Propagation and polarization of gravitational waves on curved spacetime backgrounds in Einstein-Ãther theory
Yu-Qi Dong, Shinji Mukohyama, Yu-Xiao Liu
We analyze the propagation and polarization properties of high-frequency gravitational waves in Einstein-Ãther theory on vorticity-free and slowly-varying backgrounds at both lead…
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…
Complexity equals anything for multi-horizon black holes
Hong-Yue Jiang, Yu-Xiao Liu
We investigate the ``complexity equals anything" proposal with codimension-one and codimension-zero gravitational observables for multi-horizon black holes, using the Bardeen-AdS c…
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…
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…
Gravitational-wave effects in the most general vector-tensor theory
Yu-Qi Dong, Xiao-Bin Lai, Yu-Qiang Liu +1
In this paper, we establish a model-independent framework based on the Isaacson picture to analyze the gravitational-wave effects in the most general vector-tensor theory that yiel…
