Cosmological Perturbations and Observational Constraints on Spinor Field Quintessence Dark Energy

Mahendra Goray

We investigate the linear perturbation cosmology of a spinor-field realization of quintessence dark energy by implementing the model in the Einstein--Boltzmann solver \texttt{CLASS…

Constraining parameters of spinor field dark energy: An alternative to $Λ$ 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…
