The Effect of Environment of Mass and Light in Spiral Galaxies

本研究探讨了星系中发光物质和暗物质的比例与星系环境之间的关系。光学光谱和21厘米线光谱将从相对密集和稀疏的空间区域的星系中获得。除了利用由此获得的旋转曲线来研究这些天体的质量分布外，测量到的平均速度还将用于研究相对较近的星系团系统的特殊运动。

This research investigates the relation between the proportion of luminous and dark matter in galaxies, and the environment of those galaxies. Both optical and 21 cm line spectra will be obtained from galaxies in both relatively dense and sparse regions of space. In additon to using the rotation curves thus obtained to study the mass distribution in these objects, the average velocity measured will be utilized to study peculiar motions of systems of relatively nearby clusters of galaxies.
