Adiabatic growth of black holes generates power-law central density profiles with logarithmic slopes in the range from ~1.5 to ~2.5, in good agreement with the profiles observed in the nuclei of galaxies fainter than visual magnitude -20. However the shallow nuclear profiles of bright galaxies require a different explanation. Binary black holes are an inevitable result of galactic mergers, and the ejection of stars by a massive binary displaces a mass of order the binary's own mass, creating a core or shallow p","authors_text":"David Merritt (Rutgers University)","cross_cats":["gr-qc"],"headline":"","license":"","primary_cat":"astro-ph","submitted_at":"2003-01-14T15:38:38Z","title":"Single and Binary Black Holes and their Influence on Nuclear Structure"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"astro-ph/0301257","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":"sha256:93265838cd6c8b01da220aae5360a29e4153a6c9aa90454e1c6bb892f36e04f9","target":"record","created_at":"2026-07-04T14:12:32Z","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":"4fde6eda76ac9dcb9d72fd7980749147f7f6cf75bab3d8f24e247cbde9974898","cross_cats_sorted":["gr-qc"],"license":"","primary_cat":"astro-ph","submitted_at":"2003-01-14T15:38:38Z","title_canon_sha256":"a7ee5e6f313134cbe950385b9c9731234b93fca629c94f50a924c7d86b47b6b5"},"schema_version":"1.0","source":{"id":"astro-ph/0301257","kind":"arxiv","version":1}},"canonical_sha256":"4c2cb572ce759d778e28bfce08c87fef8265e3d31b65d6fe84aafddfce92f80a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"4c2cb572ce759d778e28bfce08c87fef8265e3d31b65d6fe84aafddfce92f80a","first_computed_at":"2026-07-04T14:12:32.797226Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T14:12:32.797226Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"dh497OVDko8CNXi3HzhiB5BagbhJBJO87E1MEBDj9XTgCmsoC2ZlMhVOLcG3FSj2m/YllZ3H15V9yqry4gOqAA==","signature_status":"signed_v1","signed_at":"2026-07-04T14:12:32.797645Z","signed_message":"canonical_sha256_bytes"},"source_id":"astro-ph/0301257","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:93265838cd6c8b01da220aae5360a29e4153a6c9aa90454e1c6bb892f36e04f9","sha256:903efbcda3e661de4f032451ea21100fe5c3d7e6ee2505ea3e8674585d3c5c78"],"state_sha256":"7a5cc32c173de7fdcf2593d5010b386193fd46444feb3d380a92db744a18d71c"}
