论文摘要
银河核中黑洞(BH)活性的基本平面(FP)将X射线和无线电照明与BH质量和增生率联系起来。但是,数据显示了一个大散射,这激发了我们进行新变量。我们将BH自旋作为新变量添加,并根据无线电和X射线发光性估计射流功率和磁盘光度的自旋依赖性。我们将Blandford-Znajek过程作为流出的主要来源,并发现射流功率取决于BH旋转在中度和大型旋转值下的旋转强。我们对具有亚埃德丁顿积聚率的10个AGN进行统计分析,并通过反射或连续拟合方法独立测量其自旋值,并发现依赖自旋的关系可以更好地描述数据。如果支持更多数据,则该分析不仅可能意味着FP关系的旋转依赖性,还可能暗示AGN Jets中的Blandford-Znajek过程。
The Fundamental Plane (FP) of Black Hole (BH) Activity in galactic nuclei relates X-ray and radio luminosities to BH mass and accretion rate. However, there is a large scatter exhibited by the data, which motivated us for a new variable. We add BH spin as a new variable and estimate the spin dependence of the jet power and disk luminosity in terms of radio and X-ray luminosities. We assume the Blandford-Znajek process as the main source of the outflow, and find that the jet power depends on BH spin stronger than quadratically at moderate and large spin values. We perform a statistical analysis for 10 AGNs which have sub-Eddington accretion rates and whose spin values are measured independently via the reflection or continuum-fitting methods, and find that the spin-dependent relation describes the data significantly better. This analysis, if supported with more data, could imply not only the spin dependence of the FP relation, but also the Blandford-Znajek process in AGN jets.
