Non Cuspy Galactic Halos from Scalar Field Dark Matter

Description
Summary:The Lambda Cold Dark Matter model has recently shown an enormous predictive power. Nevertheless, the CDM paradigm predicts a density profile which corresponds to the Navarro-Frenk-White profile which is cusp and singular in the center of the galaxies. However, observations in LSB galaxies show a density profile which seems to follow an almost constant density profile. In this work we show that a flat central density profile naturally arises within the scalar field dark matter hypothesis. This adds evidence in favor that the cold dark matter in galaxies can be identified with the scalar field.
