The BBH merger event rate is estimated based on a set of 65 state-of-the-art evolutionary models of star clusters, as presented in Banerjee (2021). These relativistic direct many-body computed models incorporate up-to-date stellar mass loss and remnant formation ingredients. The merger-event rates are obtained by constructing a cluster population of the Universe, out of the models, taking into account ma","authors_text":"Sambaran Banerjee","cross_cats":["astro-ph.GA"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2020-11-13T16:31:17Z","title":"Stellar-mass black holes in young massive and open stellar clusters V: comparisons with LIGO-Virgo merger rate densities"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2011.07000","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:ca6cfcd9af71798066a1bff539acc35a37e59dee2ff028236d853be735704fa1","target":"record","created_at":"2026-07-05T02:23:18Z","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":"c34aa633fcb3801de42dff5fdcafa7d013fa7c32199107bb1659af740a7943af","cross_cats_sorted":["astro-ph.GA"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2020-11-13T16:31:17Z","title_canon_sha256":"50c54f55d96e75f3933afde193572d60dd44c7b06bfd43d3c209fc9ff0c85a5a"},"schema_version":"1.0","source":{"id":"2011.07000","kind":"arxiv","version":2}},"canonical_sha256":"95a6096dd00e597ae19db5d97ec73a125ee05cd95c0157dd6b56bd2064a734c0","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"95a6096dd00e597ae19db5d97ec73a125ee05cd95c0157dd6b56bd2064a734c0","first_computed_at":"2026-07-05T02:23:18.357609Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T02:23:18.357609Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"YeIMwoMLDbGByOQe9cQqD1VbJvujxmc5SU4Y/BaliDBYoVaKZc6liqD5Dctw82lCr2J49M1qfW8YzBEehdU6Dg==","signature_status":"signed_v1","signed_at":"2026-07-05T02:23:18.358086Z","signed_message":"canonical_sha256_bytes"},"source_id":"2011.07000","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ca6cfcd9af71798066a1bff539acc35a37e59dee2ff028236d853be735704fa1","sha256:ff15350fc67318ec2422fbc87e7b24764534861d67dce174073a893b5fc5b224"],"state_sha256":"0d08b65006925aa01d270ec4995e44449cd301645176d53a488b594ac480cb0c"}
