Advances in Astronomy, 2010•Wiley Online LibraryThis paper gives an overview of the attempts to determine the distribution of dark matter in
low surface brightness disk and gas‐rich dwarf galaxies, both through observations and
computer simulations. Observations seem to indicate an approximately constant dark matter
density in the inner parts of galaxies, while cosmological computer simulations indicate a
steep power‐law‐like behaviour. This difference has become known as the “core/cusp
problem,” and it remains one of the unsolved problems in small‐scale cosmology.
