标题： The Spectral Energy Distributions of Active Galactic Nuclei

摘要： 我们介绍了关于活动星系核（AGN）光谱能量分布（SEDs）的正在进行的工作，这些工作基于X射线、紫外、光学、红外和无线电测光与光谱数据。 我们的工作受到新的广域成像巡天的推动，这些巡天将识别出大量的AGN，并且也是为了验证AGN SED拟合代码的需求。 我们构建了41个单独AGN的SEDs以及80个模拟赛弗特星系SEDs的额外SEDs。 所有我们的SEDs覆盖从0.09到30微米，而有些甚至延伸至X射线和/或无线电波段。 我们通过使用这些SEDs生成AGN测光红移来测试它们的实用性，结果显示它们优于之前文献中的SEDs，包括减少红移误差和流量密度残差。 显示英文摘要

摘要： We present ongoing work on the spectral energy distributions (SEDs) of active galactic nuclei (AGNs), derived from X-ray, ultraviolet, optical, infrared and radio photometry and spectroscopy. Our work is motivated by new wide-field imaging surveys that will identify vast numbers of AGNs, and by the need to benchmark AGN SED fitting codes. We have constructed 41 SEDs of individual AGNs and 80 additional SEDs that mimic Seyfert spectra. All of our SEDs span 0.09 to 30 microns, while some extend into the X-ray and/or radio. We have tested the utility of the SEDs by using them to generate AGN photometric redshifts, and they outperform SEDs from the prior literature, including reduced redshift errors and flux density residuals.
