Domain walls and quark matter in Bianchi type-V universe with observational constraints in F(R,T) gravity

Abstract

In this study, we investigate the Bianchi type-V cosmological models with quark matter (QM) distribution and domain walls with observational constraints in [Formula: see text] theory of gravity (Harko et al. in Phys. Rev. D 84 (2011) 024020), for a specific choice of the function [Formula: see text] (where [Formula: see text] is Ricci scalar and [Formula: see text] is the trace of the energy–momentum tensor). We have used model-independent methods and hyperbolic expansion scale factors to achieve the deterministic solution of the modified Einstein field equations and these are also tested observationally. The behaviors of QM and domain walls give an idea of accelerated expansion of the Universe which agrees with recent observations of Type Ia Supernovae. We also discuss the physical implications of the derived models.
