We measure the auto- and cross-correlations between galaxy and cluster samples, from which we extract the effective biases and study the shot noise properties. We model the non-Poissonian shot noise by introducing an effective number density of tracers and fit for this quantity. We find that we can only describe the cross-correlation of galaxies and galaxy clusters, as well as the auto-correlation of galaxy cluste","authors_text":"Ben Hoyle, Georg Sauerwein, Jochen Weller, Kerstin Paech, Matteo Costanzi, Nico Hamaus, Steffen Hagstotz, Tommaso Giannantonio","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2016-12-06T21:03:31Z","title":"Cross-correlation of galaxies and galaxy clusters in the Sloan Digital Sky Survey and the importance of non-Poissonian shot noise"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1612.02018","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":"sha256:1c3767ea8a230c21a996268a7fc12baff1f7c2162e14af04a7574775aadeb8bc","target":"record","created_at":"2026-05-18T00:39:39Z","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":"898163a490addbcf1976cc863bc98fb85629730fc3997d42b5237bd84679c4b1","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2016-12-06T21:03:31Z","title_canon_sha256":"b89f16d8be65fa34d7f98ede6f1be9b3d7ac20f262492cb62f4a9c4ee3a65167"},"schema_version":"1.0","source":{"id":"1612.02018","kind":"arxiv","version":1}},"canonical_sha256":"b0c536feef4baef7184da9c8982c0d1765247d06bd72646021776cc69d46fd78","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b0c536feef4baef7184da9c8982c0d1765247d06bd72646021776cc69d46fd78","first_computed_at":"2026-05-18T00:39:39.502700Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:39:39.502700Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Lkz7wr5QG/I+VcIZelgMGD5TSMFOr2vuu6vSppdPDtmlP2QqHTrr7lsYxJ5y3BfWBADH8CRFqpixs7hBFJ7sDA==","signature_status":"signed_v1","signed_at":"2026-05-18T00:39:39.503714Z","signed_message":"canonical_sha256_bytes"},"source_id":"1612.02018","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:1c3767ea8a230c21a996268a7fc12baff1f7c2162e14af04a7574775aadeb8bc","sha256:b02288236a431a50993bc2478838fae6c0b72799a8a65a96e847334ac62f8950"],"state_sha256":"1f077a7b623b2d67c54a80f3c99f721a85d192b12ed7ddcc42fc98cbe003f7ec"}
