Description

There are competing claims that the dark matter may have already been discovered through the annihilation of cold dark matter or the decay of warm dark matter. Both hypotheses result in indistinguishable model universes on the large scales probed by temperature anisotropies in the microwave background radiation and the clustering of galaxies. The identity of the dark matter, however, manifests itself in the properties of small, dwarf galaxies. I will discuss predictions from cosmological simulations for the properties of these galaxies for different types of dark matter and discuss whether astronomical observations can, in principle, distinguish amongst them.
