摘要

最近在圈量子引力中提出了量子奥本海默-斯奈德引力坍缩模型，提供了量子校正的史瓦西时空作为坍缩尘埃球的外部。本文研究了该模型中量子引力对黑洞阴影的影响，并通过计算准正态模分析了量子修正后黑洞的稳定性。结果表明，量子修正总是缩小阴影的半径，并且量子修正的黑洞在标量和矢量扰动下是稳定的。

Shadow and stability of quantum-corrected black holes

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.
