Correspondence of eikonal quasinormal modes and unstable fundamental photon orbits for Kerr-Newman black hole
Peng-Cheng Li, Tsai-Chen Lee, Minyong Guo +1
In this work, we study the relation of the eikonal quasinormal modes (EQNMs) and the unstable fundamental photon orbits (UFPOs) in the Kerr-Newman spacetime. We find that in the ei…
Revisiting the shadow of braneworld black holes
Yehui Hou, Minyong Guo, Bin Chen
We revisit the shadows of rotating braneworld black holes in the Randall-Sundrum type II model, by considering not only the metric in the near region of the black hole but also the…
QED Effect on Black Hole Shadow
Zezhou Hu, Zhen Zhong, Peng-Cheng Li +2
In this work, taking the QED effect into account, we investigate the shadows of the static black hole with magnetic monopoles and neutral black holes in magnetic fields through the…
Shadow of a Spinning Black Hole in an Expanding Universe
Peng-Cheng Li, Minyong Guo, Bin Chen
We study the influence of the cosmic expansion on the size of the shadow of a spinning black hole observed by a comoving observer. We first consider that the expansion is driven by…
Photon Emission Near Myers-Perry Black Holes in the Large Dimension Limit
Minyong Guo, Peng-Cheng Li, Bin Chen
We study the null geodesics extending from the near-horizon region out to the far region in the background of the Schwarzschild and the singly-spinning Myers-Perry black holes in t…
