For many years long GRBs were the focus of intense research while the lack of observational data limited the study of short-hard GRBs (SHBs). In 2005 a breakthrough occurred following the first detections of SHB afterglows, longer wavelength emission that follows the burst of gamma-rays. Similarly to long GRBs, afterglow detections led to the identification of SHB host galaxies and measurement of their redshifts. These observations established that SHBs are cosmological re","authors_text":"Ehud Nakar","cross_cats":[],"headline":"","license":"","primary_cat":"astro-ph","submitted_at":"2007-01-25T21:11:05Z","title":"Short-Hard Gamma-Ray Bursts"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"astro-ph/0701748","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":"sha256:16c5d204c8c0f5a732014049d1d79d18a7882fb2bda96d3b3875d7ef694fc9d4","target":"record","created_at":"2026-07-04T17:25:18Z","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":"1f9ad984101042d8737218273cbaf143857f476e84999f1374ef27bf1e315c81","cross_cats_sorted":[],"license":"","primary_cat":"astro-ph","submitted_at":"2007-01-25T21:11:05Z","title_canon_sha256":"f8ba2a90155b40c58b77984750859052340097f6b6dfbb6f77394c976e98f1de"},"schema_version":"1.0","source":{"id":"astro-ph/0701748","kind":"arxiv","version":2}},"canonical_sha256":"bb24213c510fd27f98f7972976b7f0ddff80137bf3f7e924948bef19816e56c6","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"bb24213c510fd27f98f7972976b7f0ddff80137bf3f7e924948bef19816e56c6","first_computed_at":"2026-07-04T17:25:18.261955Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T17:25:18.261955Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"XA793w5LdH5tedPMgZkwUDBNuNAuZ4jAZNQ2Kqa7EDSFZnHoncXD34CadgUqXRHiSSMpTvBDEP6/r7BxAOwECw==","signature_status":"signed_v1","signed_at":"2026-07-04T17:25:18.262392Z","signed_message":"canonical_sha256_bytes"},"source_id":"astro-ph/0701748","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:16c5d204c8c0f5a732014049d1d79d18a7882fb2bda96d3b3875d7ef694fc9d4","sha256:421035b9d017591ecc66d752e567ecd0c69b883c273cf24d3c9195d62bc57469"],"state_sha256":"b895acb274f2e85008eccab4382802d36858aa6a8e16a4d3cd756733ca497225"}
