Abstract: We present a series of hundreds of collisionless simulations of galaxy group mergers. These simulations are designed to test whether properties of elliptical galaxies — including the key fundamental plane scaling relation, morphology and kinematics — can be simultaneously reproduced by dry multiple mergers in galaxy groups. Preliminary results indicate that galaxy group mergers can produce central ellipticals lying on a tilted fundamental plane, even without a dissipational component or starburst. This suggests that multiple mergers in groups are an alternate avenue for the formation of elliptical galaxies which could well dominate for luminous ellipticals.
