WMAP and the generalized Chaplygin gas
We compare the WMAP temperature power spectrum and SNIa data to models with a generalized Chaplygin gas as dark energy. The generalized Chaplygin gas is a component with an exotic equation of state, p X = − A /ρ α X (a polytropic gas with negative constant and exponent). Our main result is that, res...
