However, the present-day environments of the descendants of first quasars is not well understood and it is not known if they live in massive galaxy clusters or more isolated galaxies at $z=0$. We use a dark matter-only realization (BTMassTracer) of the BlueTides cosmological hydrodynamic simulation to study the halo properties of the descendants of the most massive black holes at $z=8$. We find that the descendants of the quasars with most massive black holes are not amongst the most massive h","authors_text":"Ananth Tenneti, Rupert Croft, ThomasJae Garcia, Tiziana Di Matteo, Yu Feng","cross_cats":["astro-ph.CO"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.GA","submitted_at":"2017-08-10T20:27:21Z","title":"The descendants of the first quasars in the BlueTides simulation"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1708.03373","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":"sha256:8bfc21503a0c37e04eddb88cbdbe034a4c388e2cf631f08eaaa5747bff3e82f5","target":"record","created_at":"2026-05-18T00:27:46Z","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":"e0bb85cfce173556be3f327023e6014f750c0858daa1e84b45afc2396230140f","cross_cats_sorted":["astro-ph.CO"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.GA","submitted_at":"2017-08-10T20:27:21Z","title_canon_sha256":"eeab0ad1fdf8d4af5b3c521dc023e294b3d56a302663ab1a709eb8f6d030c1d7"},"schema_version":"1.0","source":{"id":"1708.03373","kind":"arxiv","version":1}},"canonical_sha256":"c8b0fd47246dce8bcb0f92b83673c11bc41f2049db7cd987fc06729b29afacfb","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"c8b0fd47246dce8bcb0f92b83673c11bc41f2049db7cd987fc06729b29afacfb","first_computed_at":"2026-05-18T00:27:46.010126Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:27:46.010126Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"UrlADaAehiKwJt/MD47MUbzjCn3Epm/7EbG4GpQf34DD6MKqpp7U/9NzaxJ40sw/OtLFvKjsd3pMIDQRrRSIBQ==","signature_status":"signed_v1","signed_at":"2026-05-18T00:27:46.010677Z","signed_message":"canonical_sha256_bytes"},"source_id":"1708.03373","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:8bfc21503a0c37e04eddb88cbdbe034a4c388e2cf631f08eaaa5747bff3e82f5","sha256:e22b71c352ab137e873b94fadf46936557c5e5503a7f784c3e9da832e651845f"],"state_sha256":"0952f67da9d876a211998c6b9e501dee5d161145112277955867dbc08fc9ec66"}
