Testing the (generalized) Chaplygin gas model with the Lookback time-Redshift data

Abstract

The Chaplygin gas (CG) and the generalized Chaplygin gas (GCG) models, proposed as candidates of the unified dark matter-dark energy (UDME), are tested with the look-back time (LT) redshift data. We find that the LT data only give a very weak constraint on the model parameter. However, by combing the LT with the baryonic acoustic oscillation peak, we obtain, at the 95.4% confidence level, $0.68\le A_c\le 0.82$ and $0.59\le h\le 0.65$ for the CG model, and $0.67\le A_s\le 0.89$ and $-0.29\le \alpha \le 0.61$ for the GCG model. This shows that both the CG and the GCG are viable as a candidate of UDME. Within the GCG model, we also find that the Chaplygin gas model ($\alpha =1$) is ruled out by these data at the 99.7% confidence level.
