Observationally Constrained Cosmological model in Gravity with parameterization
Vinod Kumar Bhardwaj, Maxim Khlopov, Maxim Krasnov +1
In the present work, we explore an observationally constrained cosmological model in the framework of gravity, where denotes the non-metricity scalar and…
Cosmological Implications of the Gong-Zhang Parameterization in Rastall Gravity: A Deep Learning and Observational Study
Vinod Kumar Bhardwaj, Anil Kumar Yadav, Manish Kalra +2
In this study, we have explored the cosmological dynamics of an isotropic, homogeneous universe in Rastall gravity. For this purpose, we use the parameterization of the EoS paramet…
Transitioning late-time cosmology with the Hubble parameterization
Vinod Kumar Bhardwaj, Saibal Ray, Kazuharu Bamba +1
We investigate a late-time cosmological model for a homogeneous and isotropic space-time in the Rastall theory. We explore the observational constraints on the Hubble parameter by…
Anisotropic cosmology using observational datasets: exploring via machine learning approaches
Vinod Kumar Bhardwaj, Manish Kalra, Priyanka Garg +1
In the current study, we present the observational data constraints on the parameters space for an anisotropic cosmological model of Bianchi I type spacetime in general relativity…
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…
