Reconstruction of a dark energy model for the Dirac-Born-Infeld scalar field with the Hubble and DESI data via Gaussian process
Sayantan Ghosh, Gaurav N. Gadbail, P. K. Sahoo +1
In this study, we reconstruct the dark energy (DE) as a Dirac-Born-Infeld (DBI) scalar field from the Hubble dataset (32 CC + 26 BAO) and the DESI dataset using the Gaussian proces…
Qualitative Analysis of Cosmological Models Using Dynamical System Perspective
Sayantan Ghosh
This thesis investigates theoretical and observational aspects of cosmic acceleration, focusing on dark energy models and modified gravity frameworks. The goal is to analyse their…
Charged gravastar model in noncommutative geometry under gravity
Debasmita Mohanty, Sayantan Ghosh, P. K. Sahoo
In this article, we study the properties of charged gravastars in torsion-based gravity in the presence of noncommutative geometry. We have taken the interior from…
Study of charged gravastar model in gravity
Debasmita Mohanty, Sayantan Ghosh, P. K. Sahoo
In recent days gravastar has been a very lucrative alternative to black holes, as it does not suffer from the singularity problem as well and it is based on sound physical grounds.…
Dynamical system analysis of Dirac-Born-Infeld scalar field cosmology in coincident gravity
Sayantan Ghosh, Raja Solanki, P. K. Sahoo
In this article, we offer the dynamical system analysis of the DBI (Dirac-Born-Infeld) scalar field in a modified gravity context. We have taken a polynomial form of modifie…
Dynamical system analysis of scalar field cosmology in coincident gravity
Sayantan Ghosh, Raja Solanki, P. K. Sahoo
In this article, we investigate scalar field cosmology in the coincident gravity formalism. We calculate the motion equations of gravity under the flat Friedmann-Lema…
