    Sammanfattning : It was previously found that the density profile of dark matter halos is well-fit by a universal, smooth function over a vast range of masses and redshifts, named the Navarro-Frenk-White (NFW) profile after its discoverers. Despite its impressive goodness of fit, the NFW model remains an approximation of the density profile of realistic halos. LÄS MER
