For central galaxies with inner compactness $\\Sigma_{\\rm 1kpc} \\sim 10^{9-9.4}M_{\\odot} {\\rm kpc}^{-2}$, the quenched fraction $f_{q}$ is strongly correlated with $\\Sigma_{\\rm 1kpc}$ with only weak halo mass $M_{\\rm h}$ dependence. However, at higher and lower $\\Sigma_{\\rm 1kpc}$, sSFR is a strong function of $M_{\\rm h}$ and mostly independent of $\\Sigma_{\\rm 1kpc}$. In other words, $\\Sigma_{\\"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1406.5372","kind":"arxiv","version":3},"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"}
