Here, we explore the observational implications of such a mixed thermal-nonthermal particle distribution for the afterglow and prompt emission of gamma-ray bursts. When the Maxwellian component dominates the energy budget, the afterglow lightcurves show a very steep decline phase followed by a more shallow decay when the characteristic synchrotron frequency crosses the obs","authors_text":"Anatoly Spitkovsky (Princeton), Dimitrios Giannios","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2009-05-12T21:36:32Z","title":"Signatures of a Maxwellian Component in Shock-Accelerated Electrons in GRBs"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0905.1970","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":"sha256:8ae4c09bbb233650ce52c79176e0b4e34d2aa2807ca5e38e16e4b2ea296b6086","target":"record","created_at":"2026-05-18T02:13:39Z","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":"9e3142b2c8c64a97b18e6cf7a3c16079c49997d81d4a342e9292533a80dd5385","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2009-05-12T21:36:32Z","title_canon_sha256":"8ff6b23ed8c23bbae04fde708256cd778a5d1ce180812c340bc92ce32d8484c7"},"schema_version":"1.0","source":{"id":"0905.1970","kind":"arxiv","version":2}},"canonical_sha256":"d1ab5db9854d28128e4f741ca86dfe01b5ecdf91ffb1a7f3dde6199c24d9c55b","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"d1ab5db9854d28128e4f741ca86dfe01b5ecdf91ffb1a7f3dde6199c24d9c55b","first_computed_at":"2026-05-18T02:13:39.793053Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T02:13:39.793053Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"kohaeDpyaTWeLhehq1C3/+kVIQpbOsM1weVt7F4U8yyCp+BSAloipvgiCNQHGaWlA2jtzpuybYkloQnvNbimBA==","signature_status":"signed_v1","signed_at":"2026-05-18T02:13:39.793497Z","signed_message":"canonical_sha256_bytes"},"source_id":"0905.1970","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:8ae4c09bbb233650ce52c79176e0b4e34d2aa2807ca5e38e16e4b2ea296b6086","sha256:b12dd4b5145ea5bc8f5df032a716259be40cfa9c46828498109988f99b41b7e1"],"state_sha256":"3cda98aae95c5c9dd8bb86113427e8847b9c3ecb0c5240f59da0e77bc302659c"}
