The HI gas of KK153 shows a typical disk-galaxy structure. Using the Baryonic Tully-Fisher relation, we obtained that the distance to KK153 is 2.0_{-0.8}^{+1.7} Mpc. Adopting such distance, we derived a stellar mass of 4.1_{-2.6}^{+10.0}*10^{5} Msun and a neutral gas fraction of 0.63, implying that KK153 is a gas-rich ultra-faint dwarf (UFD) galaxy in the","authors_text":"Chuan-Peng Zhang, Jin-Long Xu, Mei Ai, Ming Zhu, Nai-Ping Yu, Peng Jiang, Xiao-Lan Liu","cross_cats":["astro-ph.CO"],"headline":"","license":"http://creativecommons.org/licenses/by-nc-sa/4.0/","primary_cat":"astro-ph.GA","submitted_at":"2025-03-12T02:22:06Z","title":"FAST Discovery of A Gas-rich and Ultra-faint Dwarf Galaxy: KK153"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2503.08999","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":"sha256:5ed3806da762ee96dd20f4dadd6630a03567b178c637faf2df8980fd16a23914","target":"record","created_at":"2026-07-05T10:29:45Z","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":"a0bd7aa61dd36a215fa471f695c65a049911b5d81acb805acede86bcbbb5b0a6","cross_cats_sorted":["astro-ph.CO"],"license":"http://creativecommons.org/licenses/by-nc-sa/4.0/","primary_cat":"astro-ph.GA","submitted_at":"2025-03-12T02:22:06Z","title_canon_sha256":"89c5661a0f51a97dc664d4aa38b66a2c9996f065a1ac7075105e63592ac5af0b"},"schema_version":"1.0","source":{"id":"2503.08999","kind":"arxiv","version":1}},"canonical_sha256":"28882826f3c22928843d51bc930d4a6caae5cabe0ccef1afb8979c47b875b155","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"28882826f3c22928843d51bc930d4a6caae5cabe0ccef1afb8979c47b875b155","first_computed_at":"2026-07-05T10:29:45.665177Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:29:45.665177Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"uhwLDDViKXGSw2Hvy2kYi7bFXyNL4OKRzE+YKHhZl4qaCZRQi4Ztk6EIXqpAKToMKb04eJ2aSsROfjBZsotAAA==","signature_status":"signed_v1","signed_at":"2026-07-05T10:29:45.665738Z","signed_message":"canonical_sha256_bytes"},"source_id":"2503.08999","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:5ed3806da762ee96dd20f4dadd6630a03567b178c637faf2df8980fd16a23914","sha256:8d1048f30d332bf2871f0bf752748e95a2a83a3e7952dfc77d559bba8dcfb2bd"],"state_sha256":"bd0baf6ab0dd6c06140c188bff40e267da5a71b2a3c994e7f82a5ccca44d402b"}
