A small fraction of these mergers are detected as individually resolvable gravitational-wave events by advanced detectors such as LIGO and Virgo. The rest contribute to a stochastic background. We derive the statistically optimal search strategy for a background of unresolved binaries. Our method applies Bayesian parameter estimation to all available data. Using Monte Carlo simulations, we demonstrate that the search is both \"safe\" and effective: it is not fooled by instrumental artefacts such as gl","authors_text":"Eric Thrane, Rory Smith","cross_cats":["astro-ph.HE","astro-ph.IM"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2017-12-03T00:55:35Z","title":"The optimal search for an astrophysical gravitational-wave background"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1712.00688","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":"sha256:1e90b3abc94d384cabb499cb73a67d8775fbea03614e9fa133067e266c6ece2f","target":"record","created_at":"2026-05-18T00:17:42Z","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":"33da676a9cf642ffc216bf8b948b7cf76200e9f5c2ede237f13eb595a47f82bc","cross_cats_sorted":["astro-ph.HE","astro-ph.IM"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2017-12-03T00:55:35Z","title_canon_sha256":"cb102ab2f9836410e11b57d28317a6bf9dced7a5ce20ead0a27952ee9f108a6b"},"schema_version":"1.0","source":{"id":"1712.00688","kind":"arxiv","version":2}},"canonical_sha256":"06e973c2b072e5e086b20c1234b5c1d9757285e1682464d4ddc4d9c6d4134950","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"06e973c2b072e5e086b20c1234b5c1d9757285e1682464d4ddc4d9c6d4134950","first_computed_at":"2026-05-18T00:17:42.030768Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:17:42.030768Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"R4Dzu9pL4MLQX3Ykvrc5X9ZJUafk3I+kMPsxzdcKxXmnZC9xEEE6ukcI1/miI1Bscw78xW0hXYQ1fS5HE5BACg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:17:42.031456Z","signed_message":"canonical_sha256_bytes"},"source_id":"1712.00688","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1e90b3abc94d384cabb499cb73a67d8775fbea03614e9fa133067e266c6ece2f","sha256:07b95b28859f97b3b686a92a8f5f8a3086a71d311af1c6a79a7e479f067265e9"],"state_sha256":"a189605b7865bc3a6c2055181bfc6c8e9315d56ad1b5957734612181ad1befe1"}
