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…
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…
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…
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…
Late-time dynamics of dark energy EoS in symmetric teleparallel gravity
Romanshu Garg, G. P. Singh, Ashutosh Singh
In the symmetric teleparallel gravity framework, we study the cosmic dynamics of the universe with dark energy equation of state (EoS) parameter having non-linear forms. The non-me…
