It is realized in two-stage inflation where a non-inflationary stage is sandwiched by the two inflationary stages. In this case, smaller PBHs form when the comoving scale of interest re-enters the horizon during the break period, and larger PBHs form when the scale re-enters the horizon after inflation. This mechanism may realize both reheating of the universe through the evaporation of ultralight PBHs formed during the break stage and the dar","authors_text":"Misao Sasaki, Xinpeng Wang, Ying-li Zhang","cross_cats":["gr-qc","hep-ph"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2025-05-14T12:32:18Z","title":"The Dual Primordial Black Hole Formation Scenario"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2505.09337","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":"sha256:708d7aa24a40bab28170b749165221e8b429d065cac0797430633304e1ad9f76","target":"record","created_at":"2026-07-05T11:03:06Z","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":"3b4c8d1bcb9fbcaa6296fe7f115f341895b1e2e90c2f72e110528296abdc7d9d","cross_cats_sorted":["gr-qc","hep-ph"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2025-05-14T12:32:18Z","title_canon_sha256":"ccd34fd41ad88ae8c02414f5af00f130817df49536f7f313d3f97b0b9742cf59"},"schema_version":"1.0","source":{"id":"2505.09337","kind":"arxiv","version":1}},"canonical_sha256":"b2a40933e09a4c9109c24c87bcb65b976cc4fbe342461830724b982dc1e4d33c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b2a40933e09a4c9109c24c87bcb65b976cc4fbe342461830724b982dc1e4d33c","first_computed_at":"2026-07-05T11:03:06.673120Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:03:06.673120Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"qB7DGMOQKrMSqU80qbNV1nko7z9zjSDbntH2jnEsbuH8qIv60O2AJaErnnjlRXS1ZsgkEmVkWiDCdxiPJUMKCw==","signature_status":"signed_v1","signed_at":"2026-07-05T11:03:06.673581Z","signed_message":"canonical_sha256_bytes"},"source_id":"2505.09337","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:708d7aa24a40bab28170b749165221e8b429d065cac0797430633304e1ad9f76","sha256:f6f285f044ac3a1f022e339c0a738de61a49448cb1211375241c6e3f7634368e"],"state_sha256":"8753dea67f58a68a1f4ee999d93755bd606e66172a95519d0e745952344a8d87"}
