause ocean tides on Earth.
