Universe described by dark energy in the form of wet dark fluid (WDF) in higher-dimensional space-time

Abstract

The new class of higher-dimensional cosmological model of the early universe filled with dark energy in the form of wet dark fluid, within the framework of the f (R, T) theory of gravity (Harko et al., Phys. Rev. D 84, 024020 (2011)) is considered. A new equation of state for the dark- energy component of the universe is used. It is modeled on the equation of state $ p=\omega (\rho-\rho^{\ast})$ , which can be describing a liquid, for example, water. A cosmological model with an appropriate choice of the function f (T) is constructed. The physical behavior of the model is studied. The well-known astrophysical phenomena, namely the Hubble parameter, lookback time, proper distance, luminosity distance, distance modulus, angular diameter, jerk parameter and cosmic snap with redshift and statefinder parameters are discussed.
