The burst, also observed by SWIFT/BAT, had a spectrum well fit by the sum of two blackbodies with temperatures of ~4 keV and 10 keV and a fluence in the 0.3-150 keV energy range of ~1e-5 erg/cm2. The X-ray tail had a fluence of ~4e-8 erg/cm2. Thanks to the knowledge of the distances and relative optical depths of three dust clouds between us and 1E 1547.0-5408, we show that most of the X-rays in the tail can be explained by dust ","authors_text":"Andrea Tiengo, Elisa Costantini, Fabio Pintore, Giacomo Vianello, Paolo Esposito, Sandro Mereghetti","cross_cats":["astro-ph.GA"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2017-02-07T18:24:55Z","title":"The effect of X-ray dust-scattering on a bright burst from the magnetar 1E 1547.0-5408"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1702.02127","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":"sha256:57171bd6e2642883e0a1568dd9f236cd69851208f398a0f5f3f6f181eaf72444","target":"record","created_at":"2026-05-18T00:48:14Z","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":"cbc4f22e229e71bae783644ff05a1cf0609c6eb35db6ef8fffae5b82b51d4c35","cross_cats_sorted":["astro-ph.GA"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2017-02-07T18:24:55Z","title_canon_sha256":"c043282633451dc4a6f471ac770b0e4369d7f1ecce3b040022006186bb59e270"},"schema_version":"1.0","source":{"id":"1702.02127","kind":"arxiv","version":1}},"canonical_sha256":"6e110813fe36bd9bd799fc6b263c03d2ff356d97bd23f96b0c4399f71192e9ed","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"6e110813fe36bd9bd799fc6b263c03d2ff356d97bd23f96b0c4399f71192e9ed","first_computed_at":"2026-05-18T00:48:14.777730Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:48:14.777730Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"COE1DPadoLzvIo2x39jSShBzjilyh3zgeVtu0fDC/1cCuLIp1U4GkRwEd6hl+G5B2elUDkJPhNgM8otRvvmtAA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:48:14.778531Z","signed_message":"canonical_sha256_bytes"},"source_id":"1702.02127","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:57171bd6e2642883e0a1568dd9f236cd69851208f398a0f5f3f6f181eaf72444","sha256:488ca287609ceb1514928bd396ef8b34c7f37cc0d432d07661f18912dbf53484"],"state_sha256":"4da20569166bd06afddb7f2dedb62a8adc238ace15e1c85486f9b574879ddfab"}
