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…
-dimensional aether charged black hole and aether waves in M-subset of Einstein-aether theory
Chikun Ding, Yuebing Zhou, Yu Shi +1
We study the black hole solution and gravitational wave polarizations in a M-subset of the Einstein-aether theory with Lorentz invariance violated by an unit norm vector field -- t…
Impact of Interacting Dark Energy on the Growth of Matter Density Perturbations: Observational Constraints from DESI and Multi-Probe Data
Fan Yang, Rongrong Zhai, Xiangyun Fu +4
We investigate the impact of a non-gravitational dark sector interaction on the growth of matter density perturbations within both the interacting CDM and the dynamical Chevalli…
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…
Testing the cosmic distance duality relation using Type Ia supernovae and BAO observations
Fan Yang, Xiangyun Fu, Bing Xu +3
In this work, we propose to utilize the observed ratio of spherically-averaged distance to the sound horizon scale from Baryon Acoustic Oscillation (BAO) data to test the cosmic di…
