Because these high-convergence regions are directly related to the physical nonlinear structures of the universe, they derive cosmological information mainly from the nonlinear regime of density fluctuations. We show that in combination with future cosmic microwave background anisotropy measurements, this method can place constraints on cosmological parameters that are comparable to those fr","authors_text":"Morgan May, Sheng Wang, Zolt\\'an Haiman","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph","submitted_at":"2008-09-24T02:06:43Z","title":"Constraining Cosmology with High Convergence Regions in Weak Lensing Surveys"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0809.4052","kind":"arxiv","version":1},"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":"sha256:307e61d27ba082041842f54ba8734b8493988206bd606c7b87cee372745de081","target":"record","created_at":"2026-05-18T04:29:26Z","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":"3dc8f4bb6b7fa3ed9e5b5b019a5b840e8b220b041e76acbc9ec00d62e4c8451c","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph","submitted_at":"2008-09-24T02:06:43Z","title_canon_sha256":"0710e8c353cc90ccc2f42f12bf147c56c2f839403e5330ea8f628c01faed04d8"},"schema_version":"1.0","source":{"id":"0809.4052","kind":"arxiv","version":1}},"canonical_sha256":"31b3ea0e853bbe60188a2b484cda58a9cf307e7106c563f5a2b320cee4570d00","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"31b3ea0e853bbe60188a2b484cda58a9cf307e7106c563f5a2b320cee4570d00","first_computed_at":"2026-05-18T04:29:26.515844Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T04:29:26.515844Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"KL2Hg+wyEfHemGl+1Yrs0XE2lRuMC+m7eEDZn98uodQ5OFAWE817t+wtVMu5dZRxGu5fy2c069QLX5538xZMBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T04:29:26.516229Z","signed_message":"canonical_sha256_bytes"},"source_id":"0809.4052","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:307e61d27ba082041842f54ba8734b8493988206bd606c7b87cee372745de081","sha256:a45da1f450d77c411a03361717acd154badc67649319aa354f63cdee5c7bf316"],"state_sha256":"0b6363981f3206bbcd4019681be4edb13ec0f6d8bd360fd0d58e5d8068cd5a0c"}
