Web18 de abr. de 2013 · For comparison we also consider a Navarro-Frenk-White profile. We find that the cored profile is the preferred one, with a shallow central density of rho_H~4x10^7M_s/kpc^3 and a large core radius R_H~10 kpc, as observed in external spirals and in agreement with the mass model underlying the Universal Rotation Curve of … WebIl profilo di Navarro-Frenk-White (profilo NFW) è un modello che descrive la distribuzione spaziale di massa di materia oscura negli aloni oscuri, ossia ipotetiche porzioni esterne di aloni galattici contenenti grandi quantità di materia oscura, derivato da Julio Navarro, Carlos Frenk e Simon White nel 1996 grazie a simulazioni a N-corpi da loro sviluppate.
