By developing a dedicated Einstein-Boltzmann code, we study self-consistently the dynamics of homogeneous cosmology and of linear perturbations without using any parametrization. By evolving linear perturbations with initial conditions in the radiation era, we accurately recover the quasi-static analytic approximation in the matter dominated era. We use Planck 2013 data and a compilation of baryonic acoustic oscillation (BAO) data to constrain the coupling $\\gamma$ to the Ricci cu","authors_text":"Caterina Umilt\\`a, Daniela Paoletti, Fabio Finelli, Mario Ballardini","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2015-07-02T19:52:58Z","title":"CMB and BAO constraints for an induced gravity dark energy model with a quartic potential"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1507.00718","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":"sha256:8c931b595913e800fc5de592cb6fe3fb7cf61b4522158f45d032e1b657e9663a","target":"record","created_at":"2026-05-18T01:35:22Z","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":"23dd4178eb063043133ad4c0c20f439aef9869e59ec6ff021c8504d4c8d55ed0","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2015-07-02T19:52:58Z","title_canon_sha256":"e4dd821a45c3d5104c5c82f39c5451faa3789b5b6a1848212467a59adf9685b2"},"schema_version":"1.0","source":{"id":"1507.00718","kind":"arxiv","version":1}},"canonical_sha256":"5b5a531513916ca0ea90cc0498fc4b80daa8e2a3ac21d28d5b7fd7c222f09f2d","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5b5a531513916ca0ea90cc0498fc4b80daa8e2a3ac21d28d5b7fd7c222f09f2d","first_computed_at":"2026-05-18T01:35:22.067310Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:35:22.067310Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"VdSkBVajjLCEOrvBg67eE4j6d9NJhJhtYczPzAItSmaEPwt/QnTKaEKC9T6yYQ3EJ31SiZtz1UUFZ/Slnwx8Aw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:35:22.068020Z","signed_message":"canonical_sha256_bytes"},"source_id":"1507.00718","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:8c931b595913e800fc5de592cb6fe3fb7cf61b4522158f45d032e1b657e9663a","sha256:85344c025a67bc351382894b6daa57096c766fd796b420473692eefb6a8bd0bc"],"state_sha256":"0e988a362e3b2c06368167de7e926fa3792d3dabd8d446f078633575706fcd69"}
