The ASTE wide-band correlator provided simultaneous observations of HCN(4-3) and HCO+(4-3) lines, and a precise determination of their flux ratios. Both galaxies showed high HCN(4-3) to HCO+(4-3) flux ratios of >2, possibly due to AGN-related phenomena. The J = 4-3 to J = 1-0 transition flux ratios for HCN (HCO+) are similar to those expected for fully thermalized (sub-thermally excited) gas in both s","authors_text":"(2) ASIAA, (3) Univ. of Tokyo), Kotaro Kohno (3) ((1) NAO Japan, Kouichiro Nakanishi (1), Masako Yamada (2), Masatoshi Imanishi (1), Yoichi Tamura (1)","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2010-01-04T21:19:32Z","title":"ASTE Simultaneous HCN(4-3) and HCO+(4-3) Observations of the Two Luminous Infrared Galaxies NGC 4418 and Arp 220"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1001.0582","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":"sha256:7523d38d7beb8553f1af38ddd0fcb29b6f1c57432d706024dee48cfe2266ecfa","target":"record","created_at":"2026-05-18T02:10:05Z","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":"dcddf3e231bae45f9dcfff12e18c7cca5c68ceb5eec7e6d3d77185b6fa53fec9","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2010-01-04T21:19:32Z","title_canon_sha256":"62800468927d21f00de22db29c40bd12c288c2b20511839c4fbd561b23a3e1ee"},"schema_version":"1.0","source":{"id":"1001.0582","kind":"arxiv","version":1}},"canonical_sha256":"94636606070c786738d094daf675412b5457fb43d26b225eeb7651d790aee4ec","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"94636606070c786738d094daf675412b5457fb43d26b225eeb7651d790aee4ec","first_computed_at":"2026-05-18T02:10:05.202895Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:10:05.202895Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"P2vJVxhd1i0V0VaFB9T/PvSnotZm8ya7GzRR8OCmHT3E1CVc1ZsDza+gDpiRdAhUqlIRnLT27hsW8najzr+2Cw==","signature_status":"signed_v1","signed_at":"2026-05-18T02:10:05.203460Z","signed_message":"canonical_sha256_bytes"},"source_id":"1001.0582","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7523d38d7beb8553f1af38ddd0fcb29b6f1c57432d706024dee48cfe2266ecfa","sha256:c44e4e176a9b6c12183b9e9141686f71f92495c80ae33fc7b1e3c42c7fd0d629"],"state_sha256":"c0f24f0a56c26399378567bdb7740eecb67de607c697abb7d2b5e6a2fcda8113"}
