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…
Near-horizon polarized images of a rotating hairy Horndeski black hole
Chengjia Chen, Qiyuan Pan, Jiliang Jing
Recently, Hou \emph{et al.} [Astrophys. J. Lett. \textbf{988}, L51 (2025)] revealed that the Electric Vector Position Angle (EVPA) of polarization vectors in the near-horizon image…
Probing Kalb-Ramond field with extreme mass ratio inspirals
Zhong-Wu Xia, Huajie Gong, Qiyuan Pan +1
The extreme-mass-ratio inspirals (EMRIs) are emerging as precision laboratories for testing the gravity beyond general relativity. In this work, we investigate the Lorentz symmetry…
Stationary scalar clouds around a rotating BTZ-like black hole in the Einstein-bumblebee gravity
Fangli Quan, Fengjiao Li, Qiyuan Pan +2
We have studied stationary clouds of massive scalar fields around a rotating BTZ-like black hole in the Einstein-bumblebee gravity, by imposing the Robin type boundary conditions a…
Precessions of spherical orbits in the rotating Melvin black hole spacetime and its constraints from the jet of M87*
Chengjia Chen, Qiyuan Pan, Jiliang Jing
We investigate precessions of spherical orbits of timelike particles in the background of a rotating black hole immersed in the Melvin magnetic field, and probe effects of the magn…
Gravitational waves from extreme mass ratio inspirals in Kerr-MOG spacetimes
Xiongying Qiao, Zhong-Wu Xia, Qiyuan Pan +3
This work elaborates on a detailed analysis of the novel characteristics of gravitational waves (GWs) generated by extreme mass ratio inspirals (EMRIs) within the framework of modi…
