论文摘要
活性银河核（AGN）现象是由一个超级质量的黑洞产生的，其周围的气态和尘土飞扬的材料。红外（IR）制度提供了大多数信息，以表征从银河系到黑洞桥接的尘土结构，从而为黑洞生长和宿主星系演变提供了线索。在过去的几十年中，通过观察设施的各种地面，空中和空间IR的调试，我们对AGN环形结构的解释通过改进了对它们的粉尘发射如何随波长的函数的变化以及尘土结构的加热对从中央发动机释放的能量变化的加热作用，从而显着提高。在这篇综述中，我们总结了当前对AGN IR宽带光谱能量分布（SED）的观察知识以及IR时间可变性行为，涵盖了巨大的AGN光度和红移范围，并讨论了可以通过将相关观察图像整合到相关的观察图中获得的晦涩结构和托管星系的一阶见解。
The active galactic nucleus (AGN) phenomena results from a supermassive black hole accreting its surrounding gaseous and dusty material. The infrared (IR) regime provides most of the information to characterize the dusty structures that bridge from the galaxy to the black hole, providing clues to the black hole growth and host galaxy evolution. Over the past several decades, with the commissioning of various ground, airborne and space IR observing facilities, our interpretations of the AGN circumnuclear structures have advanced significantly through improved understanding of how their dust emission changes as a function of wavelength and how the heating of the dusty structures responds to variations of the energy released from the central engine. In this review, we summarize the current observational knowledge of the AGN IR broad-band spectral energy distributions (SEDs) and the IR time variability behavior covering large ranges of AGN luminosity and redshift, and discuss some first-order insights into the obscuring structures and host galaxy IR properties that can be obtained by integrating the relevant observations into a coherent picture.
