Topology of light rings for extremal and non-extremal Kerr-Newman Taub-NUT black holes without symmetry
Shan-Ping Wu, Shao-Wen Wei
Understanding the light ring, one kind fundamental orbit, shall provide us with novel insight into the astronomical phenomena, such as the ringdown of binary merger and shadow of b…
