One possibility is that the repeating FRBs are produced by a new-born magnetar, which also powers the radio nebula. If so, the magnetar may produce $\\gamma$-ray emission due to magnetic dipolar spin-down. The luminosity depends on the magnetar spin parameters and age. We process the eight-year Fermi LAT data at the position of FRB 121102 and place an energy flux upper limit of $\\sim 10^{-11} \\","authors_text":"Binbin Zhang, Bing Zhang","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2017-05-11T15:29:27Z","title":"Repeating FRB 121102 : Eight-year Fermi-LAT Upper Limits and Implications"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1705.04242","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:f8bbf29df4bff09f316738d2e12305450d9691c9256c9fe9bf3b49802aaa7cbc","target":"record","created_at":"2026-05-18T00:41:06Z","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":"0b37bd421a8cc122ae6e7eb42e1b8f2e2b786abab6867395369b7ba10be75234","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2017-05-11T15:29:27Z","title_canon_sha256":"22ea39a16f5ac69791c4b94705f74a4f389f1f580b60df89f2588a0f9a9fccf1"},"schema_version":"1.0","source":{"id":"1705.04242","kind":"arxiv","version":2}},"canonical_sha256":"eec7b2f4a284ba24f58eeed9dfc3025fb2cad26c6d21a54f333dd4dabc15bddd","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"eec7b2f4a284ba24f58eeed9dfc3025fb2cad26c6d21a54f333dd4dabc15bddd","first_computed_at":"2026-05-18T00:41:06.975128Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:41:06.975128Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"QRG9cnqAs+nGxApsvZFpJXRqdpf82NIQNZX4NBlpY7z7kUwB1dPaBEuauhl/UpFx1aw/du2TfoOMxo9uwVvtBg==","signature_status":"signed_v1","signed_at":"2026-05-18T00:41:06.975770Z","signed_message":"canonical_sha256_bytes"},"source_id":"1705.04242","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f8bbf29df4bff09f316738d2e12305450d9691c9256c9fe9bf3b49802aaa7cbc","sha256:f2f5050d13f38f9e343f71f52e0d690b06f8a139bd469c705adc0a3f297d4c3b"],"state_sha256":"970124b2c780643fad2948dc4117ffa1e83ccd68f22937db8c4a10ac77fc999f"}
