AST-0507465这项研究的一部分与宇宙的加速有关，并将扩展Ia型超新星的经验确定和预测参数的比较，以包括坐标距离的一阶和二阶导数，这将导致对宇宙学和模型参数的限制，并进行大规模的广义相对论检验。另一个部分涉及对强大的经典双射电星系的物理性质的详细研究；测试这些系统用于宇宙学背后的假设；确定一些例子的13个新的坐标距离；以及使用致密射电源、双叶射电星系和Ia型超新星获得的坐标距离的比较。这个项目将影响伯克斯-利哈伊谷学院(BLVC)的本科生，以及宾夕法尼亚州东部的业余天文学家和感兴趣的公众，以及初中生和教育工作者。它还将有助于留住和维持BLVC对科学感兴趣的女性学生。

AST-0507465DalyPart of this research relates to the acceleration of the Universe, and will extend the comparison of empirically determined and predicted parameters for type Ia supernovae to include the first and second derivatives of the coordinate distance, which will lead to constraints on cosmological and model parameters, and to large-scale tests of general relativity. Another part involves a detailed study of the physical properties of powerful classical double radio galaxies; tests of assumptions behind the use of those systems for cosmology; the determination of thirteen new coordinate distances for some examples; and the comparison of coordinate distances obtained using compact radio sources, double lobe radio galaxies, and type Ia supernovae.This project will impact undergraduate students at Berks-Lehigh Valley College (BLVC), an undergraduate institution, as well as amateur astronomers and the interested public in eastern Pennsylvania, and middle and high school students and educators. It will also help to retain and sustain female BLVC students interested in science.
