To this end, we compare two low density branches propagated through a common high density extension and confront them with direct NICER mass-radius posteriors, a lower bound on the maximum mass, and an effective constraint on $\\Lambda_{1.4}$. We find that the observable predictions of the two branches remain strongly overlapping, while the NICER-informed posterior still induces a nontrivial constraint on th","authors_text":"Federico Nola","cross_cats":["astro-ph.HE"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nucl-th","submitted_at":"2026-06-05T17:55:03Z","title":"NICER Constraints on Low density Interpolation and High density Continuation in Neutron Star Equations of State"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2606.07731","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":"sha256:867d56e1e6a18a53607873c001de5096f3a3c572ff6a3a3ac7dc5b48b09c82fe","target":"record","created_at":"2026-06-09T01:04:50Z","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":"6f0cb14e11f7ccb12b8ebc254f955da0e0841df91223ce82b51a39c136ea6622","cross_cats_sorted":["astro-ph.HE"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"nucl-th","submitted_at":"2026-06-05T17:55:03Z","title_canon_sha256":"9d30e03fc52b88783509f7adef1909ac98d44cfcc2d228656f83bdd756b19e17"},"schema_version":"1.0","source":{"id":"2606.07731","kind":"arxiv","version":1}},"canonical_sha256":"a141db275e384a7f68007d1443dc2664f0dc9498636d58c8069249936091324e","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a141db275e384a7f68007d1443dc2664f0dc9498636d58c8069249936091324e","first_computed_at":"2026-06-09T01:04:50.620406Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-09T01:04:50.620406Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"rgvBezliILihiOM4ahOQOLnmCGCzGpQWgYSyGsYmkKS8LezCfjwv00hYTPPUrZIZ5tY5bvFTEhpx9zJWv0p5AQ==","signature_status":"signed_v1","signed_at":"2026-06-09T01:04:50.620816Z","signed_message":"canonical_sha256_bytes"},"source_id":"2606.07731","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:867d56e1e6a18a53607873c001de5096f3a3c572ff6a3a3ac7dc5b48b09c82fe","sha256:a7ffbe37bb2261485620bebf787b4c72756c1e9c0636bdc3c007099047a7932d"],"state_sha256":"0cda0c4d5843281460799327c1cc0a16acb17af64d347c5195f7d7936c3df6cc"}
