They appear when a new black hole, created after the explosion of a massive star or the merger of two compact stars, quickly accretes the matter around it and ejects a transient relativistic jet in our direction. This review discusses the various types of gamma-ray bursts, their progenitors, their beaming and their rate in the local universe. We emphasize the broad astrophysical interest of GRB studies, and the crucial role of high-energy satellites as exclusive suppliers of GRB alerts and initial locations.","authors_text":"Jean-Luc Atteia","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by-nc-sa/3.0/","primary_cat":"astro-ph.HE","submitted_at":"2013-02-26T15:37:52Z","title":"Gamma-Ray Bursts, witnessing the birth of stellar mass black holes"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1302.6461","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:b6131e54f092425a1557382ecb186f086cef2eba267925f36c7365cd3ce28944","target":"record","created_at":"2026-05-18T03:32:29Z","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":"a8cb42ae1e7609fe307888bc1ac3623b84a60ad87c8f71cc5ed206691209fbbe","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by-nc-sa/3.0/","primary_cat":"astro-ph.HE","submitted_at":"2013-02-26T15:37:52Z","title_canon_sha256":"5d19e86c7bace6d4b7b3f24f392e75156790f2c446060c1a692685be67196adc"},"schema_version":"1.0","source":{"id":"1302.6461","kind":"arxiv","version":1}},"canonical_sha256":"1843c03e1a2caa64a886c7d8f9f2ca3dce9b915cdcb58f420ed650481b2733cc","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"1843c03e1a2caa64a886c7d8f9f2ca3dce9b915cdcb58f420ed650481b2733cc","first_computed_at":"2026-05-18T03:32:29.147500Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:32:29.147500Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"wJp7npDmSFLkYiWYO6GXMx9bTDUoPP7En8PUVeGQcGlD1w32lu66oGjghUfVvnnn7pl8HaZQSiZS4UPjIylcCA==","signature_status":"signed_v1","signed_at":"2026-05-18T03:32:29.148283Z","signed_message":"canonical_sha256_bytes"},"source_id":"1302.6461","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b6131e54f092425a1557382ecb186f086cef2eba267925f36c7365cd3ce28944","sha256:dd7da214fb0d633aa5198887065db29b5ab797a166617dfe8c56afc04d776e0a"],"state_sha256":"9b5321d465d5fc70855b96a42e83359bef857394aadc0daff5b392a9e72b7250"}
