We account for the problem of peaks within peaks; when considering a halo of a given mass we ensure that this halo is not a part of a larger virialized halo. For halos that represent high-sigma fluctuations we recover the usual result that such halos preferentially lie within highly overdense regions; in the limit of very low-sigma fluctuations, on the other hand, we show that halos tend t","authors_text":"Rennan Barkana (Tel Aviv University)","cross_cats":[],"headline":"","license":"","primary_cat":"astro-ph","submitted_at":"2002-12-19T21:24:00Z","title":"A Model For Infall Around Virialized Halos"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"astro-ph/0212458","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":"sha256:504b8350b819b8132e1c8a3923942be1fc511c72184ee9c00cd6b9d19235b443","target":"record","created_at":"2026-07-04T16:31:27Z","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":"5f185e8ca2d682c5257ca33a3fbf47919531ae7b4a690d3bb503d0fc9936e5b0","cross_cats_sorted":[],"license":"","primary_cat":"astro-ph","submitted_at":"2002-12-19T21:24:00Z","title_canon_sha256":"91fbe03e9e6eca8ea459c8651a6462c1c79ac86ffad938f44cc7afcecb2ff130"},"schema_version":"1.0","source":{"id":"astro-ph/0212458","kind":"arxiv","version":2}},"canonical_sha256":"0a69a85ee5c1053a727881fbedea2d16e8cb0eab3c4312be1831b9a3bbe6b4d8","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"0a69a85ee5c1053a727881fbedea2d16e8cb0eab3c4312be1831b9a3bbe6b4d8","first_computed_at":"2026-07-04T16:31:27.056132Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T16:31:27.056132Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"oTGsL5BQgQ88e7Xlli+x16oK72gtGNKABm+wumRhwULfBh0wpYUG3pTU+/f9tXwmlVj6GQvzmDJrZR8MWYsiAw==","signature_status":"signed_v1","signed_at":"2026-07-04T16:31:27.056605Z","signed_message":"canonical_sha256_bytes"},"source_id":"astro-ph/0212458","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:504b8350b819b8132e1c8a3923942be1fc511c72184ee9c00cd6b9d19235b443","sha256:3d1b02b32ccbdb2c9edaf0b158ead322b7432717a0675104435c996c1a8bc286"],"state_sha256":"3f96fca8a66e9beb4c46d25a37000060312853037304a5032ab543463e40ccfd"}
