Stability Analysis of Cosmological Perturbations in the Bumblebee Model: Parameter Constraints and Gravitational Waves
Xiao-Bin Lai, Yu-Qi Dong, Yu-Zhi Fan +1
We constrain the parameter space of the Bumblebee model in a cosmological background and then investigate the properties of gravitational waves within the constrained parameter spa…

Polarization modes of gravitational waves in general symmetric teleparallel gravity
Yu-Qi Dong, Xiao-Bin Lai, Yu-Zhi Fan +1
In this paper, we investigate the polarization modes of gravitational waves within the most general symmetric teleparallel gravity theory that allows for second-order field equatio…

New gravitational wave polarization modes in the torsionless spacetime
Yu-Qi Dong, Xiao-Bin Lai, Yu-Zhi Fan +1
In this study, we investigate the polarization properties of gravitational waves within a torsionless spacetime framework, as described by the Palatini formalism. Our analysis unco…
