标题： Cosmic Censorship and parametrized spinning black-hole geometries

摘要： “宇宙审查猜想”断言，由引力坍缩产生的所有奇点都隐藏在黑洞之内。 我们研究了这一猜想，在适用于广义相对论检验的设置中：与克尔解有参数偏差的小黑洞解。 这些解有一个旋转上限，超过该上限后，裸奇点将被外部观察者看到。 我们研究了这些（一般）时空是否可以通过点粒子或吸积盘被加速超过极端性。 我们的结果表明，对于一般的参数化，宇宙审查得以保持。 我们还给出了可以被加速超过极端性的特殊几何示例。 显示英文摘要

摘要： The ``cosmic censorship conjecture'' asserts that all singularities arising from gravitational collapse are hidden within black holes. We investigate this conjecture in a setup of interest for tests of General Relativity: black hole solutions which are parametrically small deviations away from the Kerr solution. These solutions have an upper bound on rotation, beyond which a naked singularity is visible to outside observers. We study whether these (generic) spacetimes can be spun-up past extremality with point particles or accretion disks. Our results show that cosmic censorship is preserved for generic parameterizations. We also present examples of special geometries which can be spun-up past extremality.
