Testing the AGN unified scheme for the most luminous 3CR radio galaxies and quasars

虽然在观测上至少有十几类活动星系核（AGN）是可辨别的，但本质上，根据统一概念，类别的多样性可能会减少。在这里，我们希望探索活动星系核在高光度下的统一。为了克服方向相关的消光，需要进行红外观测。该项目基于斯皮策太空望远镜对z>1的3CR射电星系和类星体的中红外观测：

While observationally at least a dozen classes of Active Galactic Nuclei (AGN) are discernible, intrinsically the diversity of classes may be reduced according to unification concepts. Here we wish to explore unification of AGN at high luminosity. To overcome the orientation-dependent extinction, infrared observations are required. The project is based on approved mid-infrared observations of 3CR radio galaxies and quasars at z>1 with the Spitzer Space Telescope:1) For the 20 bright sources at 1
