Effective equation of state in modified gravity and observational constraints
Simran Arora, Xin-he Meng, S. K. J. Pacif +1
In this article, the bulk viscosity is introduced in a modified gravity model. The gravitational action has a general form, where and are the curvature scalar an…
gravity models with observational constraints
Simran Arora, S. K. J. Pacif, Snehasish Bhattacharjee +1
The paper presents late time cosmology in gravity where the dark energy is purely geometric in nature. We start by employing a well motivated gravity model, $f(Q,…
Dark energy models from a parametrization of : A comprehensive analysis and observational constraints
S. K. J. Pacif
The presented paper is a comprehensive analysis of two dark energy (DE) cosmological models wherein exact solutions of the Einstein field equations (EFEs) are obtained in a model-i…
Accelerating Universe in Hybrid and Logarithmic Teleparallel Gravity
Sanjay Mandal, Snehasish Bhattacharjee, S. K. J. Pacif +1
Teleparallel gravity is a modified theory of gravity for which the Ricci scalar of the underlying geometry in the action is replaced by an arbitrary functional form of torsion…
