clusters in the RELICS program. We find that they exhibit similar stronglensing efficiencies to the clusters targeted by the Hubble Frontier Fields within the WFC3/IR field of view. Outputs of the … Here, we present stronglensmodels for fiveclusters from the first set of RELICS Cycle 24 observations. We describe the sample selection in Section 2, and the HST imaging and ground-based spectroscopy follow-up in Section 3. We then describe the …
Abstract
Strong gravitational lensing by galaxy clusters magnifies background galaxies, enhancing our ability to discover statistically significant samples of galaxies at
