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 Brotherton该项目将研究如何根据活动星系核的基本物理特征来解释可观测到的类星体的广泛性质，这些性质为我们提供了活动星系核的“动物园”。 这包括对观测特征如何随物理参数（质量、吸积率等）而变化的定量和经验调查，光谱能量分布的计算（特别是对于高红移类星体），以及对稀有类星体的一些考虑，这些类星体可以说明极端的物理学或被忽视的演化阶段。 主要样本将是斯隆数字巡天的样本，并在适当的情况下辅以其他档案数据和新的观测数据。将要创建的各种类星体目录将对更广泛的天文学界有价值，它们的发展将培养研究生和本科生。 教育和推广工作将侧重于如何利用科幻小说向新的和更大的受众推广科学，包括未来几年对教师有价值的资源材料，并将包括在NSF支持的怀俄明州高中天文营的演讲。
