Abstract The Nobel Prize winning confirmation in 1998 of the accelerated expansion of our
Universe put into sharp focus the need of a consistent theoretical model to explain the origin …

To find more deliberate f (R, T) cosmological solutions, we take our previous paper further by
studying some new aspects of the considered models via investigation of some new …

We study the dynamics of the field equations in a four-dimensional isotropic and
homogeneous spatially flat Friedmann-Lemaître-Robertson-Walker geometry in the context …

In a spatially flat Friedmann-Lemaître-Robertson-Walker universe, we investigate a unified
cosmic fluid scenario endowed with bulk viscosity in which the coefficient of the bulk …

We study in detail the phase space of a Friedmann-Robertson-Walker universe filled with
various cosmological fluids that may or may not interact. We use various expressions for the …

In this work, we study two scenarios of the Universe filled by a perfect fluid following the
traditional dark energy and a viscous fluid as dark matter. In this sense, we explore the most …

In this work we explore a new cosmological solution for an universe filled with one
dissipative fluid, described by a barotropic equation of state (EoS) p= ω ρ, in the framework …

In this paper, we explore an extension of the classical non-standard cosmological scenario
in which the new field, ϕ, which interacts with the radiation component in the early universe …

We investigate the phase-space structure of the quintom dark energy paradigm in the
framework of spatially flat and homogeneous universe. We have also included radiation and …

The article communicates an alternative route to suffice the late-time acceleration
considering a bulk viscous fluid with viscosity coefficient ζ= ζ 0+ ζ 1 H+ ζ 2 H 2, where ζ 0, ζ …
