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-subclass of Einstein-aether theory
Chikun Ding, Yuebing Zhou, Yu Shi +1
We obtain an exact -dimensional aether charged black hole solution and gravitational wave polarizations in the M-subclass of the Einstein-aether theory with Lorentz invariance v…
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…
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…
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…
Testing the cosmic distance duality relation using Type Ia supernovae and radio quasars through model-independent methods
Fan Yang, Xiangyun Fu, Bing Xu +3
In this work, we perform a cosmological-model-independent test on the cosmic distance duality relation (CDDR) by comparing the angular diameter distance (ADD) obtained from the com…
Testing the cosmic distance duality relation with Type Ia supernova and transverse BAO measurements
Min Wang, Xiangyun Fu, Bing Xu +3
In this work, we test the cosmic distance duality relation (CDDR) by comparing the angular diameter distance (ADD) derived from the transverse Baryon Acoustic Oscillations (BAO) da…
Refinements and corrections to the deflection angle of light in Kerr-de Sitter spacetime
Yang Huang, Xiangyun Fu
The deflection angle of equatorial light (the light in the equatorial plane) in Kerr-de Sitter (KdS) spacetime was previously calculated by Sultana [\href{https://journals.aps.org/…
