This phenomena was first discovered in 1986 by Lynds and Petrosian: magnified, distorted and strongly elongated images of background galaxies which happened to lie behind foreground clusters of galaxies. Clusters of galaxies at Z ≈ 0.2 with masses of order 1014 M¯ are very effective lenses. Their Ei ...
