The impact of second order effects accounting for the non-linear evolution of large-scale structures is evaluated propagating for the first time the full CMB lensing jacobian together with the light rays trajectory. We carefully investigate the robustness of our approach against several numerical effects in the raytracing procedure and in the N-","authors_text":"Carmelita Carbone, Giulio Fabbian, Matteo Calabrese","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2017-02-10T20:20:18Z","title":"CMB weak-lensing beyond the Born approximation: a numerical approach"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1702.03317","kind":"arxiv","version":3},"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:c1077b4a2156c9f0f1ad03ab63415a7ac9457a1f1d30d37142c9a670f663b957","target":"record","created_at":"2026-05-18T00:22:06Z","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":"581a22bdea8a234c608eb84a1fb620f1995066ac065e862ad54cdce4c9cd3ea1","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2017-02-10T20:20:18Z","title_canon_sha256":"bc96b532d2f751b1975dfb708e7bb746f53d3c35a3e7bdf34296d4fb7d7156af"},"schema_version":"1.0","source":{"id":"1702.03317","kind":"arxiv","version":3}},"canonical_sha256":"2af4d464cb22fde89aa990fd90593b7f8dcebc155be386c132e8e3ee6e57d475","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2af4d464cb22fde89aa990fd90593b7f8dcebc155be386c132e8e3ee6e57d475","first_computed_at":"2026-05-18T00:22:06.361787Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:22:06.361787Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"HBNKlYGEzLuXBkbD6zyY68KCFYAMwgN97BWFnd3gfUUk69pb+9uuKm6F0DvIvMW1HT6MMjLz0rJOXbdXcTDUBw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:22:06.362288Z","signed_message":"canonical_sha256_bytes"},"source_id":"1702.03317","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c1077b4a2156c9f0f1ad03ab63415a7ac9457a1f1d30d37142c9a670f663b957","sha256:e7d135862e766019b1e4a3ccd6d580f778c97d909cb071761d89a3ada3b80f68"],"state_sha256":"23f0259e5f5a3b40d74f49d2c670c7aab81c2ff1bd6901f1575eb6093549c323"}
