Extended Data Fig. 1: Elements of the MRG0138 cluster lens model.
From: A gravitationally lensed supernova with an observable two-decade time delay
The model comprises 37 potentials in total: the BCG (red), 32 cluster members (yellow), three perturbers (cyan), and the main cluster potential (pink). Labeled × symbols indicate the positions of the SN, host, and one additional multiply imaged galaxy with a secure redshift used as model constraints (Supplemental Table 3). The filters used to generate the color image are as in Fig. 1, and tick marks are separated by 10 arcsec.
