ESO 146-5
ESO 146-5 (ESO 146-IG 005) is the designation given to a group of interacting giant elliptical galaxies in the center of the Abell 3827 cluster. The group is well noted due to their strong gravitational lensing effect. ==Physical characteristics== This group of interacting galaxies was found 1.4 billion light years away in the center of Abell 3827. A huge halo of stars is surrounding their interacting nuclei. The group has immense gravity that holds the cluster together due to its mass. The group's unusual shape has led to the conclusion that each one of the nuclei were formed from multiple collisions of smaller galaxies, and now the nuclei are merging to form a single huge elliptical galaxy.
