Crossing the phantom divide with dissipative normal matter in the Israel–Stewart formalism
A phantom solution in the framework of the causal Israel–Stewart (IS) formalism is discussed. We assume a late time behavior of the cosmic evolution by considering only one dominant matter fluid with viscosity. In the model it is assumed a bulk viscosity of the form ξ=ξ0ρ1/2, where ρ is the energy d...
