Abstract
Using the data coming from the new 182 gold type Ia supernova samples, the shift parameter of the cosmic microwave background given by the three-year Wilkinson Microwave Anisotropy Probe observations, and the baryon acoustic oscillation measurement from the Sloan digital sky survey, H(z) and lookback time measurements, we have performed a statistical joint analysis of the interacting holographic dark energy model. Consistent parameter estimations show us that the interacting holographic dark energy model is a viable candidate for explaining the observed acceleration of our universe.
