论文摘要
从黑洞流出的电离结构背后的物理学尚未完全理解。在过去的二十年中，使用Chandra \ hetg光栅的档案观察结果，我们测量了9个活性星系中流出样品（AGN）的流出样品的吸收度量分布，即流出柱密度的依赖性，$ N_H $，在电离参数上，$ N_H $。 $ \ log（n_h）$ vs. $ \logξ$的坡度在0.00至0.72之间。我们发现流出的总柱密度与AGN光度对数之间的抗相关性，而黑洞质量和增生效率也没有。随着XRISM/RESOLVE SPECTROMETOR的发布，AGN流出诊断的诊断诊断可能会有所改善。我们利用其出色的分辨率和有效区域来研究通过从模拟分辨率光谱构建吸收测量分布来揭示流出电离结构的能力。解析会限制柱密度和HETG，但观察到了较短的观察。
The physics behind the ionization structure of outflows from black holes is yet to be fully understood. Using archival observations with the Chandra\HETG gratings over the past two decades, we measured an absorption measure distribution for a sample of outflows in nine active galaxies (AGNs), namely the dependence of outflow column density, $N_H$, on the ionization parameter, $ξ$. The slope of $\log(N_H)$ vs. $\logξ$ is found to be between 0.00 and 0.72. We find an anti-correlation between the log of total column density of the outflow and the log of AGN luminosity, and none with the black hole mass and accretion efficiency. A major improvement in the diagnostics of AGN outflows will potentially occur with the launch of the XRISM/Resolve spectrometer. We study the ability of Resolve to reveal the outflow ionization structure by constructing the absorption measure distribution from simulated Resolve spectra, utilizing its superior resolution and effective area. Resolve constrains the column density as well as HETG, but with much shorter observations.
