“…A lot of attempts have been made through DE models to investigate its existence as well as certain popular modified gravities. Numerous observations have also been carried out to measure cosmic acceleration from different factors [9,10].…”

In the framework of dynamical Chern–Simons theory of gravity, we study the recent cosmic expansion with acceleration of the universe. We take interacting scenario of dark energy and dark matter with three cutoffs like Granda–Oliveros, higher order derivative of Hubble parameter and generalized holographic dark energy model. In the flat Friedmann–Robertson–Walker universe, well-known cosmological parameters have been calculated. We study the perturbation of matter density growth, growth factor and growth index behavior for the underlying framework. The cosmological parameters like equation of state parameter, deceleration parameter, and stability of each model are discussed. The outcomes of these models represent the cosmic expansion of the universe with acceleration.

“…This late time accelerated expansion of the universe has been confirmed by high redshift supernovae experiments (Riess et al [7], Perlmutter et al [8], Bennett et al [9]). Also, observations such as cosmic background radiation [10,11] and large-scale structure [12] provide an indirect evidence for late time acceleration.…”

The present study deals with spatially homogeneous and totally anisotropic Bianchi type-VI 0 bulk viscous cosmological models in Lyra geometry. The Einstein's field equations have been solved exactly by taking the shear (r) in the model proportional to expansion scalar ðhÞ which leads to A = B n , where A and B are metric functions and n is a positive constant (n [ 1). We also adopt a condition fh ¼ L (constant) where f is the coefficient of bulk viscosity. It has been found that the displacement vector (b) is a decreasing function of time and it approaches to a small positive value at late time which is supported by recent observations. It is also found that the distance modulus curve of derived model matches with observations perfectly.
