Spherical lens Einstein ring Elongated lens Einstein cross Lens = cluster Arcs and arclets Abbell 2218 cluster
Mass map of galaxy cluster Cl0024+1654 • Superposition of 2 images • Blue = dark matter map • Light = luminous matter map • Red dots = galaxies in cluster • HST and ground based observations + mass mapping models • Dark matter is present where galaxies clump together = ‘glue’
