论文摘要
通过弹跳参数校正的reissner-nordström时空，研究了弱场极限，准光谱和灰体因子的重力镜头。使用高斯河网定理，我们分析了弹跳校正对弱重力偏转角的影响，并发现偏转角的差异可以通过Reissner-NordströmSpaceTime中的弹跳校正来抑制。我们还注意到，弹跳校正在偏转角度起着与摩尔斯电位相同的作用。此外，我们以自旋依赖性的雷格轮毂电势得出扰动方程，并讨论了准光谱稳定性。我们观察到无质量标量和电磁场扰动的准光谱均降低。我们进一步研究了由regge-wheeler电位散布的颗粒的传播概率，并揭示了引入Reissner-Nordström时空引入的弹跳校正增加了扰动场的灰色因子。
Gravitational lensing in the weak field limit, quasinormal spectra, and gray-body factors are investigated in the Reissner-Nordström spacetime corrected by bounce parameters. Using the Gauss-Bonnet theorem, we analyze the effects of bounce corrections to the weak gravitational deflection angle and find that the divergence of the deflection angle can be suppressed by a bounce correction in the Reissner-Nordström spacetime. We also notice that the bounce correction plays the same role as the Morse potential in the deflection angle. Moreover, we derive the perturbation equations with the spin-dependent Regge-Wheeler potential and discuss the quasinormal spectral stability. We observe that the quasinormal spectra decrease for both the massless scalar and electromagnetic field perturbations. We further study the transmission probability of particles scattered by the Regge-Wheeler potential and reveal that the bounce correction introduced into the Reissner-Nordström spacetime increases the gray-body factors of perturbation fields.
