Discovery of a Strongly Lensed Galaxy at<i>z</i>=3.9 behind a<i>z</i>=0.83 Galaxy Cluster
We report on the discovery and spectroscopic confirmation of three gravitationally-lensed images of a galaxy at $z=3.9$ in the background of a distant, rich cluster of galaxies at $z=0.83$, on the basis of observations with Faint Object Camera And Spectrograph on the Subaru telescope. We construct a simple lens model …
