Geometry of the Universe Described by Wet Dark Fluid in f(R, T) Theory of Gravity

Abstract

The Bianchi type-III cosmological model in $$f(R,T)$$ gravity is investigated with the equation of state for wet dark fluid, i.e., $$P_{\text{WDF}} = \omega (P_{\text{WDF}} - \rho^{*} )$$ . Using volumetric and power-law expansion, we obtained the exact solution of the field equations. The various astrophysical phenomena, namely, the look-back time, proper distance, luminosity distance, angular diameter, jerk parameter, and cosmic snap with red shift and state-finder parameters, are also discussed.
