论文摘要
在标量扰动下研究了通过重力脱钩（GD）方法获得的毛黑洞溶液的行为。这种溶液的准模式频率受GD头发调节。数值生成的波解决方案是针对GD毛茸茸的黑洞参数的一系列值得出的，其高频模式对它们非常敏感。结果与Schwarzschild解决方案相应的结果面临，其偏差证明了GD毛茸茸的黑洞的独特物理鉴定。这里提出的方法包括在地面探测器处获得GD毛茸茸的黑洞的可观察特征的第一步，这些探测器是通过在RINGDOWN阶段融合GD毛茸茸的黑洞合并的二元系统发出的。
The behavior of hairy black hole solutions, obtained by the gravitational decoupling (GD) method, is investigated under scalar perturbations. The quasinormal mode frequencies of such solutions are regulated by GD hair. The numerically generated wave solutions are derived for a range of values for the GD hairy black hole parameters, with higher-frequency modes very sensitive to them. The results are confronted with the corresponding ones for the Schwarzschild solution, whose deviations from it demonstrate a unique physical identification of GD hairy black holes. The method here presented comprises the first steps towards the obtainment of the observable signature of GD hairy black holes at ground-based detectors, emitted from coalescing binary systems of GD hairy black hole mergers in the ringdown phase.
