One model is the SCDM model, and the others are six low-density models with the density parameter $\\Omega=0.1$, 0.2 or 0.3 and with or without a cosmological constant $\\Lambda=1-\\Omega$. We find that the velocity dispersion profiles depend both on $\\Omega$ and on $\\Lambda$. For $\\Lambda=0$, the profiles are steeper in a lower-$\\Omega$ model than in a higher-$\\Omega$ one. The cosmological constant significantly weakens the dependence on $\\Omega$: the difference in the profile dis"},"claims":{"count":0,"items":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"astro-ph/9508104","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"}
