Bianchi Type V String Cosmological Models with Late Time Acceleration

Abstract

In the current work, the possibility of late time acceleration with string fluid as the matter source in Bianchi type V is considered. By assuming the functional form of the Hubble parameter, we explore cosmological hypotheses. The resulting models begin in the early stages of evolution as highly anisotropic and gradually move closer to an isotropic universe. Additionally, we have calculated cosmological parameters such as the string tension density, the particle density, the average Hubble parameter, shear scalar, scalar expansion and the energy density of the string. Physical and geometrical behavior of the universe has been discussed in detail.
