Polarized image of an equatorial emitting ring around a Konoplya-Zhidenko rotating non-Kerr black hole

Xin Qin, Fen Long, Songbai Chen +1

We investigate the polarized images of an equatorial emitting ring around a Konoplya-Zhidenko rotating non-Kerr black hole, which introduces an additional deformation parameter. Th…

The images of Brans-Dicke-Kerr type naked singularities

Fen Long, Weike Deng, Xin Qin +2

We have studied the images of the Brans-Dicke-Kerr spacetime with a dimensionless Brans-Dicke parameter , which belongs to axisymmetric rotating solutions in the Brans-Dicke th…

Dynamic shadow of a black hole with a self-interacting massive complex scalar hair

Mingzhi Wang, Cheng-Yong Zhang, Songbai Chen +1

We investigate the dynamic shadows of a black hole with a self-interacting massive complex scalar hair. The complex scalar field ψevolves with time t, and its magnitude on the app…

Gravitational waves from equatorially eccentric extreme mass ratio inspirals around swirling Kerr black holes

Yuhang Gu, Songbai Chen, Jiliang Jing

The swirling-Kerr black hole is a novel solution of vacuum general relativity and has an extra swirling parameter characterizing the rotation of spacetime background. We have studi…

Gravitational waveforms from periodic orbits around a charged black hole with scalar hair

Weike Deng, Sheng Long, Qin Tan +1

We investigate geodesic motion and gravitational-wave signatures of charged black holes with scalar hair. Using the effective potential approach, we analyze marginally bound orbits…
