Dissipative CDM model with causal sign-switching bulk viscous pressure
Vishnu A Pai, Sarath N, Titus K Mathew
Extending the standard CDM model by considering dissipative effects within a causal viscous framework, and obtaining an analytical solution for the Hubble parameter remains a ch…

Bulk viscous late acceleration under near equilibrium conditions in f(R, T) gravity with mixed matter
Vishnu A Pai, Titus K Mathew
Various studies have shown that the late acceleration of the universe can be caused by the bulk viscosity associated with dark matter. But recently, it was indicated that a cosmolo…

Near Equilibrium Constraints on Bulk Viscous Models in Gravity
Vishnu A Pai, Titus K Mathew
Recent studies indicate that, near equilibrium condition could not be maintained for bulk viscous matter models during the accelerated expansion of the universe in the context of E…
