RUI: Cosmology and Astrophysics

这项研究的一部分涉及宇宙的加速，并将扩展Ia型超新星的经验确定和预测参数的比较，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约束，以及广义相对论的大规模测试。另一部分涉及对强大的经典双射电星系的物理特性的详细研究；检验这些宇宙学系统背后的假设；给出了13种新坐标距离的确定；以及用紧凑型射电源、双瓣射电星系和Ia型超新星获得的坐标距离的比较。这个项目将影响伯克-利哈伊山谷学院（BLVC）的本科生、业余天文学家和宾夕法尼亚州东部感兴趣的公众、初高中学生和教育工作者。它还将有助于留住和维持对科学感兴趣的BLVC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.
