Testing the interaction of dark energy to dark matter through the
  analysis of virial relaxation of clusters Abell Clusters A586 and A1689 using
  realistic density profiles
  Interaction between dark energy and dark matter is probed through deviation
from the virial equilibrium for two relaxed clusters: A586 and A1689. The
evaluation of the virial equilibrium is performed using realistic density
profiles. The virial ratios found for the more realistic density profiles are
consistent with the absence of interaction.
