Abstract:
We investigate a spatially flat Friedmann-Robertson-Walker (FRW) cosmological model with cold dark matter coupled to a modified holographic Ricci dark energy through a general interaction term linear in the energy densities of dark matter and dark energy, the total energy density and its derivative 1. Using the statistical method of X2-function for the Hubble data, we obtain H0 = 73.6km/sMpc, ωs = -0.842 for the asymptotic equation of state and zacc = 0.89. The estimated values of Ωc0 which fulfill the current observational bounds corresponds to a dark energy density varying in the range 0.25R < ρx < 0.27R. © 2012 American Institute of Physics.
