These observations resulted in 93 and 92 detections in the 84- and 36-GHz transitions. While the majority of the 36-GHz sources have been previously reported, many of the sites are observed in the 84-GHz transition for the first time. The near-simultaneous observations of the two transitions revealed strikingly similar spectral profiles and a mean and median 36- to 84-GHz integrated flux density ratio of 2.6 and 1.4.\n  Alongside the 36- and","authors_text":"Joanne Dawson, Maxim Voronkov, Shari Breen, Simon Ellingsen, Tiege McCarthy, Yanett Contreras","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.GA","submitted_at":"2018-12-19T23:23:56Z","title":"84-GHz methanol masers, their relationship to 36-GHz methanol masers and their molecular environments"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1812.08290","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:a01a6d246e8e79d8f254882dd421d2be99cf747be28ae17bd40bd1f114209e77","target":"record","created_at":"2026-05-17T23:55:10Z","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":"85c2141fa7e680783d5d88c0a8ce8ae96685fac49122ed01aa460042b2f98468","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.GA","submitted_at":"2018-12-19T23:23:56Z","title_canon_sha256":"b6805d20d4f0caf0d2c02db59507db80a0916a83998eb1f19fad9bf30c5afbf4"},"schema_version":"1.0","source":{"id":"1812.08290","kind":"arxiv","version":1}},"canonical_sha256":"9b137c08c67e8ca96743d6558de8ae1c48fae8659876896eb1c3a88b90286ee2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9b137c08c67e8ca96743d6558de8ae1c48fae8659876896eb1c3a88b90286ee2","first_computed_at":"2026-05-17T23:55:10.454710Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:55:10.454710Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"OpW+2/hjwfof9pRoKNLOYvVlrTgD3mfeIIWShi/7vbqa1i3XhMDaPkbTrRohb6ZYSHHfYeriEv1jp3nH+71qCw==","signature_status":"signed_v1","signed_at":"2026-05-17T23:55:10.455214Z","signed_message":"canonical_sha256_bytes"},"source_id":"1812.08290","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a01a6d246e8e79d8f254882dd421d2be99cf747be28ae17bd40bd1f114209e77","sha256:59eb4532c895e38b51e87f41b7779678987c68aed6dfffd6a5e61ba6b2570e27"],"state_sha256":"6cb6d0a08c58dd57d5a0d0e5c7784d0ff179e047b8d82b42be9cb479fa9ec8f3"}
