Scientific paper

We performed cosmological simulations based upon both a cold dark matter
(CDM) and a warm dark matter (WDM) model. The focus of our investigations lies
with selected spatial and kinematic properties of substructure halos (subhalos)
orbiting within host halos, that form in both dark-matter cosmologies. We aim
at using the dynamics of the subhalos as a probe of the respective cosmology.
