Abstract: Spiral galaxies are known to present an important mass discrepancy between their dynamical and visible masses. The commonly accepted hypothesis is to assume a spherical halo of unseen matter in addition to the stars and gas. The exact density distribution of these halos has become an important issue. N-Body simulations of cold dark matter cosmological evolution have now reached sufficient resolution to predict the dark halos density profiles down to the inner parts of spiral galaxies and almost always show dense cuspy cores.
