标题： Imprints of a high velocity wind on the soft x-ray spectrum of PG 1211+143

摘要： 2014年的一项延长的XMM-Newton观测揭示了明亮窄线赛弗特星系PG 1211+143中更为复杂的高能风，这种风的不同成分可以通过速度、电离程度和柱密度来区分。 我们在此报告了从电离外流中检测到的软X射线发射和吸收特征，发现了与最近在高度电离的Fe K吸收光谱中识别出的两个高能速度分量v ~ 0.129c和v ~ 0.066c相对应的特征。 共移动软X射线吸收剂的较低电离度表明存在分布更密集的云团嵌套在主要外流中，而硬X射线谱中相同流分量的更高列密度则暗示了连续X射线源的不同视线方向。 显示英文摘要

摘要： An extended XMM-Newton observation of the luminous narrow line Seyfert galaxy PG 1211+143 in 2014 has revealed a more complex high velocity wind, with components distinguished in velocity, ionization level, and column density. Here we report soft x-ray emission and absorption features from the ionized outflow, finding counterparts of both high velocity components, v ~ 0.129c and v ~ 0.066c, recently identified in the highly ionized Fe K absorption spectrum. The lower ionization of the co-moving soft x-ray absorbers imply a distribution of higher density clouds embedded in the main outflow, while much higher column densities for the same flow component in the hard x-ray spectra suggest differing sight lines to the continuum x-ray source.
