Afterthe discovery on 2017 September 2 made independently with MAXI and the Swift/BAT, the source brightened gradually, and in a few weeks, reached the peak intensity of ~5 Crab, or ~1.6 x 10^{-7} erg cm^{-2} s^{-1} in terms of the 2--20 keV flux. On the initial outburst rise, the X-ray spectrum was described by a power-law model with a photon index of ~2, while after a hard-to-soft transition which occurred on September 18, the spectrum required a disk blackbod","authors_text":"Hitoshi Negoro, Kazuo Makishima, Kazutaka Yamaoka, Kotaro Morita, Megumi Shidatsu, Nobuyuki Kawai, Satoshi Nakahira, Tatehiro Mihara, Tomofumi Kawase, Yoshihiro Ueda","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2018-04-03T02:58:19Z","title":"Discovery and state transitions of the new Galactic black hole candidate MAXI J1535-571"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1804.00800","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:f57e1c407e89028aaf59992e7a045f060cf1a1f99f4280375cbc658eb8d7ad9d","target":"record","created_at":"2026-05-18T00:05:56Z","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":"ef50e56ec6b959cb5f4a6a0a90e813ec5de7d95a07d8c06a519628686be3690e","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2018-04-03T02:58:19Z","title_canon_sha256":"4600de51bb08a7e9c4108f84699051da22fb277f51b0862e0620e3ad37062cf7"},"schema_version":"1.0","source":{"id":"1804.00800","kind":"arxiv","version":2}},"canonical_sha256":"5c665afbfa1c99025b35c028687b57bee18e7e67f6e7968a599414457ff529e2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"5c665afbfa1c99025b35c028687b57bee18e7e67f6e7968a599414457ff529e2","first_computed_at":"2026-05-18T00:05:56.207559Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:05:56.207559Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"dUecCFfjfuGuPzpLKFL8srSGlirwxIiJIOee10FjT7TNTNh4wOPEYPeZj5NzvysR3jgXROqZvSR7si18Qs4MBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:05:56.208088Z","signed_message":"canonical_sha256_bytes"},"source_id":"1804.00800","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f57e1c407e89028aaf59992e7a045f060cf1a1f99f4280375cbc658eb8d7ad9d","sha256:f5b53ca8c8bbb4bbf8c6d9d04bcdf6cd8836ea2ebebc8b637b70e330ae6719a2"],"state_sha256":"e8c341db14e9c36f415262c7b52ffe606e60ef082c5af110c38e73c90bce8cbe"}
