Is the cosmological dark sector better modeled by a generalized Chaplygin gas or by a scalar field?
Abstract Both scalar fields and (generalized) Chaplygin gases have been widely used separately to characterize the dark sector of the universe. Here we investigate the cosmological background dynamics for a mixture of both these components and quantify the fractional abundances that are admitted by...
