We focus on head-on collisions of non-spinning black holes, starting from rest and with the same charge to mass ratio, Q/M. The addition of charge to black holes introduces a new interesting channel of radiation and dynamics, most of which seem to be captured by Newtonian dynamics and flat-space intuition. The waveforms can be qualitatively described in terms of three stages; (i) an infall phase prior to the for","authors_text":"Carlos Herdeiro, Luis Lehner, Miguel Zilh\\~ao, Ulrich Sperhake, Vitor Cardoso","cross_cats":["astro-ph.CO","hep-th"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2012-05-04T20:02:12Z","title":"Collisions of charged black holes"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1205.1063","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:d171bf012c30f22e73b5f3099f43924aae273e8068ae64d5becc3c69fc1424ab","target":"record","created_at":"2026-05-18T03:51:47Z","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":"2eec248c32b9c8827a1fb4003cec7a7881ab1945fea3a4fb27dbe1a4ed04c31d","cross_cats_sorted":["astro-ph.CO","hep-th"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"gr-qc","submitted_at":"2012-05-04T20:02:12Z","title_canon_sha256":"42cdb8523bfa8cc487695bca6bd9b95b90bce8b504a0ad91eb5afc3dd24e2f4c"},"schema_version":"1.0","source":{"id":"1205.1063","kind":"arxiv","version":2}},"canonical_sha256":"29dd97ad1979a34bae4c8fd5fa77fb5cf138467b0c7d7d49914154ade7f4ec2a","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"29dd97ad1979a34bae4c8fd5fa77fb5cf138467b0c7d7d49914154ade7f4ec2a","first_computed_at":"2026-05-18T03:51:47.006987Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T03:51:47.006987Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"/W38tShpm38Ki/N4G1JYI7lyR9/x1mEN4dzWkuoXuGWMbLj1oONzQ03/7zIzTR6eyx97BVSPqnQnpLddj/shAA==","signature_status":"signed_v1","signed_at":"2026-05-18T03:51:47.007689Z","signed_message":"canonical_sha256_bytes"},"source_id":"1205.1063","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:d171bf012c30f22e73b5f3099f43924aae273e8068ae64d5becc3c69fc1424ab","sha256:6a26936ef96478ead658ac03032beccf0f2abbb7521b559db57a62c76e24a3e2"],"state_sha256":"66c86419b5bae1feafa6f06d863954fb79631c8dd3dd633b5be286f6d169ce74"}
