Why it is important: The dark matter haloes that envelope all galaxies are predicted to have similar shapes: a ‘cuspy’ density profile that increases steeply at the center. Here, a new model is proposed to explain why the haloes of many dwarf galaxies instead have a ‘core’ profile with a relatively constant density in their central regions.
