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 cosmological N-body simulations run by Navarro, Frenk, and White.

            ρ0
ρ(r) = ————————————
       r/Rs(1+r/Rs)2

The distribution has been adopted for use within other models.
