چکیده

In this paper, we have investigated a bulk viscous anisotropic Universe and constrained its model parameters with recent $H(z)$ Pantheon compilation data. Using cosmic chronometric technique, estimate the present value of Hubble's constant as $H_{0} = 69.39 \pm 1.54~km~s^{-1}Mpc^{-1}$, $70.016 1.65~km~s^{-1}Mpc^{-1}$ $69.36 1.42~km~s^{-1}Mpc^{-1}$ by bounding our derived data, joint data respectively. The age is specified $t_0= 0.9796H_0^{-1}\sim 13.79$ Gyrs. favours transitioning transition red-shift $z_{t} 0.73$. We reconstructed jerk parameter using observational sets. From analysis parameter, it observed that, shows marginal departure from concordance $\Lambda$CDM model.

Anisotropic Bianchi Type-III Bulk Viscous Fluid Universe in Lyra Geometry

An anisotropic Bianchi type-III cosmological model is investigated in the presence of a bulk viscous fluid within the framework of Lyra geometry with time-dependent displacement vector. It is shown that the field equations are solvable for any arbitrary function of a scale factor. To get the deterministic model of the universe, we have assumed that (i) a simple power-law form of a scale factor ...

Magnetized Bianchi Type V I 0 Bulk Viscous Barotropic Massive String Universe with Decaying Vacuum Energy Density Λ

Bianchi type V I0 bulk viscous massive string cosmological models using the technique given by Letelier (1983) with magnetic field are investigated. To get the deterministic models, we assume that the expansion (θ) in the model is proportional to the shear (σ) and also the fluid obeys the barotropic equation of state. The viscosity coefficient of bulk viscous fluid is assumed to be a power func...

Some Bianchi Type I Cosmological Models of the Universe for Viscous Fluid Distribution in Lyra Geometry

Some Bianchi type I cosmological models of the universe with time dependent gauge function β for viscous fluid distribution within the framework of Lyra geometry are investigated in which the expansion is considered only in two dimensions i.e. one of the Hubble parameter (H1 = Ȧ A) is zero. To get the deterministic solutions of Einstein’s modified field equations, the viscosity coefficient of b...

Tilted Bianchi Type V Bulk Viscous Cosmological Models with Varying Λ-term

Conformally flat tilted Bianchi type V cosmological models in presence of a bulk viscous fluid and heat flow are investigated. The coefficient of bulk viscosity is assumed to be a power function of mass density. The cosmological constant is found to be a decreasing function of time, which is supported by results from recent type Ia supernovae observations. Some physical and geometric aspects of...

Bianchi Type V Bulk Viscous Cosmological Models with Time Dependent Λ-Term

Spatially homogeneous and anisotropic Bianchi type V space-time with bulk viscous fluid source and time-dependent cosmological term are considered. Cosmological models have been obtained by assuming a variation law for the Hubble parameter which yields a constant value of deceleration parameter. Physical and kinematical parameters of the models are discussed. The models are found to be compatib...
