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.

本研究探讨了在不同的年龄段， 星系中的亮物质和暗物质，以及它们的环境， 星系 将获得光学和21厘米线光谱 来自相对密集和稀疏的星系。 除了使用由此获得的旋转曲线来研究 这些物体的质量分布，测量到的平均速度 将被用来研究系统的特殊运动相对 附近的星系团
