Spatially homogeneous and anisotropic Bianchi type-I space-time with perfect fluid is considered within the framework of f(R, T) theory of gravity. We find the exact solutions of the field equations by assuming the time-dependent function of deceleration parameter of second degree. We observed an anisotropic Universe at an early epoch, which becomes isotropic at a late epoch. The transition phase of deceleration to acceleration is also established in this developed model. We discuss the slope of Om(z) diagnostic tool. It is found that the slope is negative at the beginning of the Universe and approaches to constant value at late epoch which implies that Universe will be dominated by dark energy (w = - 1) at late epoch. To check the consistency of the cosmological parameters with observations, we also examine the energy conditions of the models. [ABSTRACT FROM AUTHOR] |
