This is based on a new concept, the photometric mass function (PMF), which opens up the possibility of an efficient identification of dynamical BHs in large fields-of-view. This exploits the width of the disc Halpha emission line, combined with orbital period information. We here show that Halpha widths can be recovered using a combination of customized Halpha filters. By setting a width cut-off at 2200 km/s we are able to cleanly remove other Galactic populations of Halpha emitters, including ~99.9%","authors_text":"Jorge Casares","cross_cats":["astro-ph.GA","astro-ph.HE"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.SR","submitted_at":"2017-11-09T19:00:01Z","title":"Hibernating black holes revealed by photometric mass functions"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1711.03553","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":"sha256:991b998ad8f5053944eda2c77e4b1098923e2050da67dd06da22958390d87e63","target":"record","created_at":"2026-05-18T00:28:10Z","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":"fec0db14aa0f91310a3125c5bdd15d6cfab9f74198dc14aff1ed0209526f0f7a","cross_cats_sorted":["astro-ph.GA","astro-ph.HE"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.SR","submitted_at":"2017-11-09T19:00:01Z","title_canon_sha256":"63659fbc69a6bc28268b7dad48a19e8def4320cbb5f4cfd4b48c1e95163253e9"},"schema_version":"1.0","source":{"id":"1711.03553","kind":"arxiv","version":1}},"canonical_sha256":"249bf655ae64f00e78fa81fac1ece0cc7d2517e37ec31bec9abfec01d35e0d44","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"249bf655ae64f00e78fa81fac1ece0cc7d2517e37ec31bec9abfec01d35e0d44","first_computed_at":"2026-05-18T00:28:10.384984Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:28:10.384984Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"7BK428I1M6plrKlV/36fvq/wl0nchxkPxE4MMn4xUTDJ/pEGesRL4VPeOCSw/2/TtHI90THZUxVjRTbr4w12Ag==","signature_status":"signed_v1","signed_at":"2026-05-18T00:28:10.385769Z","signed_message":"canonical_sha256_bytes"},"source_id":"1711.03553","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:991b998ad8f5053944eda2c77e4b1098923e2050da67dd06da22958390d87e63","sha256:4f1d270ab1e7339876c49606eb4c35a9be0232a11e1eadb7b895b2384000c449"],"state_sha256":"9383d14ba117b31a1c04ec08d8ead2a146bf229df6e635c81e1ac8fd3d88fcca"}
