AST-0507781BrothertonThis project will study how the wide range of observable quasar properties that give us the "zoo" of active galactic nuclei may be explained in terms of their fundamental physical characteristics. This includes a quantitative and empirical investigation of how the observational traits vary as a function of the physical parameters (mass, accretion rate, and so on), the calculation of spectral energy distributions (particularly for high-redshift quasars), and some consideration of rare quasar classes that can illustrate extreme physics or over-looked evolutionary phases. The principal sample will be that of the Sloan Digital Sky Survey, supplemented by other archival data and new observations where appropriate.The variety of quasar catalogs to be created will be of value to the wider astronomical community, and their development will train both graduate and undergraduate students. Educational and outreach efforts will focus upon how science fiction can be used to promote science to new and larger audiences, including resource material of value to teachers for years to come, and will include presentations at the NSF-supported Wyoming astronomy camp for high schools.

AST-0507781 Brothertonthis项目将研究如何根据其基本物理特征来解释各种可观察到的类星体特性，从而使我们有活跃的银河核的“动物园”。 这包括关于观察性状如何随物理参数（质量，增生率等）变化的定量和经验研究，光谱能量分布的计算（尤其是对于高红移类星体）的计算，以及对稀有的Quasar分类的考虑，可以说明极端物理学过度外观的较高物理学或外观过多的进化阶段。 主要样本将是Sloan Digital Sky调查的样本，并在适当的情况下补充了其他档案数据和新的观察结果。要创建的类星体目录对更广泛的天文学群落具有价值，其发展将培训毕业生和本科生。 教育和推广工作将集中于如何使用科学小说向新的和大型的受众推广科学，包括未来几年对教师的价值资源材料，并将包括在NSF支持的怀俄明州高中的天文营地的演讲。
