In galaxy clusters, most of the galaxies appear to be elliptical galaxies because O They formed in-situ from low-angular-momentum clouds O They aren't really elliptical, but they look that way because they are very distant O When galaxies collect in clusters, the proximity makes them puffier Galaxies in clusters probably had many merger events in the past
