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…

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…
