Two-Fluid Bianchi Type Cosmological model with Variable Deceleration Parameter in f (R, T) gravity

Abstract

In the present paper, we construct Bianchi-type cosmological model filled with perfect fluid and dark energy (DE) in theory of gravitation. To obtain the determinate solution of the field equations, the deceleration parameter (q) is assumed to be a function of cosmic time. The proposed work introduces a transitional model that shows the transition from decelerating to accelerating. It is observed that our model reassembles with model. We have also examined the features with cosmic redshift z which are found very close to recent observational data. Additionally, the geometric and physical properties of the cosmological model are discussed.
