From two dimensional multi-component weak-lensing analysis, we reveal that the cluster mass distribution is well described by three main components, including a two component main cluster A2163-A with mass ratio 1:8, and its cluster satellite A2163-B. The bimodal mass distribution in A2163-A is similar to the galaxy density distribution, but appears as spat","authors_text":"Herve Bourdin, Nobuhiro Okabe, Pasquale Mazzotta, Sophie Maurogordato","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2011-06-30T20:00:03Z","title":"Subaru weak-lensing study of A2163: bimodal mass structure"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1107.0004","kind":"arxiv","version":2},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:c5eed19551ee2793fb45b6d42180968a0a4129f8ed20748032e6e566b7d227fc","target":"record","created_at":"2026-05-18T02:01:26Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"7d8ad66782c7bd9eac111cafc8e25eaea8bf621d94d7214e1ecbd9592c55e983","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2011-06-30T20:00:03Z","title_canon_sha256":"ee8664b4fd7a692ae9708befb6035750b041e871bc36a35c2e76e604974973c8"},"schema_version":"1.0","source":{"id":"1107.0004","kind":"arxiv","version":2}},"canonical_sha256":"1ad0a22c7d0a8f6064a6ef1050c12d4d28d9714145aa3afb27188e073a062ef7","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1ad0a22c7d0a8f6064a6ef1050c12d4d28d9714145aa3afb27188e073a062ef7","first_computed_at":"2026-05-18T02:01:26.233170Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:01:26.233170Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"05jDYr54ZkKSTruuWTSFZgO4cxcPeS5MnoH/FxXLAI2Y4rQxkHFBik1jv89GytfuE9H3KpPOwsNJt5rrRHuzDA==","signature_status":"signed_v1","signed_at":"2026-05-18T02:01:26.233821Z","signed_message":"canonical_sha256_bytes"},"source_id":"1107.0004","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c5eed19551ee2793fb45b6d42180968a0a4129f8ed20748032e6e566b7d227fc","sha256:4fb91eaae8372d09a2fc059c5cf5f3ab4f4929bdaa4fad2ec0f74dc8e13a23b7"],"state_sha256":"c543179eba15c519e4423ab8e1fe00f5409970316825bdcdd7def0c9237da891"}
