Shao-Wen Wei, Bao-Min Gu, Yong-Qiang Wang, Yu-Xiao Liu

摘要:

本文讨论了极端Kerr-Newman黑洞背景下从近视界区到远处观测点的零测地线。特别地,利用匹配渐近展开法,我们以代数方程的形式解析地求解了超辐射界附近的零测地线。对于光子轨迹被限制在赤道平面内的情况,得到了方位角和时间的变化。

英文摘要:

In this paper, we deal with the null geodesics extending from the near-horizon region out to a distant observatory in an extremal Kerr-Newman black hole background. In particular, using the matched asymptotic expansion method, we analytically solve the null geodesics near the superradiant bound in the form of algebraic equations. For the case that the photon trajectories are limited in the equatorial plane, the shifts in the azimuthal angle and time are obtained.
