论文摘要
确定类星体吸收的距离与中央源（R）及其动力学发光度的距离对于理解它们对活性银河核（AGN）反馈的贡献至关重要。在这里，我们总结了使用哈勃太空望远镜观察到的9个发光类星体样本的结果。我们发现，一半以上对象的流出功能足以成为AGN反馈的主要代理，并且大多数流出都在R> 100 PC上找到。该样品代表了整个类星体吸收流出群体，并且对R和动力学光度的特定范围无偏见。因此，分析结果可以扩展到大多数此类对象，包括广泛的吸收线类星体。我们发现，这些结果与另一个样品（七个类星体）的结果一致，这些样品也对R和动力学发光度的特定范围没有偏见。假设所有类星体都有吸收流出，我们得出的结论是，大多数发光的类星体产生的流出会对AGN反馈产生重大贡献。我们还讨论了流出是否足够充满活力以引起AGN反馈效应的标准。
Determining the distance of quasar absorption outflows from the central source (R) and their kinetic luminosity are crucial for understanding their contribution to active galactic nucleus (AGN) feedback. Here we summarize the results for a sample of nine luminous quasars that were observed with the Hubble Space Telescope. We find that the outflows in more than half of the objects are powerful enough to be the main agents for AGN feedback, and that most outflows are found at R>100 pc. The sample is representative of the quasar absorption outflow population as a whole and is unbiased towards specific ranges of R and kinetic luminosity. Therefore, the analysis results can be extended to the majority of such objects, including broad absorption line quasars. We find that these results are consistent with those of another sample (seven quasars) that is also unbiased towards specific ranges of R and kinetic luminosity. Assuming that all quasars have absorption outflows, we conclude that most luminous quasars produce outflows that can contribute significantly to AGN feedback. We also discuss the criterion for whether an outflow is energetic enough to cause AGN feedback effects.
