However, the detailed kinematics and geometry of hidden BLRs are still not fully understood. The virial factor obtained from reverberation mapping of type 1 AGNs may be a useful diagnostic of the nature of hidden BLRs in type 2 objects. In order to understand the hidden BLRs, we compile six type 2 objects from the literature with polarized BELs and dynamical measurements o","authors_text":"Jian-Min Wang, Pu Du, Zhi-Xiang Zhang","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.GA","submitted_at":"2017-04-14T04:39:11Z","title":"Hidden Broad-line Regions in Seyfert 2 Galaxies: from the spectropolarimetric perspective"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1704.04345","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":"sha256:8941f3393ae3187ccbacca8781901e1c9e9438d7cde06913592c35721cbcb247","target":"record","created_at":"2026-05-18T00:45:10Z","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":"9d05b7e687c60344de5cddadb7597685f71e952dd70ee5007b5c27ffc6050170","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.GA","submitted_at":"2017-04-14T04:39:11Z","title_canon_sha256":"406d4a6c4a729038316e8292eec0354acf19af7f031c20ca95594d8934ddfdfa"},"schema_version":"1.0","source":{"id":"1704.04345","kind":"arxiv","version":2}},"canonical_sha256":"911200008b1fcbbd536d1d42af147a4887ec2c6e28330edfd108f591967c4f68","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"911200008b1fcbbd536d1d42af147a4887ec2c6e28330edfd108f591967c4f68","first_computed_at":"2026-05-18T00:45:10.688178Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:45:10.688178Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"jtdvpts2eNa/TqNwaHANPB5j4tDCmGyutLX/PFbL425igGvfWAvgdKNhVh8uX8/IrqO9i680rTLLKeSkwS7YCQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:45:10.688716Z","signed_message":"canonical_sha256_bytes"},"source_id":"1704.04345","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:8941f3393ae3187ccbacca8781901e1c9e9438d7cde06913592c35721cbcb247","sha256:fcd20ab22929ae575493a0d11a731537a7aeaf1a9c00a72bd4eb37d9b8b7406d"],"state_sha256":"515837c7a48e7f3a53e65380bd5b62c6ccec7afaaab08a91f98b56ffddd3abda"}
