The observed lines have three distinct features; (1) the line profiles are skewed and show significant low-energy tails, (2) the Fe-K band have low variability, which produces a broad and deep dip in the root-mean-square (rms) spectra, and (3) photons in this band have time lags behind those in the adjacent energy bands with amplitudes of several $R_g/c$, where $R_g$ is the gravitational radius. The \"relativistic light bending model\" is proposed to explain these observed features, where ","authors_text":"Ken Ebisawa, Kotaro Moriyama, Masahiro Tsujimoto, Misaki Mizumoto, Norita Kawanaka, Shin Mineshige","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2018-02-21T13:14:00Z","title":"Can the relativistic light bending model explain X-ray spectral variations of Seyfert galaxies?"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1802.07554","kind":"arxiv","version":2},"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":"sha256:001e73b5b89daa94e2593e1e7fee59759af14989941636f75633f32d17f1d945","target":"record","created_at":"2026-05-18T00:18:11Z","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":"a0dfcf75ec217caa69f263c551f5556a537e8cd8ac2c87d043e9dc29f3e062fe","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2018-02-21T13:14:00Z","title_canon_sha256":"b7d5be042e27769efd7ac3d7b7e7afbc401023776b62356ea7cb2f34993c33b3"},"schema_version":"1.0","source":{"id":"1802.07554","kind":"arxiv","version":2}},"canonical_sha256":"61e9e61d8aab6a2061646d02caafa20074ad04c4b88d496c2f4c87419827f33f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"61e9e61d8aab6a2061646d02caafa20074ad04c4b88d496c2f4c87419827f33f","first_computed_at":"2026-05-18T00:18:11.004236Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:18:11.004236Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"3vbrDvQaQ7JNoRZNtyMK8yaRk/Qa3em6JPjabPR4kGWrpaPa8I/yzetN8XdZvpVu+axeRaI9S3tspEYjgSRGCg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:18:11.004826Z","signed_message":"canonical_sha256_bytes"},"source_id":"1802.07554","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:001e73b5b89daa94e2593e1e7fee59759af14989941636f75633f32d17f1d945","sha256:87716eef5a42ff03d549435e74fc0df1e06089009e4237de13e3a0e3e558b02f"],"state_sha256":"4c7f1d28f6902cccace7ab98ad4f1e7cd3de621dd8e1fbfe19c6455a6836ac2d"}
