We upgraded the prototype TOBA and achieved the strain sensitivity $10^{-10}$ Hz$^{-1/2}$ at around 1 Hz. We operated the upgraded TOBA (called the \"Phase-II TOBA\") located at Tokyo in Japan for 22.5 hours and performed an all-sky coherent search for continuous GWs using the $\\mathcal{F}$-statistic. We place upper limits on continuous GWs from electromagnetically unknown sources in the frequency range from 6 Hz to 7 Hz with the first derivative of","authors_text":"Ayaka Shoda, Kazunari Eda, Masaki Ando, Yousuke Itoh, Yuya Kuwahara","cross_cats":["astro-ph.IM"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2015-11-26T11:00:15Z","title":"All-sky coherent search for continuous gravitational waves in 6-7 Hz band with a torsion-bar antenna"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1511.08354","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":"sha256:8b4e96f9f3c7750bac8d87c94e39fe55d753b8e9ffd6c14e4248fcbb19b7bac2","target":"record","created_at":"2026-05-18T01:21:36Z","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":"95fb123dd2d3f2cd83d4f92483aaa5ba4cf51d8095f59a744106bbb9f358c069","cross_cats_sorted":["astro-ph.IM"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2015-11-26T11:00:15Z","title_canon_sha256":"8e83b8b817edb89822bc7753118f57ee7565c62cb1342ca4305fb1a10bacb337"},"schema_version":"1.0","source":{"id":"1511.08354","kind":"arxiv","version":2}},"canonical_sha256":"6365cf0bb7ac47cc793feb8b53c373b84f68945cde88a20e37d47530aed04b79","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"6365cf0bb7ac47cc793feb8b53c373b84f68945cde88a20e37d47530aed04b79","first_computed_at":"2026-05-18T01:21:36.747575Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:21:36.747575Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Siv2oHqgj2t0d+CQDL7fwBWH+ebvre+FdfMtpGR7n8yzJqmf+2M/80DXb5kF8fqcPdn9H7ZMCmxb8zTpgMqMDg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:21:36.748334Z","signed_message":"canonical_sha256_bytes"},"source_id":"1511.08354","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:8b4e96f9f3c7750bac8d87c94e39fe55d753b8e9ffd6c14e4248fcbb19b7bac2","sha256:27a1f85c79d4ad1538a68d01bf23dd58cdd91436b3b06cc58ba5c01aacee0537"],"state_sha256":"88a3d81815f372499e0ec731354b4d1d062916bd28243da4ad19992a796e5a51"}
