论文摘要
我们分析了从Uves光谱类星体吸收数据库中检索的类星体SDSS J143907.5-010616.7的VLT/UVES频谱。我们在频谱中识别两个流出系统：一个迷你宽吸收系（迷你孔）系统和狭窄的吸收系（NAL）系统。我们测量了迷你孔的离子柱密度（$ v = -1550 $ km s $^{ - 1} $）流出，该流量具有Fe II的激发状态吸收槽。我们确定电子密度$ \ log {n_e} = 3.4^{+0.1} _ { - 0.1} $基于Fe II的激动状态和基态丰度之间的比例，并发现流出的动力学光度为$ \ lysesim 0.1 \％的Quasim Eddington fefted feardton feardton feardton feardton feardto feardto feardton fearding fearting fearting fording fearting fording fearting inftington fearting insuff insuff insuff insuff insuff。
We analyze the VLT/UVES spectrum of the quasar SDSS J143907.5-010616.7, retrieved from the UVES Spectral Quasar Absorption Database. We identify two outflow systems in the spectrum: a mini broad absorption line (mini-BAL) system and a narrow absorption line (NAL) system. We measure the ionic column densities of the mini-BAL ($v=-1550$ km s$^{-1}$) outflow, which has excited state absorption troughs of Fe II. We determine that the electron number density $\log{n_e}=3.4^{+0.1}_{-0.1}$ based on the ratios between the excited and ground state abundances of Fe II, and find the kinetic luminosity of the outflow to be $\lesssim 0.1 \%$ of the quasar's Eddington luminosity, making it insufficient to contribute to AGN feedback.
