Such a balance is secularly stable provided that the star formation rate increases with the pressure in the star forming gas. The $I\\kappa\\epsilon\\alpha$ model has four parameters that together control the feedback from star formation and the cosmological accretion rate onto a halo. $I\\kappa\\epsilon\\alpha$","authors_text":"Mahavir Sharma (Curtin), Tom Theuns (Durham)","cross_cats":["astro-ph.CO","astro-ph.SR","physics.app-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.GA","submitted_at":"2019-06-24T18:00:02Z","title":"The $I\\kappa\\epsilon\\alpha$ model of feedback-regulated galaxy formation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1906.10135","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":"sha256:77c2f8236bb133c71a088c98817e7ba0141e73da17bf74b8871d185a75a16a05","target":"record","created_at":"2026-07-05T00:31:08Z","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":"81e23fab93bfcf3bfea1a58d4071007a31d1f16e0a67e56d7a55987cfb176d65","cross_cats_sorted":["astro-ph.CO","astro-ph.SR","physics.app-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.GA","submitted_at":"2019-06-24T18:00:02Z","title_canon_sha256":"d14dce502cac11e5a7a6def187cd802e5e984c4c40b5198aa3ca3b468aeaeb81"},"schema_version":"1.0","source":{"id":"1906.10135","kind":"arxiv","version":2}},"canonical_sha256":"898d622948740567399fa27d9e110b3b0bfdf365cf3d6bf2dd72a82b3f19bc3c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"898d622948740567399fa27d9e110b3b0bfdf365cf3d6bf2dd72a82b3f19bc3c","first_computed_at":"2026-07-05T00:31:08.794686Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T00:31:08.794686Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"mWkalaBwD8KCVcUniR2rjFZEhKB2crog7E7GWzSk55bT2nNxQ6oeVIi2w9DvETKbHIDojQ348Q15lWgMXptUAw==","signature_status":"signed_v1","signed_at":"2026-07-05T00:31:08.795196Z","signed_message":"canonical_sha256_bytes"},"source_id":"1906.10135","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:77c2f8236bb133c71a088c98817e7ba0141e73da17bf74b8871d185a75a16a05","sha256:5da01fd095fefa208613f3d7d66b910fcfbb6e898148af107d190f432c036391"],"state_sha256":"6647213c37756d046828a2f2d0e26c21aceb1b135799c0bf2d99c702169bc715"}
