论文摘要
最近，已经提出了Quantum oppenheimer-snyder重力塌陷模型，以循环量子重力为量子，从而作为量子校正的Schwarzschild spaceTimes作为倒塌的灰尘球的外部。在本文中，研究了该模型中对黑洞阴影的量子重力影响，并且还通过计算准标准模式来分析量子校正的黑洞的稳定性。事实证明，量子校正始终会缩小阴影的半径，而经量子校正的黑洞对标量和矢量扰动稳定。
Recently the quantum Oppenheimer-Snyder gravitational collapse model has been proposed in loop quantum gravity, providing quantum-corrected Schwarzschild spacetimes as the exterior of the collapsing dust ball. In this paper, the quantum gravity effects on the black hole shadows in this model are studied, and the stability of the quantum-corrected black holes is also analyzed by calculating the quasinormal modes. It turns out that the quantum correction always shrinks the radius of shadows, and the quantum-corrected black holes are stable against the scalar and vector perturbations.
