The Galactic Ring Survey

银河系主要的恒星形成结构，5千秒环，在很大程度上仍未被探索。波士顿大学的詹姆斯·杰克逊博士和他的同事们利用五所大学射电天文台14米望远镜上的新型SEQUOIA多像素阵列接收器，正在对银河系内部进行一项新的分子线调查——波士顿大学五所大学射电天文台星系环调查（GRS）。在该奖项的评选过程中，团队将完成四项重点科研项目：对GRS期间发现的分子云和云核进行编目。2. 建立分子云及其内嵌红外恒星形成区域的运动距离。3. 确定银河系内部的结构，特别是5千秒环的结构。4. 分子云内部结构的量化和测试模型。完成后，GRS将成为银河系内部分子气体分布的最终地图，它将成为几代银河系天文学家的重要资源。＊＊＊

AST 0098562JacksonThe Milky Way's dominant star-forming structure, the 5 kiloparsec ring, remains largely unexplored. Using the new SEQUOIA multi-pixel array receiver on the Five College Radio Astronomy Observatory 14-meter telescope, Dr. James Jackson and his colleagues at Boston University are conducting a new molecular line survey of the inner Galaxy -- the Boston University--Five College Radio Astronomy Observatory Galactic Ring Survey (GRS). During the course of this award, the group will complete four key science projects: 1. Cataloging molecular clouds and cloud cores discovered during the GRS. 2. Establishing kinematic distances to molecular clouds and their embedded infrared star-forming regions. 3. Determining the structure of the inner Milky Way, and especially that of the 5 kiloparsec ring. 4. Quantifying and testing models of the internal structure of molecular clouds. When complete, the GRS will be the definitive map of the molecular gas distribution in the inner Galaxy, and it will be a vital resource for generations of Galactic astronomers. ***
