Dark energy, dark matter and the Chaplygin gas
arXiv:gr-qc/0210079
Abstract
The possibility that the dark energy may be described by the Chaplygin gas is discussed. Some observational constraints are established. These observational constraints indicate that a unified model for dark energy and dark matter through the employement of the Chaplygin gas is favored.
