Quasinormal modes of scalar and Maxwell field perturbations coupled to the Einstein tensor in generalized Nariai spacetimes
Xin Qin, Xiongying Qiao, Qiyuan Pan +3
We investigate the quasinormal modes of scalar and Maxwell field perturbations coupled to the Einstein tensor in generalized Nariai spacetimes. Our results show that, for both type…

The influence of cosmological constant on light deflection in rotating spacetimes via the generalized Gibbons-Werner method
Yang Huang, Xiangyun Fu, Zhenyan Lu +1
Recently, we proposed a generalized Gibbons-Werner (GW) method for analyzing particle trajectories in rotating spacetimes, regardless of their asymptotic behavior [Huang \textit{et…
