RELICS: Strong Lens Models for Five Galaxy Clusters From the Reionization Lensing Cluster Survey Academic Article uri icon


  • Abstract: Strong gravitational lensing by galaxy clusters magnifies background galaxies, enhancing our ability to discover statistically-significant samples of galaxies at z> 6, in order to constrain the high-redshift galaxy luminosity functions. Here, we present the first five lens models out of the Reionization Lensing Cluster Survey (RELICS) Hubble Treasury Program, based on new HST WFC3/IR and ACS imaging of the clusters RXC J0142. 9+ 4438, Abell 2537, Abell 2163, RXC J2211. 7-0349, and ACT-CLJ0102-49151. The derived lensing …
