Imaging and Polarimetric Signatures of Konoplya-Zhidenko Black Holes with Various Thick Disk
Xinyu Wang, Yukang Wang, Xiao-Xiong Zeng
We investigate the imaging properties of spherically symmetric Konoplya-Zhidenko (KZ) black holes surrounded by geometrically thick accretion flows, adopting a phenomenological rad…

Imaging and polarization patterns of various thick disks around Kerr-MOG black holes
Xinyu Wang, Huan Ye, Xiao-Xiong Zeng
We investigate the imaging and polarization properties of Kerr-MOG black holes surrounded by geometrically thick accretion flows. The MOG parameter introduces deviations from…

Revisiting the shadow of Johannsen-Psaltis black holes
Xinyu Wang, Zhixing Zhao, Xiao-Xiong Zeng +1
The Johannsen-Psaltis (JP) metric provides a robust framework for testing the no-hair theorem of astrophysical black holes due to the regular spacetime configuration around JP blac…
