The paper by A. Burkert explores the structure of dark matter halos in dwarf galaxies, addressing the contradiction between observed flat central density profiles and cosmological simulations predicting self-similar haloes with central density cusps. Burkert argues that dark matter haloes in dwarf spiral galaxies form a one-parameter family with self-similar density profiles, which can be explained by the standard cold dark matter (CDM) model. The observed global halo parameters are coupled through simple scaling relations, suggesting that all haloes formed from density fluctuations with the same primordial amplitude. The finite central halo densities correlate with other global parameters, ruling out scenarios where flat halo cores formed through violent dynamical processes in the baryonic component. These findings provide important insights into the origin and nature of dark matter in dwarf galaxies. The paper also discusses the implications of these scaling relations for cosmological models and the potential for dynamical processes affecting the inner structure of DM haloes.The paper by A.
