It is now known that at least some NSCs coexist with supermassive black holes (SBHs); this is the case, for instance, in the Milky Way (MW). In this paper, we investigate how the presence of a SMBH at the center of the MW impacts the merger hypothesis for the formation of its NSC. Starting from a model consisting of a low-density nuclear stellar disk and the SMBH, we use N-body simulations to follow the successive","authors_text":"Alessandra Mastrobuono-Battisti, David Merritt, Fabio Antonini, Roberto Capuzzo-Dolcetta","cross_cats":["astro-ph.CO"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.GA","submitted_at":"2011-10-26T22:05:06Z","title":"Dissipationless Formation and Evolution of the Milky Way Nuclear Star Cluster"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1110.5937","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":"sha256:3c74f4182ace9d4501139454b726147238f5b7c6cfca09ccabf72427618cb2b7","target":"record","created_at":"2026-05-18T02:00:03Z","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":"f4eea58d84772393b118c68744576ec54e1f65dca9a2e2230b49566b8476741a","cross_cats_sorted":["astro-ph.CO"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.GA","submitted_at":"2011-10-26T22:05:06Z","title_canon_sha256":"f0e8594193d344877647c933690f80a2f3370e237d3cbb040a3017bc22d654b7"},"schema_version":"1.0","source":{"id":"1110.5937","kind":"arxiv","version":2}},"canonical_sha256":"2c28bb87f450697320e790c24143813c38a4b210f3d19aaf6fa141b5667673d1","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2c28bb87f450697320e790c24143813c38a4b210f3d19aaf6fa141b5667673d1","first_computed_at":"2026-05-18T02:00:03.339549Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:00:03.339549Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"vj6pqwKFH28jgqoEfO8Ua2Lk6CCZEeSD+jmACZ9AKm0Cmja32z/F92nSYpj4xo78QiR8fPjBU4Mmf0FbpOe3DQ==","signature_status":"signed_v1","signed_at":"2026-05-18T02:00:03.340058Z","signed_message":"canonical_sha256_bytes"},"source_id":"1110.5937","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:3c74f4182ace9d4501139454b726147238f5b7c6cfca09ccabf72427618cb2b7","sha256:40f1e85185c3672ded4d7bcda1fa00988ca36e7c7630358f879b5f1526e49561"],"state_sha256":"89b373c9ffc103c2d80fd378036527a04e93e5f1c540d6dfa9724762a31f05e0"}
