Scalar field in Bianchi type-I cosmology with Lyra's geometry
Evgeny Petuhov, Bijan Saha
In this study, we examine the role of a scalar field in the evolution of the Universe within the framework of a Bianchi type-I cosmological model with Lyra's geometry. Previous res…
Testing an anisotropic spinor field--based Modified Chaplygin Gas model in Kantowski--Sachs spacetime with observational constraints
Mahendra Goray, Bijan Saha
We investigate a cosmological model based on a massless nonlinear spinor field coupled to a Modified Chaplygin Gas (MCG) in the Kantowski--Sachs spacetime, aiming to probe anisotro…
Nonlinear spinor field with Lyras geometry: Bianchi type-VI space-time
Bijan Saha
In the context of a Bianchi type-VI space-time characterized by Lyras geometry, we investigate the influence of a nonlinear spinor field on the evolution of the Universe. Our previ…
Observational Constraints on a Spinor Field Generalized Chaplygin Gas Model in a Spherically Symmetric FLRW Spacetime
Mahendra Goray, Bijan Saha
Despite the remarkable success of the standard LambdaCDM model in describing the evolution of the universe, several unresolved issues remain, such as the true nature of dark energy…
Constraining parameters of spinor field dark energy: An alternative to CDM model under the spherically symmetric FLRW space-time
Bijan Saha, Mahendra Goray
This study constrains the cosmological parameters within the scope of a spherically symmetric FLRW cosmological model, the role of a nonlinear spinor field in the universe's evolut…
