Our models were chosen to lie within similar mass DM halos, log(Mvir/Mo) ~ 11.65 +- 0.05, at z=6, 4, and 2, in high and low overdensity environments. We apply two galactic wind feedback mechanisms for each model. All galaxies develop sub-kpc stellar bars differing in their properties. We find that (1) The high-z bars form in response to various perturbations: mergers, close flybys, cold accretion inflows along the cosmological filaments, etc.; (2) These bars account ","authors_text":"Bonn, Da Bi (University of Kentucky, Emilio Romano-Diaz (Argelander-Institute for Astronomy, Germany), Isaac Shlosman (University of Kentucky, Japan), Osaka University, Theoretical Astrophysics, USA, USA)","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.GA","submitted_at":"2021-12-17T19:00:14Z","title":"Modeling Evolution of Galactic Bars at Cosmic Dawn"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2112.09718","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:f72b48787d58b269bf72e92e51461a3b3efe2ca951cc6e7869f5a8f86598d4d4","target":"record","created_at":"2026-07-05T04:45:14Z","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":"c283e7d04c16c2a03303c3531c989e6ea24104e5a7ab60f504822341d7bdbbfd","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.GA","submitted_at":"2021-12-17T19:00:14Z","title_canon_sha256":"bc8c6b889abb057abb34ebaf30715fdb307c473da23beb4885f69a70857daf47"},"schema_version":"1.0","source":{"id":"2112.09718","kind":"arxiv","version":2}},"canonical_sha256":"232f39632bec3bcba55af351fd629026a0336e5f4947f8b27aef668d174632e7","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"232f39632bec3bcba55af351fd629026a0336e5f4947f8b27aef668d174632e7","first_computed_at":"2026-07-05T04:45:14.610359Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T04:45:14.610359Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"ZOZrCpJD9g+pf3PlBz5+sP6EWc+UXYKZk6+P/vIRrK6FNEPc7MRyoETFAXL0AyZgm+G24NT9mf033HNNI0GcDw==","signature_status":"signed_v1","signed_at":"2026-07-05T04:45:14.610793Z","signed_message":"canonical_sha256_bytes"},"source_id":"2112.09718","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f72b48787d58b269bf72e92e51461a3b3efe2ca951cc6e7869f5a8f86598d4d4","sha256:1149ff32e21262b7fbbdb428360c17ede788994a0f328547493002ccd4c02788"],"state_sha256":"f1452ab2a9e64bec6840a4a55b11666a2d7d7cba19a4ee9a02156dd83352fb05"}
