论文摘要
我们介绍了在类星体SDSS J1130+0411（$ Z \ 3.98 $）中观察到的六个流出的吸收槽的分析，径向速度范围从$ -2400 $到$ -15,400 $ $ km S $^{ - 1} $。这些光谱是在$ 1135-1890 $Å$ 1135-1890 $Å上的非常大的望远镜/紫外线和视觉梯形光谱仪上拍摄的。在主要流出系统中（$ V \ -3200 $ km s $^{ - 1} $），我们确定Fe II和几个Fe II*吸收槽以及Si II和Si II和Si II*槽，我们用来确定电子数量$ \ log $ \ log n_e = 2.6 _ = 2.6 _ _ _ _ _ _ _ { - 0.7} { - 0.7}^$ com}使用这些和其他离子的列密度，我们确定具有氢柱密度$ \ log n_h = 21.44 _ { - 0.33}^{+0.24} $ CM $^{ - 2} $和IONIVIAL参数$ \ log u_h = -1.75 = -1.75 _ _ { - 0.45}的光电离子化解决方案。从这些值中，我们得出距离$ r = 16 _ { - 11}^{+23} $ kpc，平均质量流量$ \ dot {m} = 4100 _ { - 2400}^{+6600} $ $ $ m _ {\ odot} \ dot {e} _k = 46.13 _ { - 0.37}^{+0.41} $ erg s $^{ - 1} $。这个$ \ dot {e} _k $是$ 1.4 _ { - 0.8}^{+2.2} $％的类星体爱丁顿光度，因此对AGN反馈做出了重大贡献。
We present the analysis of the absorption troughs of six outflows observed in quasar SDSS J1130+0411 ($z \approx 3.98$) with radial velocities ranging from $-2400$ to $-15,400$ km s$^{-1}$. These spectra were taken with the Very Large Telescope/Ultraviolet and Visual Echelle Spectrograph over the rest frame wavelength range of $1135-1890$ Å. In the main outflow system ($v \approx -3200$ km s$^{-1}$), we identify Fe II and several Fe II* absorption troughs as well as Si II and Si II* troughs, which we use to determine the electron number density $\log n_e = 2.6_{-0.7}^{+0.8}$ cm$^{-3}$. Using the column densities of these and other ions, we determine a photoionization solution with hydrogen column density $\log N_H = 21.44_{-0.33}^{+0.24}$ cm$^{-2}$ and ionization parameter $\log U_H = -1.75_{-0.45}^{+0.28}$. From these values we derive the distance $R = 16_{-11}^{+23}$ kpc, the average mass flow rate $\dot{M} = 4100_{-2400}^{+6600}$ $M_{\odot}$ yr$^{-1}$, and the kinetic luminosity $\log \dot{E}_k = 46.13_{-0.37}^{+0.41}$ erg s$^{-1}$. This $\dot{E}_k$ is $1.4_{-0.8}^{+2.2}$% of the quasar's Eddington luminosity, and therefore contributes significantly to AGN feedback.
