Dynamical Dark Energy Properties Hidden in the Dark Matter Halos and
  Voids
  In this paper, we analysed the halos and voids properties of a GR-based
N-body simulation carried out at redshifts z= 0.0 and z= 0.8 as differences
between dynamical dark energy models (namely PL and CPL) with respect to LCDM.
Analysing the halos demonstrates that both models, PL and CPL, behave like
LCDM, despite the velocity dispersion of halos was more sensitive to the
dynamical dark energy model. In addition, a void finder was developed to
extract the properties of voids from simulated data. Further statistical model
on voids confirms that the PL model produces larger voids. In summary, our
novel simulation demonstrates void properties are better than halo properties
in discriminating between dark energy models. Hence, the results suggest to
make more use of the properties of voids in future studies of discriminating
dynamical dark energy models.
