In this paper we develop and test a new statistic based on anisotropies in the measured galaxy power spectrum, which is independent of galaxy bias and matches the matter power spectrum shape on large scales. The amplitude provides a constraint on the derivative of the linear growth rate through f.sigma_8. This demonstrates that spectroscopic galaxy surveys offer many of the same advantages as weak lensing surveys, in that they both use gala","authors_text":"Martin White, Will J Percival","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph","submitted_at":"2008-07-31T20:00:09Z","title":"Testing cosmological structure formation using redshift-space distortions"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"0808.0003","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":"sha256:9b5453bba560eee7e3896c4b15ea9b61398d4a1f6516bd285c8feb3bf05bc75c","target":"record","created_at":"2026-07-04T17:12:04Z","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":"e229815c88ff94579bb4d8122f545d385e13e96ae641c8dcc239b69f8d9e21a7","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph","submitted_at":"2008-07-31T20:00:09Z","title_canon_sha256":"917c19126ca9e3aa3fdb10f3fc9e0187f080434e38f6fe85078e8048c5cb13ae"},"schema_version":"1.0","source":{"id":"0808.0003","kind":"arxiv","version":2}},"canonical_sha256":"ed878d1d3a0b7d298084602e53b2f929c971f2fe083595220949ac5efc1dfc88","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ed878d1d3a0b7d298084602e53b2f929c971f2fe083595220949ac5efc1dfc88","first_computed_at":"2026-07-04T17:12:04.491370Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T17:12:04.491370Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"5hnZRGV52CyzjbRuF+m1ndMZB9Eu5BmvIQvdY0ikVOrtsW28YYzV43bP8E7kSv/T5aAuC2Vgd89u9X6ninNbDA==","signature_status":"signed_v1","signed_at":"2026-07-04T17:12:04.491739Z","signed_message":"canonical_sha256_bytes"},"source_id":"0808.0003","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:9b5453bba560eee7e3896c4b15ea9b61398d4a1f6516bd285c8feb3bf05bc75c","sha256:49bae3155a8879220c4d768fdaedce38b09b6f323b2f00852822a41363c8a5e2"],"state_sha256":"73fcba62eb62a97a5ff2578258df1088d830f07a2047d031e4cf07f212d36cd1"}
