With a forty-year long history, black hole physics is a fully-blossomed field which promises to embrace several branches of theoretical physics. Here I review the main developments in highly dynamical black holes with an emphasis on high energy black hole collisions and probes of particle physics via superradiance. This write-up, rather than being a collection of well known results, is intended to highlight open issues and the most intriguing results.","authors_text":"Vitor Cardoso","cross_cats":["astro-ph.HE","hep-ph","hep-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2013-06-28T22:03:58Z","title":"Black hole bombs and explosions: from astrophysics to particle physics"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1307.0038","kind":"arxiv","version":4},"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":"sha256:6030df03be2d0c0359ad0fff547e90263ab9877977e84261885ea84e37e8c02d","target":"record","created_at":"2026-05-18T01:49:06Z","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":"5528c4277100dd45842dc9801b49344114c316e797c24f5ea318fdc4e7c8ec61","cross_cats_sorted":["astro-ph.HE","hep-ph","hep-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2013-06-28T22:03:58Z","title_canon_sha256":"1f79a7486b1721460b06df1d6eea44fcd7c566f48dfc9e550017c73286acaec5"},"schema_version":"1.0","source":{"id":"1307.0038","kind":"arxiv","version":4}},"canonical_sha256":"fa3dd75a2729842ef7a0661187cf98e41ffab62d17644b7acca78e36f9dc171e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"fa3dd75a2729842ef7a0661187cf98e41ffab62d17644b7acca78e36f9dc171e","first_computed_at":"2026-05-18T01:49:06.350655Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T01:49:06.350655Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"/d6UtmBusCwBpSA4cLhHyXGic5wpWQrp+STfmPTsil8ujnaODh+ne3FezEnXIZmfIg//cm7EJhHu7HRkMlASAw==","signature_status":"signed_v1","signed_at":"2026-05-18T01:49:06.351061Z","signed_message":"canonical_sha256_bytes"},"source_id":"1307.0038","source_kind":"arxiv","source_version":4}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6030df03be2d0c0359ad0fff547e90263ab9877977e84261885ea84e37e8c02d","sha256:6316d76578ff7b55b5a657a7216a63558f620bc89401b5c56753a370b86cf2b2"],"state_sha256":"6c2c204d82757460bc16bcc3100ec0a86c92779d572c63ba2306b6e8d02237c2"}
