Navarro-Frenk-White Profile

(NFW Profile)
(a dark matter spatial mass distribution function)

The Navarro-Frenk-White Profile (NFW Profile) is a spatial mass distribution function for the internals of Dark Matter Halos, developed from n-body Cosmological simulations run by Navarro, Frenk, and White.

ρ(r) = ————————————
  • r - distance from a center of the halo.
  • ρ(r) - density at r.
  • ρ0 - a density parameter for the halo
  • Rs - a scale parameter for the halo

The distribution has been adopted for use within other models.
