论文摘要
在最近对螺母电荷的黑洞的研究中，我们研究了针对Kerr-Taub-nut黑洞的弱宇宙审查猜想的有效性，分别具有测试量的大规模标量场和一个测试粒子。对于标量场散射Gedanken实验，我们考虑了无限的时间间隔过程。结果表明，极端和近乎超级的Kerr-taub-nut黑洞都不能过度旋转。对于测试粒子思想实验，研究表明，极端的Kerr-taub-nut黑洞不能过度旋转。虽然近超级Kerr-taub-nut黑洞可以过度旋转。通过比较两种方法，结果表明越过黑洞地平线的颗粒的时间间隔对于考虑弱宇宙审查的猜想可能很重要。
Motivated by the recent researches of black holes with NUT charge, we investigate the validity of the weak cosmic censorship conjecture for Kerr-Taub-NUT black hole with a test massive scalar field and a test particle, respectively. For the scalar field scattering gedanken experiment, we consider an infinitesimal time interval process. The result shows that both extremal and near-extremal Kerr-Taub-NUT black holes cannot be over-spun. For the test particle thought experiment, the study suggests that extremal Kerr-Taub-NUT black hole cannot be over-spun; while near-extremal Kerr-Taub-NUT black hole can be over-spun. By comparing the two methods, the results indicate the time interval for particles crossing the black hole horizon might be important for consideration of the weak cosmic censorship conjecture.
