We discuss the observational properties of a remarkably faint triply imaged galaxy revealed in a deep z'-band Advanced Camera for Surveys observation of the lensing cluster A2218 (z = 0.175). A well-constrained mass model for the cluster, which incorporates the outcome of recent Keck spectroscopic campaigns, suggests that the triple system arises via a high-redshift (z > 6) source viewed at high magnification (25 times). Optical and infrared photometry from Hubble Space Telescope and the Keck… CONTINUE READING
