论文摘要
在本文中，我们研究了广义不确定性原理（GUP）对GUP修饰的Kerr Black Hole的阴影以及阴影半径与准模式（QNMS）的真实部分之间的对应关系的影响。我们发现，与Kerr真空溶液相比，GUP模型的Kerr黑洞的阴影曲率半径更大，并且随着GUP参数的增加而单调地增加了线性增加。然后，我们从拓扑的角度研究了阴影的内在曲率的特征点，以计算阴影的这些曲率半径的角度大小。为此，我们使用了M87*黑洞的EHT数据来限制GUP参数红色的上限，我们的结果是$β<10^{95} $。最后，我们探索了阴影半径与标量/电磁/重力QNM之间的联系。 GUP修饰的Kerr Black Hole还用于为三个微QuaSar的观察频率提供粒子振荡上和下频的完美曲线拟合，并限制了修改后的黑洞的校正参数值，以使其在经过修改的黑洞的度量标准中以非常合理的结合$β<10^{77} $。
In this paper we study the effect of the Generalized Uncertainty Principle (GUP) on the shadow of GUP-modified Kerr black hole and the correspondence between the shadow radius and the real part of the quasinormal modes (QNMs). We find that the shadow curvature radius of the GUP-modfied Kerr black hole is bigger compared to the Kerr vacuum solution and increases linearly monotonically with the increase of the GUP parameter. We then investigate the characteristic points of intrinsic curvature of the shadow from a topological point of view to calculate the the angular size for these curvature radii of the shadow. To this end, we have used the EHT data for the M87* black hole to constrain the upper limits of the GUP parameter red and our result is $β<10^{95}$. Finally, we have explored the connection between the shadow radius and the scalar/electromagnetic/gravitational QNMs. The GUP-modified Kerr black hole is also used to provide perfect curve fitting of the particle oscillation upper and lower frequencies to the observed frequencies for three microquasars and to restrict the values of the correction parameter in the metric of the modified black hole to very reasonable bound $β<10^{77}$.
