论文摘要
观察性证据和理论证据都表明流出源自积聚磁盘作为活性银河核（AGN）的基本要素。这些流出可能具有多个组件，例如无绑的超音速风和失败的风（FW）。后者是对辐射驱动磁盘流出的模拟的预测，这表明前者伴有内部失败的组件，在该组件中，该流程努力从超级大质量黑洞的强力拉力中逃脱。该FW组件可以提供一个物理框架来解释AGN的各种现象学成分。在这里，我们简要讨论其中的一些：宽线区域，X射线模糊者和X射线电晕。
Both observational and theoretical evidence point at outflows originating from accretion disks as fundamental ingredients of active galactic nuclei (AGN). These outflows can have more than one component, for example an unbound supersonic wind and a failed wind (FW). The latter is a prediction of the simulations of radiation-driven disk outflows which show that the former is accompanied by an inner failed component, where the flow struggles to escape from the strong gravitational pull of the supermassive black hole. This FW component could provide a physical framework to interpret various phenomenological components of AGN. Here we briefly discuss a few of them: the broad line region, the X-ray obscurer, and the X-ray corona.
