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.

类星体吸收流出对 AGN 反馈的贡献

确定类星体吸收从中心源 (R) 流出的距离及其动力学光度对于了解它们对活动星系核 (AGN) 反馈的贡献至关重要。在这里，我们总结了哈勃太空望远镜观测到的九个发光类星体样本的结果。我们发现超过一半的对象的流出足够强大，可以成为 AGN 反馈的主要代理，并且大多数流出发现在 R>100 pc 处。该样本代表了整个类星体吸收流出群体，并且不偏向特定范围的 R 和动态光度。因此，分析结果可以扩展到大多数此类天体，包括宽吸收线类星体。我们发现这些结果与另一个样本（七个类星体）的结果一致，该样本也对特定范围的 R 和动力学光度没有偏见。假设所有类星体都有吸收流出，我们得出结论，大多数发光类星体产生的流出可以对 AGN 反馈做出重大贡献。我们还讨论了流出的能量是否足以引起 AGN 反馈效应的标准。
