Clusters of Galaxies

星系团-9970884星系团格雷格正在对星系团进行三项截然不同但互为补充的观测研究。1.在以Fornax星系团为中心的4s x 3s区域进行完整的红移调查。使用基特峰国家天文台和加拿大夏威夷法国望远镜的广域CCD镶嵌成像仪研究彗星团。总体目标是了解星系和星系团作为一个整体的相互作用和演化是如何相互影响的。使用超大型阵列的第一次探测来搜索星系团。虽然有三个项目，但它们通过一条共同的科学线索联系在一起：了解星系团。这项工作为在光学和X射线搜索失效的远距离寻找大尺度结构提供了一种新的方法。

AST-9970884Clusters of GalaxiesMichael D. GreggDr. Gregg is conducting three distinct but complementary observational studies of clusters of galaxies. 1. conducting a complete redshift survey over a 4s x 3s region of sky centered on the Fornax cluster.2. studying the Coma cluster using a wide field CCD mosaiced imaging instrument at Kitt Peak National Observatory and the Canada Hawaii France Telescope. The overall goal to understand how the interactions and evolution of galaxies and the cluster as a whole affect each other.3. Using the Very Large Array's FIRST Survey to search for clusters of galaxies.Although there are three projects, they are linked by a common science thread: to understand clusters of galaxies. This work provides a new way to search for large scale structure at great distances where optical and x-ray searches become ineffective.***
