Our fiducial model has previously been shown to fit the properties of local ULIRGs, as well as the number counts of faint sub-mm galaxies. Here, we test the model in detail by comparing the SEDs and stellar, dynamical, gas and halo masses of sub-mm galaxies against observational data. We precisely mimic the sub-mm and radio selection function of the observations and show that the predicted far-infrared properties ","authors_text":"(2) Caltech, (3) Cambridge, (4) IfA, 5), (6) Maryland), Andrew Blain (2), Carlos Frenk (1), Carlton Baugh (1), Cedric Lacey (1), Durham, Edinburgh; (5) UK-ATC, Ian Smail (1), Juan Gonzalez (1) ((1) ICC, Kristen Coppin (1), Laura Hainline (6), Mark Swinbank (1), Rob Ivison (4, Scott Chapman (3)","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph","submitted_at":"2008-09-05T07:42:18Z","title":"The Properties of Sub-mm Galaxies in Hierarchical Models"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0809.0973","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":"sha256:315965e47cbcabbb769b76995e42f19c5c63196f22808483afbbe1cf834b6a33","target":"record","created_at":"2026-05-18T02:15:35Z","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":"51b9535fe0ec9f47ca7ef78b18ca473b1d983dea250434fa7f27c6344e6cab11","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph","submitted_at":"2008-09-05T07:42:18Z","title_canon_sha256":"99147ff1eeda9fa7c140dfe90f0137a21915f340c129c8e31e203dd3db76ccb2"},"schema_version":"1.0","source":{"id":"0809.0973","kind":"arxiv","version":2}},"canonical_sha256":"b4c1eb94643dba186093151d8708cdb892499261b22f7fa74b87722ab8487e9e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b4c1eb94643dba186093151d8708cdb892499261b22f7fa74b87722ab8487e9e","first_computed_at":"2026-05-18T02:15:35.454657Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:15:35.454657Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"OizT9OTCjQlGkg6EVP4JiHW/FtzGkP7+jfA2xOsCH3EBwj5GNZoAymJBUpeb4qJsaeKHy0cK/B2+vMiOFdJlCg==","signature_status":"signed_v1","signed_at":"2026-05-18T02:15:35.455399Z","signed_message":"canonical_sha256_bytes"},"source_id":"0809.0973","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:315965e47cbcabbb769b76995e42f19c5c63196f22808483afbbe1cf834b6a33","sha256:18751dbbd1c259ce446c4ab4c8f6f0290e45d1f1feb99616fd95d61044d8df31"],"state_sha256":"00c0fffab3d813af66c96aee39cdcd5f82669c7200f75127d88124a84d55398b"}
