| 英文摘要 | We consider a new generalized Chaplygin gas model that includes the original Chaplygin gas model as a special case. In such a model the generalized Chaplygin gas evolves as from dust to quiescence or phantom. We show that the background evolution for the model is equivalent to that for a coupled dark energy model with dark matter. The constraints from the current type la supernova data favour a phantom-like Chaplygin gas model. (c) 2007 Elsevier B.V. All rights reserved. |
