However, detected LCEs at $z>4$ are quite rare. Here we report an LCE candidate at $z = 4.444$, dubbed LCEz4-M1, which is one of the highest-redshift LCE candidates currently known. The redshift is determined from the Ly$\\alpha$ emission line detected in the VLT/MUSE spectrum. The Lyman continuum (LyC) signal is detected independently in the \\emph{Hubble Space Telescope} (HST) F435W image and the VLT/MUSE spectrum at significances of $\\simeq3.7~\\sig","authors_text":"Chunyan Jiang, Fang-Ting Yuan, Fuyan Bian, Ruqiu Lin, Shuairu Zhu, Xiaer Zhang, Yucheng Guo, Zhen-Ya Zheng","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"astro-ph.GA","submitted_at":"2026-03-02T05:52:02Z","title":"LCEz4-M1: A Lyman Continuum Emitter Candidate at z = 4.444 in the MUSE Hubble Ultra Deep Field"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2603.01487","kind":"arxiv","version":3},"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":"sha256:7874b94ef12ad79e5b2a114756f147af746d8e15567dd2254abb6e9e242b55b1","target":"record","created_at":"2026-06-02T03:04:39Z","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":"4fa0ee928e5edfb281f8704500e322f4a2a214c3c92cf78953993ef55fae81f3","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"astro-ph.GA","submitted_at":"2026-03-02T05:52:02Z","title_canon_sha256":"c9ed22a4d14a6441c4d7f39c9bde9add2c3f6f083993d814c57c3eb226622028"},"schema_version":"1.0","source":{"id":"2603.01487","kind":"arxiv","version":3}},"canonical_sha256":"9c7fa4a4d18675e74bcdec7c5e1d15fb6a0cf1ebe6e42b07a3885b706e988d79","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9c7fa4a4d18675e74bcdec7c5e1d15fb6a0cf1ebe6e42b07a3885b706e988d79","first_computed_at":"2026-06-02T03:04:39.659546Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-02T03:04:39.659546Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"95eF9A051KNLMtfCtL1xa3gIr0qMhs+fAubJb/d4YnvA6bbH5kQlGK7jquonc4g1MIxPAEUViLdV+xw4s1BJDA==","signature_status":"signed_v1","signed_at":"2026-06-02T03:04:39.660054Z","signed_message":"canonical_sha256_bytes"},"source_id":"2603.01487","source_kind":"arxiv","source_version":3}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7874b94ef12ad79e5b2a114756f147af746d8e15567dd2254abb6e9e242b55b1","sha256:569c87fd42e780770fc673da4d9c9349c390579e4b44e61c4d92fb8bf3393db8"],"state_sha256":"92fbc46e0003a5d9605c2c1f4d399673b024f35d834e2dee79627b99bdaa46ea"}
