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…

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…

A generalized CDM model with parameterized Hubble parameter in particle creation, viscous and model framework
G. P. Singh, Romanshu Garg, Ashutosh Singh
In this study, we construct a theoretical framework based on the generalized Hubble parameter form which may arise within the particle creation, viscous and gravity theory.…
