Cold Dark Matter Cusps

the presence of a cusp in the centers of CDM halos is one of the earliest and strongest result derived from cosmological N-body simulations.Dubinski and Carlberg [14] were among the first to investigate the density profiles of CDM halos and found that the inner parts of these simulated halos could be characterized by power law slope.they did not rule out the existence of central cores but noted that these would have to be smaller than resolution of their simulations (~1.4kpc).Subsequent simulation, at higher and higher resolution, made the presence of cores in simulated CDM halos, derived assuming many different sets of cosmological
