Dissipative $$\varLambda $$ Λ CDM model with causal sign-switching bulk viscous pressure

Abstract Extending the standard $$\varLambda $$ Λ CDM model by considering dissipative effects within a causal viscous framework, and obtaining an analytical solution for the Hubble parameter remains a challenge in the literature. In this work, we resolve this dilemma by deriving a complete and orig...
