   1. N-body simulations.
   2. Navarro-Frenk-White profile (NFW profile).
   3. Universal structure of dark matter haloes over a mass range of 20 orders of magnitude: Jie Wang (NAOC), Sownak Bose (CfA), Carlos S. Frenk, et al. arXiv, 2020, Sep02 39 pages: Research: On dark halos from pure dark matter simulations. Their universal structure does not seem to agree with Wagner 2020: Self-gravitating dark matter gets in shape which gives a analytic universal structure (i.e., the Wagner profile). It's closer to the Einasto profile than the Navarro-Frenk-White profile (NFW profile). On gravitational mechanics (GrM). / keywords_cosmology.html.

It sounds like I'm tracking work of Subrahmanyan Chandrasekhar (1910--1995), but probably badly. Let us use this paper to define gravitational mechanics (GrM). / keywords_cosmology.html.
