High-precision measurements of the binary parameters allow them to send the signal ~ $10^4$ years before they themselves observe the merger signal. Using the SKA, we might receive ~ $10^4$ bits of data, transmitted from 40 Mpc distance with the output power of ~ 1 TW. We also discuss related topics for GW170817 and mention potential roles of future gravitational wave detectors in relation to this transmission scheme.","authors_text":"Naoki Seto, Yuki Nishino","cross_cats":["gr-qc"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2018-07-16T18:00:02Z","title":"The Search for Extra-Galactic Intelligence Signal Synchronized with a Binary Neutron Star Merger"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1807.06024","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:c7b6acc040431ab821ff5122113969c4be9d559a9a4833d07068245e4bab3fd0","target":"record","created_at":"2026-05-17T23:50:49Z","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":"1eb5837e59093bccf55140ef7d56ef77669b476ca6fdbfcb3be2b9fe6a1a9ed1","cross_cats_sorted":["gr-qc"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"astro-ph.HE","submitted_at":"2018-07-16T18:00:02Z","title_canon_sha256":"d108369613c8eb3e70f689d4a5536b80a9828f21f3979d5818abf206a46552d0"},"schema_version":"1.0","source":{"id":"1807.06024","kind":"arxiv","version":2}},"canonical_sha256":"a1ee7dc88fcbc4cbdecfa454c56bb585c3a5a94d1e447148468200aaa10704f0","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"a1ee7dc88fcbc4cbdecfa454c56bb585c3a5a94d1e447148468200aaa10704f0","first_computed_at":"2026-05-17T23:50:49.068354Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:50:49.068354Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"adU5I1X2aHmpvs2/Ssu1IuPiQZH6cXa1Cu6oNcGDIcBnEe8e9qethFRxycgQZO6UDuqr5YtwJY86WLmq0JINAA==","signature_status":"signed_v1","signed_at":"2026-05-17T23:50:49.068936Z","signed_message":"canonical_sha256_bytes"},"source_id":"1807.06024","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c7b6acc040431ab821ff5122113969c4be9d559a9a4833d07068245e4bab3fd0","sha256:98b317cc24bb74278e94489260c1d39d8c3f8f7a777bfd31db7d2e2e2a1af17f"],"state_sha256":"227a076e8aa536bf3f9c48cce2198ce2ecc5a352d364a954afde6408a57c4e71"}
