We present a weak-lensing analysis of A746 based on wide-field imaging data from Subaru/Hyper Suprime-Cam observations. The mass distribution is characterized by a main peak, which coincides with the center of the X-ray emission. At this main peak, we detect two extensions toward the north and west tracing the cluster galaxy and X-ray distributions. Despite the ongoing merger, our estimate of the A746 global mass M <SUB>500</SUB> = 4.4 ± 1.0 × 10<SUP>14</SUP> M <SUB>⊙</SUB> is consistent with the previous results from Sunyaev-Zel'dovich and X-ray observations. We conclude that reconciling the distributions of mass, galaxies, and intracluster medium with the double radio relic system and other radio features remains challenging....STAMPAenArticle10.3847/1538-4357/ad1bcc2-s2.0-85184923513https://iopscience.iop.org/article/10.3847/1538-4357/ad1bcchttps://api.elsevier.com/content/abstract/scopus_id/85184923513FIS/05 - ASTRONOMIA E ASTROFISICA
