The Phase-Space Structure of Cold Dark Matter in the Universe
  A novel method allowing to compute density, velocity and other fields in
cosmological N--body simulations with unprecedentedly high spatial resolution
is described. It is based on the tessellation of the three-dimensional manifold
representing cold dark matter in six-dimensional phase space. The density,
velocity and other fields are computed by projecting the tessellation on
configuration space. The application of this technique to cosmological N--body
simulations in LambdaCDM cosmology reveals a far more elaborate cosmic web then
dot plots or self--adaptive SPH. In addition, this method allows to uniquely
define physical voids and identify and study the caustic surfaces directly.
