旋转黑洞的量子引力跨普朗克辐射

Quantum-gravitational trans-Planckian radiation by a rotating black hole

A. J. Nurmagambetov, I. Y. Park

摘要:

我们最近研究了一个量子修正的含时黑洞的能量行为。所分析的系统是量子校正的克尔解,其随着时间依赖性逐渐消失而稳定下来。在事件视界附近的trans-Planckian能量标度的结果,我们提出trans-Planckian辐射是活动星系核发光机制中缺失的环节。本工作的主要目标是通过分析量子动量密度来研究辐射的标度和结构。我们再次观察到一种反普朗克行为。此外,动量密度显示的结构表明赤道附近的盘状配置和来自两极的准直流出物质。双极外流(盘状结构)应该是活动星系核喷流(吸积盘)基本机制的重要组成部分。

英文摘要:

We recently studied the energy behavior of a quantum-corrected time-dependent black hole. The system analyzed was a quantum-corrected Kerr solution that settles down to a stationary configuration as the time dependence fades out. A trans-Planckian energy scaling in the vicinity of the event horizon resulted, and we proposed the trans-Planckian radiation to be the missing link in the glowing mechanism of active galactic nuclei. The main goal of the present work is to examine the scaling and structure of the radiation by analyzing the quantum momentum density. We again observe a trans-Planckian behavior. Furthermore, the momentum density displays structures that are indicative of a disk-like configuration near the equator and a collimated outflow of matter from the poles. The bipolar outflow (disk-like structure) should be an essential part of the underlying mechanism for jets (accretion disks) of active galactic nuclei.
