The connection between the cusp-to-core transformation and observational universalities of DM haloes
arXiv:1309.1646Publication · DOI
Approach
The study tests whether converting initially cuspy haloes to cores can reproduce the near-common central surface density and mass enclosed within 300 parsecs.
Main result
The transformation model recovers the surface-density relation; the common enclosed mass follows within the dwarf-galaxy regime. Core densities also carry information about formation epochs.
Scientific implications
The work connects halo regularities to structural evolution rather than treating each empirical relation as independent.
Scope and limitations
These are consequences of the transformation assumptions and the observational relations considered, not proof of one specific feedback mechanism.
