The newly discovered HI cloud appears to be a typical disk galaxy since it has a double-peak shape in the global HI profile and an S-like rotation structure in the velocity-position diagram. Moreover, this disk galaxy has an extremely low absolute magnitude (M_B>-10.0 mag) and stellar mass (<6.9*10^5 Msun). Furthermore, we obtained that the HI mass of this galaxy is 8.3*1","authors_text":"Chuan-Peng Zhang, Jin-Long Xu, Mei Ai, Ming Zhu, Naiping Yu, Peng Jiang, Xiao-Lan Liu","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"astro-ph.CO","submitted_at":"2023-02-06T09:41:55Z","title":"Discovery of an isolated dark dwarf galaxy in the nearby universe"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2302.02646","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":"sha256:67a66714860907e173884a70bf13dedcef59de023f80b0802c232787daf9bb71","target":"record","created_at":"2026-07-05T05:46:37Z","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":"d3c35e7a8ee3fd916ad345ed1b653ab63fd0509c8d221e896035d27257590f02","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"astro-ph.CO","submitted_at":"2023-02-06T09:41:55Z","title_canon_sha256":"a640a1a9fa2cb23a2fec4e98895dbd15e5441429b41225ae0f8d0beb2dcd4f15"},"schema_version":"1.0","source":{"id":"2302.02646","kind":"arxiv","version":1}},"canonical_sha256":"2bd3ec8675a56f8635961fc70f8852fecabe0770c7a8da4a7475035bd4389f90","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2bd3ec8675a56f8635961fc70f8852fecabe0770c7a8da4a7475035bd4389f90","first_computed_at":"2026-07-05T05:46:37.248992Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T05:46:37.248992Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"im4UF5RgHMJR8Q05KK1NyRbVVl1Qz2xBZyhsOz8AkROLVITx4UzwjWe7p7qicvfNTyLXW486blEIW8XQaekcAw==","signature_status":"signed_v1","signed_at":"2026-07-05T05:46:37.249431Z","signed_message":"canonical_sha256_bytes"},"source_id":"2302.02646","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:67a66714860907e173884a70bf13dedcef59de023f80b0802c232787daf9bb71","sha256:9e75e4e5eb51ba8b047d5205ee8c49ec419ecebceff699574909eeb66e3b9cba"],"state_sha256":"15cd30b8a200b860854c2568b3c04ce5c3ade64503e818468b6b0eab6d5b6cef"}
