Anisotropic Bianchi Type-VIh Perfect Fluid Cosmological Models in a Modified Theory of Gravity

V. U. M. Rao, M. Vijaya Santhi, Y. Aditya


An anisotropic Bianchi type-VIh cosmological space-time with perfect fluid source in the frame work of f(R,T) modified theory of gravity proposed by Harko et al. [1] has been investigated for a special choice of f(R,T) =f1(R)+f2(T). To obtain a solution, it is assumed that scalar of expansion is proportional to shear scalar i.e. θ ∝ σ2, which leads to a relation between metric potentials. Some important properties of the universe including look-back time, distance modulus and luminosity distance versus redshift with their significances are discussed.
