Abstract
We investigate observational constraints on the generalized Chaplygin gas (GCG) model as the unification of dark matter and dark energy from the latest observational data: the Union SNe Ia data, the observational Hubble data, the SDSS baryon acoustic peak and the five-year WMAP shift parameter. The result is obtained that the best-fit values of the GCG model parameters with their confidence level are A s=0.73 +0.06−0.06 (1σ) +0.09−0.09 (2σ), α=−0.09 +0.15−0.12 (1σ) +0.26−0.19 (2σ). Furthermore, in this model, we can see that the evolution of equation of state (EOS) for dark energy is similar to quiessence, and its current best-fit value is w 0de=−0.96 with the 1σ confidence level −0.91≥w 0de≥−1.00.
