Cosmic reverberations on a constrained -model of the Universe
Akanksha Singh, Shaily, J. K. Singh +1
In this paper, we construct an isotropic cosmological model in the theory of gravity in the frame of a flat FLRW spacetime being the non-metricity tensor and $ T…
Evolution of the universe with quintessence model in Rastall gravity
J. K. Singh, Akanksha Singh, Shaily +2
We investigate the universe's evolution within the framework of Rastall gravity, which is an extension of the standard CDM model. Utilizing a linear parametrization of the Equa…
The consequence of higher-order curvature-based constraints on gravity
J. K. Singh, Shaily, Akanksha Singh +2
In this investigation, we perform an observational statistical analysis in the theory of gravity. The proposed theoretical model is based on the Ricci scalar's non-li…
Stability analysis of a dark energy model in Rastall gravity
Shaily, Akanksha Singh, J. K. Singh +2
We study a cosmological model in Rastall's theory of gravity in the framework of the flat FLRW metric. We formulate the value of the Hubble parameter, which contains two model para…
