In this paper, we reveal that this preference is significantly biased by an external low-redshift supernova (low-$z$ SN) sample, which was combined with the Dark Energy Survey SN program (DES-SN) in their Year-Five data release (DESY5). Using the intercept in the SN magnitude-distance relation as a diagnostic for systematics, we find not only large dispersions but also a large discrepanc","authors_text":"Lu Huang, Rong-Gen Cai, Shao-Jiang Wang","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2025-02-06T16:51:39Z","title":"The DESI DR1/DR2 evidence for dynamical dark energy is biased by low-redshift supernovae"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2502.04212","kind":"arxiv","version":5},"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":"sha256:034749ace9b1d400380327374cfb4cc7b0ffaabedb4584d25b040eb9338d8277","target":"record","created_at":"2026-07-05T11:44:00Z","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":"617eb9bea5a9572dad5e359a296f84583b59940b228eda9279f2b47c518b0fb9","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2025-02-06T16:51:39Z","title_canon_sha256":"e48fa0976cd7d0b57e2036bda2f289cf3f05908c9ddf14d975ebf8c7416fb10e"},"schema_version":"1.0","source":{"id":"2502.04212","kind":"arxiv","version":5}},"canonical_sha256":"3311bcf6c05d5dcdb1efc9b921339e01388c215219b3bd5cd081bb1775fb24b2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"3311bcf6c05d5dcdb1efc9b921339e01388c215219b3bd5cd081bb1775fb24b2","first_computed_at":"2026-07-05T11:44:00.901859Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:44:00.901859Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"czWqmhuMxEByPsPeQgiFBrhaABBE8uYBncO1AcZxgKYV9NDvscLFxTbCzBBOlyS+sTlasso9syHf5EJqe8qJAg==","signature_status":"signed_v1","signed_at":"2026-07-05T11:44:00.902340Z","signed_message":"canonical_sha256_bytes"},"source_id":"2502.04212","source_kind":"arxiv","source_version":5}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:034749ace9b1d400380327374cfb4cc7b0ffaabedb4584d25b040eb9338d8277","sha256:75908171ffc6b24d539e059b24b2358850c8320de688947b7dd792146797fd3f"],"state_sha256":"e90be496d39e57e93e6e3d860ed27b575710acf6d30954522e6d2d1a10f06fd6"}
