摘要

我们从观测的角度回顾了目前对射电星系和射电响亮类星体种群的理解，重点是它们的大尺度结构和动力学。我们讨论了射电星系的物理条件，它们的燃料和吸积模式，宿主星系和大尺度环境，以及它们在星系演化过程中作为反馈引擎所起的作用。最后，我们简要总结了射电星系群的其他天体物理学用途，包括宇宙磁性和宇宙学应用的研究，并讨论了推进我们对射电星系的物理和反馈行为的理解的未来前景。

Radio galaxies and feedback from AGN jets

We review current understanding of the population of radio galaxies and radio-loud quasars from an observational perspective, focusing on their large-scale structures and dynamics. We discuss the physical conditions in radio galaxies, their fuelling and accretion modes, host galaxies and large-scale environments, and the role(s) they play as engines of feedback in the process of galaxy evolution. Finally we briefly summarise other astrophysical uses of radio galaxy populations, including the study of cosmic magnetism and cosmological applications, and discuss future prospects for advancing our understanding of the physics and feedback behaviour of radio galaxies.
