High Resolution Observational Studies of the Structure and Evolution of Galaxies

这项研究的目的是确定分布，运动， 和物理条件的各种组成部分， 星系中的星际介质 目的是研究 这些组成部分之间的关系， 结构和星系中星星的形成过程。 虽然一般的进化周期之间的星际 介质和星系中的恒星被理解，详细的 根本的过程仍然没有明确的描述。 为了研究外星系中的星际介质 在足够的分辨率下，主要研究者将使用 相对较新的帽子溪毫米波长望远镜， 观察中性原子氢（HI）成分和非常 大阵列（VLA）射电望远镜观察分子 成分和相对论电子。 光学成像 法布里-珀罗光谱仪将用于探测电离气体。 这种比较详细的分析将进一步了解 银河系演化的基本过程 星系如何 与时俱进与许多基本问题有关， 天文学，如星系的形成，宇宙学，和起源， 星系的结构及其形态类型。

The research is aimed at determining the distribution, motions and physical conditions of the various components of the interstellar medium in galaxies. The purpose is to study the relationship of these components to each other, to the spiral structure, and to the star formation processes in galaxies. While the general evolutionary cycle between the interstellar medium and the stars in galaxies is understood, the detailed underlying processes are still not clearly delineated. In order to study the interstellar medium in external galaxies with sufficient resolution, the Principal Investigators will use the relatively new Hat Creek millimeter-wavelength telescope to observe the neutral atomic hydrogen (HI) component and the Very Large Array (VLA) radio telescope to observe the molecular component and the relativistic electrons. An optical imaging Fabry-Perot spectrometer will be used to probe the ionized gas. Such comparative detailed analyses will further the understanding of the basic processes of galactic evolution. How galaxies evolve with time has relevance to many basic questions in astronomy such as galaxy formation, cosmology, and the origin of the structure of galaxies and of their morphological types.
