Accelerating and Decelerating Bianchi Type VI0 Cosmological Models with Wet Dark Fluid in General Relativity

Abstract

The Bianchi Type VI₀ Universe filled with dark energy from a Wet dark fluid has been considered. A new equation of state for the dark energy component of the Universe has been used. It is modeled of the equation of state p=γ(ρ-ρ_*) which can describe a liquid, for example water. The exact solutions to the corresponding field equations are obtained in quadrature form. The solutions for constant deceleration parameter have been studied in detail for power-law and exponential forms both.
