规则黑洞在量子修正引力下的辐射和喷流特征

Radiative and Jet Signatures of Regular Black Holes in Quantum-Corrected Gravity

Chirantana Bhattacharjee, Subhadip Sau, Avijit Mukherjee

摘要:

我们研究规则旋转的黑洞的渐近安全的引力预测,其中牛顿常数随能量标度变化,并修改了近视界几何。这些解决方案保持渐近平坦,避免中心奇点,而不同于经典的克尔时空中的强场区域。我们计算了薄吸积盘的辐射效率和Blandford Znajek机制下的喷注功率,它们都依赖于模型的形变参数。的预测相比,观测估计的六个恒星质量的黑洞。对于低或中等自旋的系统,模型再现了报告的不确定性内的数据,而快速旋转的源,如GRS 1915 105目前的紧张局势,并指出一个有限的变形范围或需要额外的物理。结果表明,仅限于强引力区的量子修正仍然可以在高能天体物理过程中留下可检测的印记。因此,基于辐射和喷流的诊断提供了一种很有前途的方法来测试视界附近的几何形状,并探索观测中可能的量子引力特征。

英文摘要:

We investigate regular rotating black holes predicted by asymptotically safe gravity, where the Newton constant varies with energy scale and modifies the near horizon geometry. These solutions remain asymptotically flat and avoid central singularities while differing from the classical Kerr spacetime in the strong field region. We compute the radiative efficiency of thin accretion disks and the jet power from the Blandford Znajek mechanism, both of which depend on the deformation parameter of the model. The predictions are compared with observational estimates for six stellar mass black holes. For systems with low or moderate spin the model reproduces the data within reported uncertainties, while rapidly spinning sources such as GRS 1915 105 present tensions and point to a restricted deformation range or the need for additional physics. The results show that quantum corrections confined to the strong gravity regime can still leave detectable imprints on high energy astrophysical processes. Radiative and jet based diagnostics therefore provide a promising method to test the geometry near the horizon and to explore possible signatures of quantum gravity in observations.
