In this paper, we introduce the novel idea of using this extensive database to test the differential volume expansion rate predicted by two specific models, the concordance $\\Lambda$CDM and $R_{\\rm h}=ct$ cosmologies. For this purpose, we use two well-studied formulations of the GLF, one based on pure luminosity evolution (PLE) and ","authors_text":"Fulvio Melia, Houdun Zeng, Li Zhang","cross_cats":["astro-ph.HE","gr-qc","hep-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2016-07-21T12:37:10Z","title":"Cosmological Tests with the FSRQ Gamma-ray Luminosity Function"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1607.06296","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":"sha256:8dea6e9c7c600dca5ea119c6a8258c03e66024655d6e5ccb5593a476e432e1df","target":"record","created_at":"2026-05-18T01:07:15Z","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":"a63210291d57f9edd6a006433bebd70dc5960d66c3f7c98ab01c97874ce04441","cross_cats_sorted":["astro-ph.HE","gr-qc","hep-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2016-07-21T12:37:10Z","title_canon_sha256":"7534c59847a673efd5e49413282fb273487a235acba3d015e27cbdd3ddffaa57"},"schema_version":"1.0","source":{"id":"1607.06296","kind":"arxiv","version":1}},"canonical_sha256":"70782588dad3bf630f8d5e22f7bff90d461f3b3b0a46f4d16ac440a003c566d7","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"70782588dad3bf630f8d5e22f7bff90d461f3b3b0a46f4d16ac440a003c566d7","first_computed_at":"2026-05-18T01:07:15.675909Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:07:15.675909Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"WsUSTlTfp7q/CqsSEbX4+1xKB7Yd8kRUtmP4fwCrxEHH538BYE55z7CPyTx7Plbol0s76MbPLXIj0Hg51NW8Dw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:07:15.676506Z","signed_message":"canonical_sha256_bytes"},"source_id":"1607.06296","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:8dea6e9c7c600dca5ea119c6a8258c03e66024655d6e5ccb5593a476e432e1df","sha256:aac4145b739e69e5e83fb35cf21cbc4de4f4188104402a9d60a3b60bd85d52e8"],"state_sha256":"6aecb6f95da8d93cde6ad77504d3473ecc07b80589ebc6b86c46a42b36715d4b"}
