The gravity and affine EoS: observational aspects
Romanshu Garg, G. P. Singh
In this paper, we investigate the cosmic expansion scenarios within the framework of gravity by using the affine equation of state (EoS) parameter. Specifically, we consid…
The gravity and affine EoS: Compatibility and observational constraints
Romanshu Garg, G. P. Singh, Ashutosh Singh
We study the cosmological implications of barotropic fluid satisfying affine equation of state (EoS) in the General relativity and gravity framework. We describe the impact…
Dynamical constraints on variable vacuum energy in Brans-Dicke theory
Khomesh R. Patle, G. P. Singh, Romanshu Garg
In this research work, we investigate the late-time accelerated expansion of the universe within the framework of Brans-Dicke theory by considering dynamical vacuum energy models w…
Cosmological Dynamics of Accelerating Model in Gravity with Special Forms of Deceleration Parameter
Shivank Pal, Romanshu Garg, Gyan Prakash Singh +1
In this paper, the dynamical behavior of the accelerated expansion of the universe is discussed within the framework of gravity, considering power law functional form of $ f…
Cosmological model with Gong-Zong Parametrization in gravity
Romanshu Garg, Tanmoy Chowdhury, G. P. Singh +1
We present the cosmic expansion scenarios in the gravity studied by using the dark energy equation of state (EoS) parameters. We proceed with the specific form of $f(R,…
Accelerated expansion of the universe model with parametrization of in theory of gravity
Khomesh R. Patle, G. P. Singh, Romanshu Garg
In this research work, we explore the late-time accelerated expansion of the universe within the framework of modified gravity, specifically theory, by considering two…
