Joint Analysis of Constraints on f(R) Parametrization from Recent Cosmological Observations
Darshan Kumar, Praveen Kumar Dhankar, Saibal Ray +1
In this study, we present constraints on the parameters of three well-known gravity models, viz. (i) Hu-Sawicki, (ii) Starobinsky, and (iii) ArcTanh by using a joint analysi…

Cosmological model in the framework of gravity with quadratic equation of state parameter
Vinod Kumar Bhardwaj, Saibal Ray
In this study, we have explored a transitioning cosmological model of universe's expansion in gravity. The quadratic type of equation of state parameter in t…
