论文摘要
我们介绍了两个流出（S1 at -5500 km s $^{ - 1} $和S2 at -9700 km s $^{ - 1} $）的分析。流出被检测为来自两个高电源物种的吸收槽，包括N III，O III和S IV，以及包括AR VIII，NE VIII和NA IX在内的非常高的Iriations物种。派生的光电离解决方案表明，每个流出都需要两个电离相解。对于S1，来自S IV*和S IV的槽允许我们得出电子密度，$ n_ {e} $ = 1.8 $ \ times $ 10 $^4 $ cm $^{ - 3} $，以及与$ r $ $ $ = 270 pc的中心来源的距离。对于S2，来自O III*和O III的低谷$ N_ {E} $ = 1.2 $ \ times $ 10 $^3 $ cm $^{ - 3} $和$ r $ = 1600 pc。 S2的动力学光度为$> $ $的$ 12％，因此可以提供强大的AGN反馈效果。两个流出系统中O III和O VI的吸收槽的比较支持了这样的想法：对于给定的元素，较高的电离离子的覆盖率比较低的电离分数更大。
We present the analysis of two outflows (S1 at --5500 km s$^{-1}$ and S2 at --9700 km s$^{-1}$) seen in recent HST/COS observations of quasar SDSS J0755+2306 (z = 0.854). The outflows are detected as absorption troughs from both high-ionization species, including N III, O III, and S IV, and very high-ionization species, including Ar VIII, Ne VIII, and Na IX. The derived photoionization solutions show that each outflow requires a two ionization-phase solution. For S1, troughs from S IV* and S IV allow us to derive an electron number density, $n_{e}$ = 1.8$\times$10$^4$ cm$^{-3}$, and its distance from the central source of $R$ = 270 pc. For S2, troughs from O III* and O III yield $n_{e}$ = 1.2$\times$10$^3$ cm$^{-3}$ and $R$ = 1600 pc. The kinetic luminosity of S2 is $>$ 12% of the Eddington luminosity for the quasar and therefore can provide strong AGN feedback effects. Comparison of absorption troughs from O III and O VI in both outflow systems supports the idea that for a given element, higher ionization ions have larger covering fractions than lower ionization ones.
