The Ne VIII 770 line is at $\\sim 3\\sigma$ significance. In both instances, the NeVIII is found to be tracing gas with $T \\gtrsim 10^5$ K, predominantly collisionally ionized, with moderate densities of $n_{H} \\lesssim 10^{-4}$ $cm^{-3}$, sub-solar metallicities and total hydrogen column densities of $N(H) \\gtrsim 10^{19}$ $cm^{2}$. In the z = 0.61907 absorber, the low, intermediate ions and O VI are consistent"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1706.04325","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"}
