Abstract
We investigate the constraints on a generalized Chaplygin gas (GCG)model using the gold sample type-Ia supernovae (Sne Ia) data, thenew Supernova Legacy Survey (SNLS) Sne Ia data and the size ofbaryonic acoustic oscillation peak found in Sloan Digital Sky Survey(SDSS). In a spatially flat universe case we obtain, at a 95.4%confidence level, As = 0.76−0.07+0.07 andα = 0.028−0.238+0.322. Our results are consistent withthe ΛCDM model (α = 0), but rule out the standardChaplygin gas model (α = 1).
