(via Gravitational lens reveals details of distant, ancient galaxy | UChicago News) I’ve been wondering when someone would start to do this. Cosmologists at UChicago have taken VLT data, Hubble Wide-Field 3 data, and some serious computer modeling and optics/relativity reverse-engineering to use a galaxy cluster’s gravitational lensing effect as a telescope. The reconstructed galaxy at the lower-left is based on the relativistic warping created by the foreground galaxy cluster on the circled warped and repeated images of the galaxy itself, which is actually behind the cluster.
