Observational Constraints and Cosmographic Analysis of Gravity and Cosmology
Harshna Balhara, J. K. Singh, Shaily +1
We perform observational confrontation and cosmographic analysis of gravity and cosmology. This higher-order torsional gravity is based on both the torsion scalar, as we…
A model of dark matter dark energy interaction with some cosmic consequences
J. K. Singh, Ritika Nagpal
In this study, we will look at an interacting dark energy model. In the framework of Friedmann-Robertson-Walker (FRW) space-time, we have made the hypothesis of an interacting sche…
The Reconstruction of Constant Jerk Parameter with Gravity in Bianchi-I spacetime
Anirudh Pradhan, Gopikant Goswami, Syamala Krishnannair
We have developed a Bianchi I cosmological model of the universe in gravity theory which fit good with the present day scenario of accelerating universe. The model display…
Reconstruction of an Observationally Constrained gravity model
Anirudh Pradhan, Gopikant Goswami, Aroonkumar Beesham
In this paper, an attempt is made to construct a Friedmann-Lemaitre-Robertson-Walker model in gravity with a perfect fluid that yields acceleration at late times. We take…
A non-singular bouncing cosmology in gravity
J. K. Singh, Shaily, Akanksha Singh +2
We investigate a bounce realization in the framework of higher order curvature in modified theory of gravity. We perform a detailed analysis of the cosmological paramete…
New parametrization of the dark-energy equation of state with a single parameter
J. K. Singh, Preeti Singh, Emmanuel N. Saridakis +2
We propose a novel dark-energy equation-of-state parametrization, with a single parameter that quantifies the deviation from CDM cosmology. We first confront the scenario wi…
