Phase space analysis of Bianchi III Universe with gravity theory
Pranjal Sarmah, Umananda Dev Goswami
The Bianchi type III (BIII) metric is a useful geometry to study cosmic anisotropies. It includes an extra exponential term multiplied by a directional scale factor and recasts the…
Ultra-high energy cosmic rays with UFA-15 source model in Bumblebee gravity theory
Swaraj Pratim Sarmah. Pranjal Sarmah, Umananda Dev Goswami
We explore the effects of Bumblebee gravity on the propagation of ultra-high energy cosmic rays (UHECRs) using astrophysical sources modelled in the Unger-Farrar-Anchordoqui (UFA)…
Observational constraints on cosmological parameters in the Bianchi type III Universe with f(R,T) gravity theory
Pranjal Sarmah, Umananda Dev Goswami
Bianchi type III (BIII) metric is an interesting anisotropic model for studying cosmic anisotropy as it has an additional exponential term multiplied to a directional scale factor.…
Anisotropic cosmology in Bumblebee gravity theory
Pranjal Sarmah, Umananda Dev Goswami
The Bumblebee vector model of spontaneous Lorentz symmetry breaking (LSB) in Bianchi type I (BI) Universe to observe its effect on cosmological evolution is an interesting aspect o…
