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

摘要

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*), 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.
