For instance the effective equation of state in braneworld models can be both quintessence-like (w_0 \\geq -1) as well as phantom-like (w_0 \\leq -1). Models with w_0 \\geq -1 (w_0 \\leq -1) are referred to as Brane 2 (Brane 1) and correspond to complementary embeddings of the brane in the bulk. (The equation of state in Brane 1 can successfully cross the `phantom divide' at w = -1.) In this paper we compare the predictions of braneworld models to two recently released supernova data sets: the `Gold' data (Riess et al, 2004) and","authors_text":"Ujjaini Alam, Varun Sahni","cross_cats":["gr-qc","hep-ph"],"headline":"","license":"","primary_cat":"astro-ph","submitted_at":"2005-11-16T08:02:09Z","title":"Confronting Braneworld Cosmology with Supernova data and Baryon Oscillations"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"astro-ph/0511473","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":"sha256:55808209a25d5d78ab5fb1bf87fddefe870ce933062c01bd395a8fa1987e7ab2","target":"record","created_at":"2026-07-04T17:15:27Z","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":"19628b4862cb4daeab4789dd5be54127a71757c2a0e58aa05ebed9c314af78aa","cross_cats_sorted":["gr-qc","hep-ph"],"license":"","primary_cat":"astro-ph","submitted_at":"2005-11-16T08:02:09Z","title_canon_sha256":"ba8ca19e7265a820f61ed77f7791ae3ac4088c5f16aee5c33c752e13a42c806a"},"schema_version":"1.0","source":{"id":"astro-ph/0511473","kind":"arxiv","version":2}},"canonical_sha256":"3530be6895275e9997be54ef46da6b0822d59da77edf28c2b39e00cc36650165","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"3530be6895275e9997be54ef46da6b0822d59da77edf28c2b39e00cc36650165","first_computed_at":"2026-07-04T17:15:27.328202Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-04T17:15:27.328202Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"cFlxiPsn/o4DAnFpOGq0q7TgC3ce/c687ojzYZeccKmqIMi5V4h2EbuuLCZggOEQyJqpJC8B+Kk0+mkP/ze6Aw==","signature_status":"signed_v1","signed_at":"2026-07-04T17:15:27.328644Z","signed_message":"canonical_sha256_bytes"},"source_id":"astro-ph/0511473","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:55808209a25d5d78ab5fb1bf87fddefe870ce933062c01bd395a8fa1987e7ab2","sha256:63a71ead242b106e2dc79f9013552482639eed97e023de33e44e4b4ab9eefdb1"],"state_sha256":"f4af62864a2c714f6b8e4d602bc124b4ee88a1f94e118f80d4b83fc102baa6cf"}
