The broad observational facts and empirical phenomenological relations of the GRB prompt emission and afterglow are outlined. A well-tested, successful fireball shock model is introduced in a pedagogical manner. Several important uncertainties in the current understanding of the phenomenon are reviewed, and prospects of how future experiments and extensive observational and theoretical efforts may address these problems are discussed.","authors_text":"Bing Zhang (PSU & CITA), Peter Meszaros (PSU & IAS)","cross_cats":[],"headline":"","license":"","primary_cat":"astro-ph","submitted_at":"2003-11-13T18:33:29Z","title":"Gamma-Ray Bursts: Progress, Problems & Prospects"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"astro-ph/0311321","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":"sha256:873be27e57569728110e771a15644f439c2a8cdb8a596212dc5d07424637a5f3","target":"record","created_at":"2026-07-04T14:13:11Z","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":"0a2a84b7c48ca696bd26521de6435dea8b75cec700e4369263899d0ecce652c2","cross_cats_sorted":[],"license":"","primary_cat":"astro-ph","submitted_at":"2003-11-13T18:33:29Z","title_canon_sha256":"f9e6f0e96327238694517e89df52317071c901c547c3c2ecdead765214a3b55a"},"schema_version":"1.0","source":{"id":"astro-ph/0311321","kind":"arxiv","version":1}},"canonical_sha256":"2b95ffb1580c277ea23e4e78e7a3bfa898521a1878b9b95ad000d2066110c110","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"2b95ffb1580c277ea23e4e78e7a3bfa898521a1878b9b95ad000d2066110c110","first_computed_at":"2026-07-04T14:13:11.528311Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T14:13:11.528311Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"QXzYUCe4u7vkD8ebBoxrFho4865g74Vdk785XYfGmU0YgyE7LQm3dKcCHY5wjS43VIIQ9JJBbEP0h2BgWQExCg==","signature_status":"signed_v1","signed_at":"2026-07-04T14:13:11.528732Z","signed_message":"canonical_sha256_bytes"},"source_id":"astro-ph/0311321","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:873be27e57569728110e771a15644f439c2a8cdb8a596212dc5d07424637a5f3","sha256:2f5d9fe4418e2f8586c8682fae425de8b6ac6d0bb945b05bf391a37ee3800fb4"],"state_sha256":"5fd91c83f456bba7cd580579f69d5fefe66c21c727b33318e3efdcd7dc2055d7"}
