摘要:

本文研究了广义不确定原理(GUP)对GUP修正的Kerr黑洞阴影的影响以及阴影半径与拟正规模实部的对应关系.我们发现GUP修正的Kerr黑洞的阴影曲率半径比Kerr真空解的大,并且随着GUP参数的增加而线性单调增加.然后,我们调查的特征点的内在曲率的阴影从拓扑的角度来看,计算的角度大小为这些曲率半径的阴影。为此,我们利用M87* 黑洞的EHT数据来限制GUP参数red的上限,得到了$β<10^{95}$ .最后,我们探讨了阴影半径和标量/电磁/引力QNM之间的联系。利用GUP修正的Kerr黑洞,对三个微类星体的粒子振荡上、下频率进行了曲线拟合,并将修正的黑洞度规中的修正参数限制在非常合理的$β<10^{77}$范围内.

英文摘要:

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 $β<10^{77}$.
