In recent years, an increasing number of doubly-lensed events have been observed, where a secondary lens crosses the line of sight. This causes additional or distorted scintillation arcs over time scales ranging from days to months. In this work we report such a transient event for pulsar B1737+13 and propose a possible lensing geometry including the distance to both lenses, and the orientation of the main scree","authors_text":"Daniel Baker, Dan Stinebring, Samuel Siegel, Ue-Li Pen, Yen-Hua Chen","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"astro-ph.GA","submitted_at":"2024-12-13T18:01:51Z","title":"Transient Blurring of the Scintillation Arc of Pulsar B1737+13"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2412.10323","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:edf960a8d417298f4392744794f8e7a3d59c1dde29490ef31fc62e3a553f7abf","target":"record","created_at":"2026-07-05T10:11:30Z","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":"c3bf0a4de66842fda7eac91d64221c9db612d09674b06808f894038974fedf27","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"astro-ph.GA","submitted_at":"2024-12-13T18:01:51Z","title_canon_sha256":"4bb4ba17e74725cb732f5141979bed3eeaab11ebfc4cb39d8c94d47c19ff3d3a"},"schema_version":"1.0","source":{"id":"2412.10323","kind":"arxiv","version":1}},"canonical_sha256":"a0c774da1ad4088542165c43e8586a6a999e995b2cc084fb5be66300c276a8a3","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a0c774da1ad4088542165c43e8586a6a999e995b2cc084fb5be66300c276a8a3","first_computed_at":"2026-07-05T10:11:30.329693Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:11:30.329693Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"6oyUM9zKooSZ+0/jS+Zi6qY+Y9do2O/Wy3u8HyHJ8gRIKcexbLJrTReHrl+k4tUAvVoz0LvvSjwtnTveIa/SCg==","signature_status":"signed_v1","signed_at":"2026-07-05T10:11:30.330226Z","signed_message":"canonical_sha256_bytes"},"source_id":"2412.10323","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:edf960a8d417298f4392744794f8e7a3d59c1dde29490ef31fc62e3a553f7abf","sha256:3972d851557df33278c8a11fcabb77b348086ec41718ea469e85b36afcc90ebc"],"state_sha256":"7f3da13dc27e8f0d5d76f1688feb038cc88019845afe41512c4cc09dfa31b268"}
