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_500_=4.4+/-1.0x10^14^M_{sun}_ 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.2024ApJ...962..100Hhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/962/100CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toV/154 : Sloan Digital Sky Surveys (SDSS), Release 16 (DR16) (Ahumada+, 2020)J/ApJ/805/143 : MC2: redshift analysis of CIZA J2242.8+5301 (Dawson+, 2015)J/A+A/594/A27 : Planck Sunyaev-Zeldovich sources (PSZ2) (Planck+, 2016)J/ApJ/838/110 : Spectroscopic survey of ZwCl 0008.8+5215 (Golovich+, 2017)J/ApJS/240/39 : Merging galaxy cluster deep observations (Golovich+, 2019)J/ApJ/882/69 : Radio relic merging cluster substructures (Golovich+, 2019)J/A+A/660/A78 : LoTSS-DR2 sample overview release (Botteon+, 2022)J/ApJ/925/68 : Spectroscopic redshift catalog of the A1240 field (Cho+, 2022)J/ApJS/258/11 : The COSMOS2020 catalog (Weaver+, 2022)J/A+A/680/A31 : Radio relics in LoTSS-DR2 and PSZ2 (Jones+, 2023)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/962/100https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/962/100http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/962/100https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/962/100https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/962/100http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/962/100GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/962/100/table1 (Spectroscopic redshift catalog of galaxies in the A746 field)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/962/100/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/962/100/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/962/100/table1?GETtext/xml+votable180.050000true137.224018651.474218590.0055555555555555566/7221 7223 7264https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/962/100?format=asciiOpticaldefaultJ/ApJ/962/100/table1Spectroscopic redshift catalog of galaxies in the A746 fieldrecnoRecord number assigned by the VizieR team.
