For this purpose, we use the Spin-Modified Fundamental Plane of black hole activity, which non-linearly connects the following four variables (in the source frame): radio luminosity, X-ray or optical luminosity (via the [OIII] emission line), black hole mass and spin. Taking into account the uncertainties in luminosity measurements, conversion factors, relativistic beaming and physical properties of the AGN system, we derive lower ","authors_text":"Abraham Loeb, Caner Unal, Fabio Pacucci","cross_cats":["astro-ph.CO","astro-ph.HE","gr-qc","hep-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2020-12-23T16:47:37Z","title":"Properties of Ultralight Bosons from Spins of Heavy Quasars via Superradiance"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2012.12790","kind":"arxiv","version":5},"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:ec12b6e95b42b7bf593841763671535ab924e1ddc8f0d59520a8d97e86578bfb","target":"record","created_at":"2026-07-05T10:30:50Z","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":"e190863f6abdbd4c8df2a72529accb99504a817cac2887283359cc6f348dba04","cross_cats_sorted":["astro-ph.CO","astro-ph.HE","gr-qc","hep-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"hep-ph","submitted_at":"2020-12-23T16:47:37Z","title_canon_sha256":"b09c14c560feba3136a53efc96490fbab6cf0105485f1f8813e7e02e7621d92a"},"schema_version":"1.0","source":{"id":"2012.12790","kind":"arxiv","version":5}},"canonical_sha256":"ce7089c15ed5d2863f0c3e7ae219f2d9f3e0cbbfe023402066795f19c38d20f5","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ce7089c15ed5d2863f0c3e7ae219f2d9f3e0cbbfe023402066795f19c38d20f5","first_computed_at":"2026-07-05T10:30:50.095293Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:30:50.095293Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"d2zwSZIMOyrzuLtq2Eqr36LRkBkXY6ubGAr5FE1ost9dvNVpCASa+vB17JJTFSAIibMhL2geHKppwresMkOLDw==","signature_status":"signed_v1","signed_at":"2026-07-05T10:30:50.095997Z","signed_message":"canonical_sha256_bytes"},"source_id":"2012.12790","source_kind":"arxiv","source_version":5}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ec12b6e95b42b7bf593841763671535ab924e1ddc8f0d59520a8d97e86578bfb","sha256:bcdb4fdb23ac7a57be670b673f41354a6d5614f470f56847cbf8cd5f2df8adc8"],"state_sha256":"8f86914808a626ed786a2c0bebdb9126663dc9ffd1333498840269b5b15a0b4f"}
