A precise measurement of $f_{\\mathrm{NL}}$ is difficult because the effects of non-Gaussianity mostly arise on the largest scales, which are heavily affected by the low statistical sampling commonly referred to as cosmic variance. The multi-tracer approach suppresses cosmic variance and we implement it by combining the information from next-generation galaxy surveys in the optical/near-infrared band and","authors_text":"Matilde Barberi Squarotti, Roy Maartens, Stefano Camera","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2023-06-30T18:00:10Z","title":"Radio-optical synergies at high redshift to constrain primordial non-Gaussianity"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2307.00058","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":"sha256:16f93936cea493c9bc3658e55148082a9d6bec4c097f4f2ada0ae4f920645613","target":"record","created_at":"2026-07-05T07:49:32Z","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":"10d6cc0f6027bb07af52a64ed9d7dfdd8d32e55f89a21b428d0936f5ea80f32d","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2023-06-30T18:00:10Z","title_canon_sha256":"cba371f48da8fe3015edde3fe9af05a4a804e59fbf3646823a2bdd9cd0a3b355"},"schema_version":"1.0","source":{"id":"2307.00058","kind":"arxiv","version":2}},"canonical_sha256":"58ad055bd917fc081935fb446b6cbe7e3b4a0303e18ca672f04550fed7f96e31","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"58ad055bd917fc081935fb446b6cbe7e3b4a0303e18ca672f04550fed7f96e31","first_computed_at":"2026-07-05T07:49:32.268457Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T07:49:32.268457Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Yv1ODs/jJCepbmtZ2jc06RzNA67HplgZCpe7j9cGXyIT2+gr6JjX1Jw4xiPxvYe1TXuKsNgBFSAdOoqArbL4Bw==","signature_status":"signed_v1","signed_at":"2026-07-05T07:49:32.268897Z","signed_message":"canonical_sha256_bytes"},"source_id":"2307.00058","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:16f93936cea493c9bc3658e55148082a9d6bec4c097f4f2ada0ae4f920645613","sha256:ffef6131b542c93752b6bcae8284abed49923e7cc548be1c993899afb5badd34"],"state_sha256":"2fca4231761a2e2f27a376f97620e9476920a2ad4a5582f0948f2a9c692ea822"}
