In this paper, the momentum space resolution dependence of Boltzmann neutrino transport is studied by performing a series of two-dimensional core-collapse supernova (CCSN) simulations. The effects on the explosion dynamics are discussed by individually varying the resolutions of the zenith and azimuth angles in momentum space, and of the energy. It is found that a coarse zenith angle resolution artificially facilitates the explosion, even turning non-explodi","authors_text":"Ryuichiro Akaho","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2026-07-14T15:33:32Z","title":"Momentum Space Resolution Dependence in Boltzmann Neutrino Radiation Hydrodynamics Simulations of Core-collapse Supernovae"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2607.12891","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:ff76e1281996d6ceb014ede1c97ccd2ebe10ed66e79a4e7d583020610fbb61ae","target":"record","created_at":"2026-07-15T01:22:23Z","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":"b18f5ea023d4e642ff4bdb7435718f19ec97940cbca9041f1f788e5e20d6ef40","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2026-07-14T15:33:32Z","title_canon_sha256":"0c2788e6ca317cf20aa2f0593cc52eec063d2d960029803aa54b28712ba9ab9d"},"schema_version":"1.0","source":{"id":"2607.12891","kind":"arxiv","version":1}},"canonical_sha256":"70b6795846d7defaff7234904c2745e5f459e37120d44d16c7da1615c29c1f2a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"70b6795846d7defaff7234904c2745e5f459e37120d44d16c7da1615c29c1f2a","first_computed_at":"2026-07-15T01:22:23.496420Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-15T01:22:23.496420Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"a/h1JVnswgib0/uaHHG/stEDyqMvm4cl5I+P4TnZKfzbNarU0ISw2DYxqUaoG7tAixMfRXDk9XXrcZFY4lASAg==","signature_status":"signed_v1","signed_at":"2026-07-15T01:22:23.497229Z","signed_message":"canonical_sha256_bytes"},"source_id":"2607.12891","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:ff76e1281996d6ceb014ede1c97ccd2ebe10ed66e79a4e7d583020610fbb61ae","sha256:fa35e638ccc075c9d6effa4ecd17d37b90828604f4ab28a165ab5b4118d27fb5"],"state_sha256":"5a45cdae0239e67a9fd2a0b81f3003c0cf7e2b715fd73906c538ce9eba5fdebc"}
