Dynamics of Dark-Matter Cusps

  • Conference paper
Dark Matter in Astro- and Particle Physics

Abstract

Formation and disruption of dark-matter cusps are reviewed. Accumulation of baryons at the center of a halo can displace the dark matter, converting singular density cusps into low-density cores. The displaced mass can be of order ~ 10M ● with M ● the mass of the infailing population. If M ● is identified with the masses of the black holes currently observed at the centers of bright galaxies, predicted core radii are ~ a few х 102 pc. Other mechanisms, such as early mass outflow, may explain the large dark-matter cores in dwarf and low-surface-brightness galaxies. Predictions of dark matter annihilation radiation from the center of the Milky Way galaxy are shown to be strongly dependent on the galaxy’s merger history.
