In this work, we present a model independent method to investigate the variation of cosmic opacity with redshift. Using strong gravitational lensing data we construct the opacity independent comoving distance function and we use latest supernovae type Ia (SNe Ia) Pantheon+ data to estimate the opacity dependent comoving distances. Using the distance duality equation, opacity parameter is constrained.\n  Our analysis indicates a transparent Universe on ","authors_text":"Meetu Luthra, Savita Gahlaut","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"astro-ph.CO","submitted_at":"2026-05-28T11:51:24Z","title":"Model Independent Probe of Variation of Cosmic Opacity with Redshift"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2605.29805","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":"sha256:6ab08e686434330fb387f3d6b5c9e914f6843758accb3fd137dcc877ef12af98","target":"record","created_at":"2026-05-29T02:05:53Z","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":"371e66a04e0b64cac8729c33334033dfa87333ad39dcf4b53f3bd818d365d15e","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"astro-ph.CO","submitted_at":"2026-05-28T11:51:24Z","title_canon_sha256":"e34d7d07457117a603660b0cfa14079482621ad82484256829603644378f002e"},"schema_version":"1.0","source":{"id":"2605.29805","kind":"arxiv","version":1}},"canonical_sha256":"36d1aeec02b52b033331e3ba1eacc361280afcc79bbda95b05f59846dc0e8504","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"36d1aeec02b52b033331e3ba1eacc361280afcc79bbda95b05f59846dc0e8504","first_computed_at":"2026-05-29T02:05:53.555273Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-29T02:05:53.555273Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"BVYfLdKmCFYyedESotik6cSUmG3UWsLZFshFn+t0raaiMYrtsRtHhcEiujYFr1ONfmwKRuMI83qKofVnH1NHAQ==","signature_status":"signed_v1","signed_at":"2026-05-29T02:05:53.556036Z","signed_message":"canonical_sha256_bytes"},"source_id":"2605.29805","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6ab08e686434330fb387f3d6b5c9e914f6843758accb3fd137dcc877ef12af98","sha256:a13fce5f3bfa240065019e980a8c2d4e695975f3b227ee5e2f6866867b423ead"],"state_sha256":"64cc18282816de91890f6051384210b9f3b3805f9c615efd1d818d43d4ce1d92"}
