论文摘要
Spitzer空间望远镜彻底改变了活性银河核（AGNS）的研究。它在中红外波长下的合并灵敏度和映射速度显示出大量高度刺激的AGN人群。该人群意味着比光学和X射线调查所示的黑洞的辐射吸积效率更高，因此黑洞的自旋可能更高。 Spitzer的独特中印刷光谱学能力为AGN周围灰尘的分布和性质提供了重要的见解，使AGN和Starburst组件的分离，从热灰尘中检测硅酸盐特征以及与AGN活性相关的震惊气体的识别。 Spitzer的敏感性几乎可以完全识别X射线和无线电中选择的AGN样品的宿主星系。当我们期待詹姆斯·韦伯（James Webb）太空望远镜时，从Spitzer研究中学到的教训将为您提供新的和即将到来的红外设施的观察计划。
The Spitzer Space Telescope revolutionized studies of Active Galactic Nuclei (AGNs). Its combined sensitivity and mapping speed at mid-infrared wavelengths revealed a substantial population of highly-obscured AGNs. This population implies a higher radiative accretion efficiency, and thus possibly a higher spin for black holes than indicated by surveys in the optical and X-ray. The unique mid-infrared spectrographic capability of Spitzer gave important insights into the distribution and nature of the dust surrounding AGNs, enabling the separation of AGN and starburst components, the detection of silicate features in emission from hot dust, and the identification of shocked gas associated with AGN activity. The sensitivity of Spitzer allowed almost complete identification of the host galaxies of samples of AGNs selected in the X-ray and radio. As we look forward to the James Webb Space Telescope, the lessons learned from Spitzer studies will inform observational programs with new and upcoming infrared facilities.
