论文摘要
类星体光谱中的广泛吸收线（BAL）特征揭示了中央超级黑洞的能量流出的明确特征，因此BAL类星体是研究星系上的发光准反馈的潜在过程的主要目标。我们分析了使用新颖的光谱合成代码Simbal（Leighly et al.2018）的“重叠槽”低离子宽吸收线Quasar（Felobal）SDSSSSSSSSSSSSSSSSSSSSSSSSSSSS SDSS SDSS SDSS SDSS SDSS SDSS SDSS SDSS SDSS SDSS SDSS SDSS SDSS SDSS SDSS SDSS的静止光谱使用（Leighly等人，2012年）），并发现了一个非凡的快速和能量的BAL OUTFLOW。我们的分析表明，到达$ \ sim -38000 \ rm \，km \，s^{ - 1} $的流出速度，速度宽度为$ \ sim 10000 \ rm \，km \，km \，s^{ - 1} $，这是最大的Felobal Exflow Velobal Efflflow Velocity velocity velocity Leasitured tore water to at Date to at Date to at Date to dow to dow to dow to dot。流出气体的列密度为log $ n_h \ sim23.2 \，[\ rm cm^{ - 1}] $，带有log动力学光度$ \ log l_ {ke} \ sim48.1 $ [erg $ \ $ \ rm s^{ - 1} $]，超过了Quastribal filemin和quas fie quasribal fie quasribal for quasrial for quasribal and quarriber for quasribal for quarar＆quar。流出的能源估计远大于先前报告的任何BAL对象的估计值。 该对象还显示“异常的红色”和我们能够用Simbal建模的显着散射组件。我们发现，在额外的零速度吸收成分中进行辐射滤波的第一个确定性案例，该病例需要吸收的连续体生成观察到的特定吸收线（MGII，ALIII和ALII），而又不会产生高电离线（例如CIV）。
Broad absorption line (BAL) features in quasar spectra reveal an unambiguous signature of energetic outflows from central supermassive black holes, and thus BAL quasars are prime targets for investigating the potential process of luminous quasar feedback on galaxies. We analyzed the rest-UV spectrum of an "overlapping trough" iron low-ionization broad absorption line quasar (FeLoBAL) SDSS J135246.37+423923.5 using the novel spectral synthesis code SimBAL (Leighly et al. 2018) and discovered an extraordinarily fast and energetic BAL outflow. Our analysis revealed outflow velocities reaching $\sim -38000\rm \, km\, s^{-1}$ with a velocity width of $\sim 10000\rm \, km\, s^{-1}$ which is the largest FeLoBAL outflow velocity measured to date. The column density of the outflow gas is log$N_H\sim23.2\,[\rm cm^{-1}]$ with the log kinetic luminosity $\log L_{KE}\sim48.1$ [erg $\rm s^{-1}$] which exceeds the bolometric luminosity of the quasar and is energetic enough to effectively drive quasar feedback. The energy estimate for the outflow is far greater than the estimates from any BAL object previously reported. The object also shows "anomalous reddening" and a significant scattered component that we were able to model with SimBAL. We found the first definitive case for radiation filtering in an additional zero-velocity absorption component that required an absorbed continuum to produce the particular absorption lines observed (MgII, AlIII and AlII) without also producing the high ionization lines such as CIV.
