Novel extended inner shadow in images of Johannsen-Psaltis black holes with thin accretion disks
Xinyu Wang, Xiaobao Wang, Xin-Yang Wang +1
The Johannsen-Psaltis (JP) metric is constructed by introducing deviation parameters into the Kerr metric. The presence of these deviation parameters provides additional degrees of…

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 t…
