Our results indicate that FIR/sub-mm sources at $z \\gtrsim 7$ will experience a strong negative K-correction. Systems of a given virial mass would exhibit larger dust luminosities at higher $z$, as a consequence of the increase in dust temperature driven by the higher temperature floor set by the cosmic microwave background. In addition, high-$z$ systems are more concentrated, which enhances the heating eff","authors_text":"Maria Emilia De Rossi, Volker Bromm","cross_cats":["astro-ph.CO"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.GA","submitted_at":"2019-03-06T17:37:54Z","title":"Redshift Horizon for Detecting the First Galaxies in Far-Infared Surveys"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1903.02512","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:a47627250eee5ccffeea59eb46546c2d292062a6624f1ce01157dc82a7927989","target":"record","created_at":"2026-07-05T00:08:28Z","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":"6bf38e1bbb57b99d7057bb1a72d9ea8c912fbaec26fc52abaaf0f677309632c3","cross_cats_sorted":["astro-ph.CO"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.GA","submitted_at":"2019-03-06T17:37:54Z","title_canon_sha256":"9ee683c7a5e9c6a63f3c02b9a016211aac367220dea6a8b7a0e0fb0a5e74e232"},"schema_version":"1.0","source":{"id":"1903.02512","kind":"arxiv","version":2}},"canonical_sha256":"d5445f56105dd761714c9f837f4bb37bb2dde66c51bdae2cdc127c757858188b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d5445f56105dd761714c9f837f4bb37bb2dde66c51bdae2cdc127c757858188b","first_computed_at":"2026-07-05T00:08:28.480731Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T00:08:28.480731Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"e1gewQj3lGlGGdnMUTniDWaVgyEg6Ab7IDchcv5WExYymI9eIjl4gyd9qp1z8MRVtbD1S2a1EKwFL5TmUWOLBw==","signature_status":"signed_v1","signed_at":"2026-07-05T00:08:28.481168Z","signed_message":"canonical_sha256_bytes"},"source_id":"1903.02512","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a47627250eee5ccffeea59eb46546c2d292062a6624f1ce01157dc82a7927989","sha256:a35b3050495684d9085aa9c19176138161644794e7b4952db9974df2985b1b52"],"state_sha256":"bece8568e00c7a2de6b9cfa4a7e02a6bfc2a5ba1d129bedbabd5f6eafe73d8b6"}
