In this paper, we focus on the parametrization of the effective equation of state (EoS)
parameter within the framework of f (Q) symmetric teleparallel gravity. Here, the gravitational …

We measure cosmological parameters using the three-dimensional power spectrum P (k)
from over 200 000 galaxies in the Sloan Digital Sky Survey (SDSS) in combination with …

In this article, we have investigated the role of bulk viscosity to study the accelerated
expansion of the universe in the framework of modified f (Q) gravity. The gravitational action …

We propose a logarithmic parametrization form of energy density for the scalar field dark
energy in the framework of the standard theory of gravity, which supports the necessary …

The dynamics of the Universe is analyzed using an exponential function for the dark energy
equation of state, known as Gong-Zhang parameterization. The phase space of the free …

In this paper, we examine the accelerated expansion of the Universe at late‐time in the
framework of f (Q) f(Q) gravity theory in which the non‐metricity scalar Q describes the …

In theoretical physics, the fundamental nature and evolution mechanism of dark energy is
still an open question. In General Relativity Theory, the simplest explanation for dark energy …

This paper is devoted to investigate the anisotropic locally rotationally symmetric (LRS)
Bianchi type-I space–time in the context of the recently proposed f (Q) gravity in which Q is …

In this paper, we investigate a cosmological model based on viscous f (R, T) gravity as a
potential alternative to dark energy. This model incorporates bulk viscosity and is analyzed …

On the basis of homogeneous and isotropic Friedmann-Lemaitre-Robertson-Walker (FLRW)
geometry, solutions to the issues of cosmic acceleration and dark energy are being put forth …
