Abstract

Abstract We present a parametric strong-lensing model for the galaxy cluster MACS J1931.8-2635 ( z l = 0.35), accompanying the detection of the spectroscopically confirmed SN Eos at z = 5.13. We identify 10 new multiple-image systems in recent VENUS JWST/NIRCam imaging, so that the model is constrained with a total of 19 robust multiple-image systems—nine of which also have a spectroscopic redshift. For the point-like source corresponding to SN Eos, our model predicts a total of five images, with the observed radial image pair having a similar magnification of μ ≃ 25–30 and a small time delay of
