In this regime, foreground contamination to the temperature map produces significant lensing biases, which cannot be fully controlled by multi-frequency component separation, masking or bias hardening. In this letter, we split the standard CMB lensing quadratic estimator into a new set of optimal \"multipole\" estimators. On large scales, these multipole estimators reduce to the known magnification and shear estimators, and a new shear B","authors_text":"Emmanuel Schaan, Simone Ferraro","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2018-04-17T17:59:22Z","title":"Foreground-immune CMB lensing with shear-only reconstruction"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1804.06403","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":"sha256:3e05184d98e583a641669652fd9a9cb5d4aa26082ff4dce7f4f18f2bb69bc172","target":"record","created_at":"2026-05-17T23:45:58Z","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":"75b77af22ee30fb5b11423d30868625596d79f7291e6177201041c5da292aac2","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.CO","submitted_at":"2018-04-17T17:59:22Z","title_canon_sha256":"295e15a8b028c511803934ec33498d2cefd15372e420452d1d2306e2cbea72b6"},"schema_version":"1.0","source":{"id":"1804.06403","kind":"arxiv","version":2}},"canonical_sha256":"99e4a7a9cf6b2738aa6ae811caea92325ddfa1140ca880f686a3c1231d7e2888","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"99e4a7a9cf6b2738aa6ae811caea92325ddfa1140ca880f686a3c1231d7e2888","first_computed_at":"2026-05-17T23:45:58.141242Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:45:58.141242Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"cGoT+ZttjfxMjyW6brT99yqnh46Pg1cnBw1PRt0E8UDXsyTwqWeOsE9MNcy/fCAwoYcX3Ieqqhj9ZtHvuvCtBQ==","signature_status":"signed_v1","signed_at":"2026-05-17T23:45:58.141919Z","signed_message":"canonical_sha256_bytes"},"source_id":"1804.06403","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:3e05184d98e583a641669652fd9a9cb5d4aa26082ff4dce7f4f18f2bb69bc172","sha256:6e76873d49f070248d9bb6c797216a753cf0bd6363cc0e7867c881316d229d6b"],"state_sha256":"429bb015904d8285ad19b061ca92a49163296301dd211d1bba06c11cc9979ed4"}
