An analytical approach to the dwarf galaxies cusp problem.

DE SOUZA R.S. and ISHIDA E.E.O.

Abstract (from CDS):

An analytical solution for the discrepancy between observed core-like profiles and predicted cusp profiles in dark matter halos is studied. We calculate the distribution function for Navarro-Frenk-White halos and extract energy from the distribution, taking into account the effects of baryonic physics processes. We show with a simple argument that we can reproduce the evolution of a cusp to a flat density profile by a decrease of the initial potential energy.
