Here, we present direct $N-$body simulations of two different star cluster families: low-mass ($\\sim{500-800}$ M$_\\odot$) and relatively high-mass star clusters ($\\ge{5000}$ M$_\\odot$). We show that the formation channels of BBHs in low- and high-mass star clusters are extremely different and lead to two completely distinct populations of BBH mergers. Low-mass clusters host mainly low-mass BBHs born from binary evolution, while BBHs in high-mass clusters are r","authors_text":"Alessandro Ballone, Mario Pasquato, Michela Mapelli, Sara Rastello, Stefano Torniamenti, Ugo N. di Carlo","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.GA","submitted_at":"2022-03-15T18:00:02Z","title":"Dynamics of binary black holes in young star clusters: the impact of cluster mass and long-term evolution"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2203.08163","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":"sha256:698445d5bae278987da69152519a356cefe3819c2e0318d35f399c5bfa796d3d","target":"record","created_at":"2026-07-05T05:05:32Z","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":"d135f7e55bcd7965d9431c224480b15bdaf63b5ef088d503ac7b1bb101b87af3","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.GA","submitted_at":"2022-03-15T18:00:02Z","title_canon_sha256":"b1c5ec887dbde2d83bb07f4a2932ee0576042bd622632db9a55a1e9dccd0bcd8"},"schema_version":"1.0","source":{"id":"2203.08163","kind":"arxiv","version":2}},"canonical_sha256":"80350cee899f0369bc49aff36d348b9d03c57696e85593b194e13a1821e77b4d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"80350cee899f0369bc49aff36d348b9d03c57696e85593b194e13a1821e77b4d","first_computed_at":"2026-07-05T05:05:32.050081Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T05:05:32.050081Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"DChsPqjn1f2ZY2LNZjkV17t7DvSIrRUwjBpp7V+u3ekht+hctZ5aacAZz+Jf98pjziZq/4yeM+9iSMzIBQziCw==","signature_status":"signed_v1","signed_at":"2026-07-05T05:05:32.050567Z","signed_message":"canonical_sha256_bytes"},"source_id":"2203.08163","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:698445d5bae278987da69152519a356cefe3819c2e0318d35f399c5bfa796d3d","sha256:76b050f04573d625c78024805a469129d92b2013766cea04cdff5c2a0100d58e"],"state_sha256":"7c3a142ba3a50c4f0549a7ccd512296e6bb6d37e64d009b82c7d23717567714c"}
