论文摘要
我们分析了类星体SDSS J024221.87+004912.6的VLT/UVE观测值。我们识别四个吸收流出系统：$ v \ a的CIV BAL大约-18,000 \ text {km s}^{ - 1} $，以及三个较窄的低离子化系统，其质心速度范围从-1200到-3500 km S $ s $^{ - 1} $。这些流出显示与Arxiv研究的[OIII]流出相似的物理属性：1305.6922。我们发现其中两个系统足以有助于AGN反馈，其中一个系统达到了高于类星体的Eddington LuminiSusion的5％以上。我们还发现，该系统的距离为67 kpc距离类星体，这是最远的最远的小孔吸收流出距离其中心来源。此外，我们检查了BAL的时间变异性，并发现其速度单调增加，而槽本身会随着时间的流逝而变得更浅。
We analyze VLT/UVES observations of the quasar SDSS J024221.87+004912.6. We identify four absorption outflow systems: a CIV BAL at $v\approx -18,000 \text{ km s}^{-1}$, and three narrower low-ionization systems with centroid velocities ranging from -1200 to -3500 km s$^{-1}$. These outflows show similar physical attributes to the [OIII] outflows studied by arXiv:1305.6922. We find that two of the systems are energetic enough to contribute to AGN feedback, with one system reaching above 5% of the quasar's Eddington luminosity. We also find that this system is at a distance of 67 kpc away from the quasar, the farthest detected mini-BAL absorption outflow from its central source to date. In addition, we examine the time variability of the BAL, and find that its velocity monotonically increases, while the trough itself becomes shallower over time.
