摘要

电离锥和相对论喷流为我们提供了活动星系核(AGN)对星系内外周围气体环境影响的最大规模例子之一。对电离锥的研究不仅可以验证星系活动统一模型的预测，还可以探测星系气体环境，并追踪核的光度如何随时间变化(光回波)。在星系外甚至星系外的气体电离锥产生扩展发射线区域(eelr)，它可以跨越距离宿主星系几到几百千公里的距离。本文综述了近年来eelr中气体运动学及其电离特性的研究成果，特别关注了时间尺度为fewx(104−105)年的AGN辐射的衰落。本文还讨论了现代窄带和整场测量在这些研究中的作用。

Ionizing Spotlight of Active Galactic Nucleus

Ionization cones and relativistic jets give us one of the most large-scale example of active galactic nuclei (AGN) influence on the surrounding gas environment in galaxies and beyond. The study of ionization cones makes it possible not only to test the predictions of the unified model of galactic activity, but also to probe galaxy gas environment and trace how the luminosity of the nucleus changes over time (a light echo). In the external galactic or even extragalactic gas ionization cones create Extended Emission-Line Regions (EELRs) which can span distances from several to hundreds kpc away a host galaxy. We review the recent results of studying the gas kinematics and its ionization properties in EELRs with a special attention to search of fading AGN radiation on the time scale few×(104−105) years.The role of modern narrow-band and integral-field surveys in these researches is also considered.
