Interpretation of Modern Radio Surveys: Test of the Unification Paradigm

AST-0507529 Ivezic该项目将把几个现代射电目录统一到一个数据库中，并使用各种形态和光谱标准对源进行分类。 所产生的类的属性将分析与援助的国家的最先进的模型的射电源的演变和扩展，包括通过限制介质，同步加速器，绝热和逆康普顿损失的射流传播。 这一新的数据集在样本量、深度和波长覆盖方面使每一个旧的目录相形见绌，而且要使用的参数的多样性允许进行鲁棒的、自动化的、无监督的分类。 将对大量数据集的复杂统计分析与最先进的模型相结合，预计将提供新的定性见解，包括对射电源统一框架的可靠测试，大型统一数据库将促进现代统计方法在天文数据分析中的新应用，并将迅速向社会公布。 它还将允许更小的，独立的，但基于发现的项目，是理想的吸引本科生和研究生在尖端研究。 此外，该项目网站将促进高中生接触当前的研究，使他们能够（重新）发现许多预期的科学成果。

AST-0507529IvezicThis project will unify several modern radio catalogs into a single database, and classify the sources using various morphological and spectral criteria. The properties of the resulting classes will be analyzed with the aid of state-of-the-art models for radio source evolution and expansion that include jet propagation through confining media, and synchrotron, adiabatic and inverse Compton losses. This new data set dwarfs every older catalog in terms of sample size, depth and wavelength coverage, and the diversity of parameters to be used allows for robust, automated, unsupervised classification. Combining sophisticated statistical analysis of a massive data set with state-of-the art models is expected to provide qualitatively new insights, including a robust test of the radio source unification framework.The large unified database will foster novel applications of modern statistical methods to astronomical data analysis, and will be promptly released to the community. It will also allow smaller, stand-alone but discovery-based projects that are ideal for engaging undergraduate and graduate students in cutting-edge research. In addition, the project web site will promote the exposure of high school students to current research by enabling them to (re)discover many of the expected scientific results.
