Our data are composed of a set of different physical quantities for primordial minihaloes: dark-matter mass ($M_{\\mathrm{dm}}$), gas mass ($M_{\\mathrm{gas}}$), stellar mass ($M_{\\mathrm{star}}$), molecular fraction (${\\mathrm{x_{mol}}}$), metallicity ($Z$), star formation rate (SFR) and temperature. We find that $M_{\\mathrm{dm}}$ and $M_{\\mathrm{gas}}$ are dominant factors for variance, particularly at high re"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1308.6009","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"}
