The gravitational coupling evolution induces a modification of the Friedman equation with respect to the $\\Lambda$CDM model, which we study in both the Einstein and Jordan frame. We consider a phenomenological parametrization of the low redshift variation of the coupling in a narrow redshift shell, showing how it can affect the distance of the anchors used to calibrate supernovae (SNe), while higher redshift backgroun","authors_text":"Antonio Enea Romano","cross_cats":["astro-ph.CO","hep-th"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"gr-qc","submitted_at":"2024-02-19T08:42:34Z","title":"The Effects of the Gravitational Coupling Variation on the Local $H_0$ Estimation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2402.11947","kind":"arxiv","version":4},"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":"sha256:2513a1f5f39eb69629b05ac8ca8524bfa9929e1a8a2456d09ce954a52fa28be4","target":"record","created_at":"2026-07-05T12:02:33Z","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":"64b59e0f0d48ba5ca3ebc3043151bd857a6d540ed6afe8873be596636fe9a576","cross_cats_sorted":["astro-ph.CO","hep-th"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"gr-qc","submitted_at":"2024-02-19T08:42:34Z","title_canon_sha256":"dd9f123180cca77dacefc79719ea4e77e06d43fa65cceb905ee5d3c847035b4e"},"schema_version":"1.0","source":{"id":"2402.11947","kind":"arxiv","version":4}},"canonical_sha256":"dfefc94de9e330b1319f1994e6ad69216fb3498a0607717c411566625720c5d3","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"dfefc94de9e330b1319f1994e6ad69216fb3498a0607717c411566625720c5d3","first_computed_at":"2026-07-05T12:02:33.366350Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T12:02:33.366350Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"IyNuAyL0E2b5LSDLCAyxHZRapw9aJTn2U0RAEr9qS3nRYfFgBOPS2cxlIhCuQ0WhuU6Lkfv6O3OuvozKomq9Bg==","signature_status":"signed_v1","signed_at":"2026-07-05T12:02:33.366825Z","signed_message":"canonical_sha256_bytes"},"source_id":"2402.11947","source_kind":"arxiv","source_version":4}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:2513a1f5f39eb69629b05ac8ca8524bfa9929e1a8a2456d09ce954a52fa28be4","sha256:6de985a727b13e99e20338ade87b87eb034149b82e31b20feb4d0c6afe976c77"],"state_sha256":"51052a204c25208e3723b24ab0dd42f73e65c15ab1ca60a9a0f966318ae93658"}
