The systems most likely to be observed with pulsar timing arrays (PTAs) will have particularly high masses ($\\gtrsim 10^9 M_\\odot$), long periods ($T_{\\rm orb} \\gtrsim 1$ yr), and be in the local universe ($z \\lesssim 1$). These features are also the most favorable for bright electromagnetic counterparts, which should be easily observable with existing ground- and space-based telescopes. Wide-field X-ray observatories such as ISS-Lobster will provide independent candidates that can be used to lower t"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1411.3994","kind":"arxiv","version":1},"verdict":{"id":null,"model_set":{},"created_at":null,"strongest_claim":"","one_line_summary":"","pipeline_version":null,"weakest_assumption":"","pith_extraction_headline":""},"references":{"count":0,"sample":[],"resolved_work":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57","internal_anchors":0},"formal_canon":{"evidence_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"author_claims":{"count":0,"strong_count":0,"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"builder_version":"pith-number-builder-2026-05-17-v1"}
