It clearly shows a filled-center structure in the X-ray region while a shell structure in the radio region. There are two radio bright regions: one is in the center, while the other is in the east rim. The X-ray intensity peak coincides well with the radio bright region at the center. The X-ray spectrum was well-fitted by a collisional ionization equilibrium model with solar abundances. Taking into account the ionization parameter (>10^{12} cm^{-3} s) and the plasma density (0.39 cm^{-3}), we found t","authors_text":"Emi Miyata, Hideyuki Enoguchi, Hiroshi Tsunemi, Kumi Yoshita","cross_cats":[],"headline":"","license":"","primary_cat":"astro-ph","submitted_at":"2002-04-25T12:48:52Z","title":"Observation of Kes 27: A Typical Mixed-Morphology SNR"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"astro-ph/0204427","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":"sha256:45744372e48133f3ce493c456635937c05ca898a4e06a3c72bd39f46888173ce","target":"record","created_at":"2026-05-18T01:40:42Z","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":"50cd30aa1a3989ce8dc0a7e6f06150710dec284ead1a60554afce55fdc493bb3","cross_cats_sorted":[],"license":"","primary_cat":"astro-ph","submitted_at":"2002-04-25T12:48:52Z","title_canon_sha256":"f42988b7b24009284e1aa2a0539dbc0b42630bb05b44c293caafa3c595bdcced"},"schema_version":"1.0","source":{"id":"astro-ph/0204427","kind":"arxiv","version":1}},"canonical_sha256":"e724dd1ebb911a31f11640d903bd3b4cd37c6d4ddc4b494f22ae0c9333536bcd","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"e724dd1ebb911a31f11640d903bd3b4cd37c6d4ddc4b494f22ae0c9333536bcd","first_computed_at":"2026-05-18T01:40:42.903474Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:40:42.903474Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"USUWeaVzc3nGhSQgNJdpylnw6R0NbMUfqaLteoCJtQUAqhlCm5QCmFNRGtXGVnrjYG/oTfO1mkDCUe255yDuDA==","signature_status":"signed_v1","signed_at":"2026-05-18T01:40:42.904260Z","signed_message":"canonical_sha256_bytes"},"source_id":"astro-ph/0204427","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:45744372e48133f3ce493c456635937c05ca898a4e06a3c72bd39f46888173ce","sha256:1b87bac7fb018da023727612f19984afe5ed3e9a6857d29d35023b0c7e30bc7b"],"state_sha256":"e1c02f1dcefb45b470b44143134e936f10e9440abc448529bcb6792dfe556937"}
