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 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 …

We conduct a Bayesian analysis of recent observational datasets, specifically the Cosmic
Chronometers (CC) dataset and Pantheon samples, to investigate the evolution of the EoS …

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 …

We investigate observational constraints on cosmological parameters combining 15
measurements of the transversal BAO scale (obtained free of any fiducial cosmology) with …

In this study, we examined the late-time cosmic expansion of the universe within the
framework of f (Q, L m) gravity, where Q denotes the non-metricity and L m represents the …

A study on the effects of implementing the Granda–Oliveros infrared cutoff in the recently
introduced Barrow holographic dark energy model is presented, and its cosmological …

The cosmic curvature density parameter has been constrained in the present work
independent of any background cosmological model. The reconstruction is undertaken …

Machine learning (ML) algorithms have revolutionized the way we interpret data in
astronomy, particle physics, biology, and even economics, since they can remove biases …

This article introduces three novel parametrizations of the deceleration parameter (DP) to
explore the cosmological scenario. The newly introduced parametric forms of the DP are …
