Galaxy mergers can occur when two galaxies collide. They are the most violent type of galaxy interaction. The gravitational interactions between galaxies and the friction between the gas and dust have
The Mice Galaxies (NGC 4676 A&B) are in the process of merging.
NGC 3921 is an interacting pair of disc galaxies in the late stages of its merger.
ESO 239-2, an interacting pair of galaxies located 550 million light-years in the constellation of Grus. These galaxies are currently in the last stages of merging which the end result would be an elliptical galaxy.
