Late-time viscous cosmology in f(R, T) gravity

The article communicates an alternative route to suffice the late-time acceleration considering a bulk viscous fluid with viscosity coefficient $\zeta =\zeta _{0}+ \zeta _{1} H + _{2} H^{2}$, where _{0}, _{1}, _{2}$ are constants in framework of $f(R,T)$ modified gravity. We presume functional form be $f=R+2\alpha T$ $\alpha$ is constant. then solve field equations for Hubble Parameter and study cosmological dynamics kinematic variables such as deceleration, jerk, snap lerk parameters function cosmic time. observe deceleration parameter highly sensitive undergoes signature flipping at around $t\sim 10$ Gyrs $\alpha=-0.179$ which favored by observations. EoS our model assumes values close $-1$ $t_{0}=13.7$Gyrs remarkable agreement latest Planck measurements. Next, we evolution energy conditions find that violate Strong Energy Condition order explain acceleration. To understand nature dark mimicked baryonic fluid, perform some geometrical diagnostics like $\{r,s\}$ $\{r,q\}$ plane. found mimic Chaplygin gas type early times while Quintessence distant future. Finally, violation continuity equation show present epoch, energy-momentum must violate.
