论文摘要
经典一般相对论中的无头发定理预测，旋转黑洞是由kerr公制指定的，kerr公制是由质量和自旋唯一识别的。然而，作为一项超越一般相对论的开创性研究，已经提出了旋转的毛茸茸的黑洞，其中包括克尔黑洞作为特殊情况。在这些黑孔中，由于周围的额外来源（例如暗物质或暗能量），可能会出现多余的头发。在这项工作中，我们在重力扰动方面研究了旋转毛茸茸的黑洞的现象学。特别是supperradiancianciancianciancianciancianciancianciancianciancianciance Lode Modes。使用匹配 - 肌电方法，我们得出了扩增因子和超沉载条件。我们还使用持续分数方法计算了准模式。结果与以前在Kerr限制中的研究非常吻合。我们还展示了如何响应毛茸茸的参数，黑洞自旋和量子数的变化而变化的放大和准模式。
The No Hair theorem in classical general relativity predicts that rotating black holes are specified by the Kerr metric, which is uniquely identified by the mass and spin. However, as a pioneering study beyond general relativity, the rotating hairy black hole has been proposed, which encompasses the Kerr black hole as a special case. In these black holes, there are extra hair which could appear due to the additional surrounding sources such as dark matter or dark energy. In this work, we study the phenomenology of the rotating hairy black hole in terms of gravitational perturbations. In particular, the supperradiance and the quasinormal modes. Using the matching-asymptotic method, we derive the amplification factor and the superradiance conditions. We also calculate the quasinormal modes using the continued fraction method. The results are in very good agreement with previous studies in the Kerr limit. We also show how the amplification and quasinormal modes will shift in response to variations in the hairy parameters, black hole spin, and quantum numbers.
