We calculate the transfer of photons emitted from the shocked matter with a Monte Carlo code fully taking into account special relativity. As a hydrodynamical model, we use a self-similar solution of Nakayama & Shigeyama (2005). Our calculations reveal that the spectral shape exhibits a double peak or a single peak depending on the shock temperature at the shock breakout. If it is significantly smaller than the rest energy of an electron, the spectrum has a doub","authors_text":"Akihiro Suzuki, Toshikazu Shigeyama, Yukari Ohtani","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2013-09-05T06:21:58Z","title":"Generation of High-Energy Photons at Ultra-Relativistic Shock Breakout in Supernovae"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1309.1239","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:c37a43f3b54c258acc64672a2cea4937e26b594bad63bfd2d01d9aa847b9ed6a","target":"record","created_at":"2026-05-18T01:47:49Z","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":"3be6d37afd406c1f6a2092fbcfb352d36c1c07927eb57abe066f84b87772d178","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2013-09-05T06:21:58Z","title_canon_sha256":"0e9076b84586fb0809e66f939dfb7787b59c842c5a218898f02e7f185fbf3cd9"},"schema_version":"1.0","source":{"id":"1309.1239","kind":"arxiv","version":1}},"canonical_sha256":"ebf996c800f7b5b04ae6112ccbec9bd301899202f91e4ec94a889d826bf235ab","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ebf996c800f7b5b04ae6112ccbec9bd301899202f91e4ec94a889d826bf235ab","first_computed_at":"2026-05-18T01:47:49.578203Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:47:49.578203Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"YKsdHwBnI9zkcrmU0jUHH3x6hXDMvcu0PiCZFMb4xdzLwbklR3gLR2N5XINsOIejAY1j2Nijw1JlebQcVoTdCg==","signature_status":"signed_v1","signed_at":"2026-05-18T01:47:49.578691Z","signed_message":"canonical_sha256_bytes"},"source_id":"1309.1239","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c37a43f3b54c258acc64672a2cea4937e26b594bad63bfd2d01d9aa847b9ed6a","sha256:a559c0fac351325e06b8a3e1bc6e7323557a9d3a615661dc6c6e408665b999f6"],"state_sha256":"7deecef85e052fe4618a6e63517eadde392ce559de57f843a1017af4087b1a63"}
