Cosmological model of the interaction between dark matter and dark energy

Abstract

In this paper, we test the dark matter-dark energy interacting cosmological model with a dynamic equation of state $w_{DE}(z)=w_0+w_{1}z/(1+z)$, using type Ia supernovae (SNe Ia), Hubble parameter data, baryonic acoustic oscillation (BAO) measurements, and the cosmic microwave background (CMB) observation. This interacting cosmological model has not been studied before. The best-fitted parameters with $1\sigma$ uncertainties are $\delta =-0.022\pm 0.006$, ${\Omega }_{DM}^0=0.213\pm 0.008$, $w_0=-1.210\pm 0.033$ and $w_1=0.872\pm 0.072$ with ${\chi }_{min}^2/dof=0.990$. At the $1\sigma$ confidence level, we find $\delta <0$, which means that the energy transfer prefers from dark matter to dark energy. We also find that the SNe Ia are in tension with the combination of CMB, BAO and Hubble parameter data. The evolution of ${\rho }_{DM}/{\rho }_{DE}$ indicates that this interacting model is a good approach to solve the coincidence problem, because the ${\rho }_{DE}$ decrease with scale factor $a$. The transition redshift is $z_{tr}=0.63\pm 0.07$ in this model.
