项目摘要

AST-0708967GallagherDr. John Gallagher of the University of Wisconsin at Madison will carry out a study of starburst activities in nearby galaxies, making spectroscopic and imaging observations with telescopes of the WIYN (Wisconsin-Indiana-Yale-National Optical Astronomy Observatory) Observatory and with SALT (the Southern African Large Telescope). First, he will investigate the relationship between young stellar systems within starbursts, compact massive star clusters and starburst clumps, and the state of the interstellar medium. Second, he will study how young stellar populations in starbursts connect to galactic winds and widespread gas ionization. The data will be compared with models of stellar populations, enabling studies of astrophysical processes inside these extreme objects, which are likely to apply in rapidly star-forming young galaxies at redshifts of two and above, where the majority of the present day stellar mass was probably produced.The research activities involve student training and international collaboration. Undergraduates will gain access to this project through the NSF-REU (Research Experiences for Undergraduates) program. The team will continue its participation in the very popular "Universe in the Park" program, where students bring small telescopes to state parks in Wisconsin and open the skies to the public. Exchange programs will be carried out with South Africa and other countries.

AST-0708967-Gallagherdr。威斯康星大学麦迪逊分校的约翰·加拉格尔（John Gallagher）将对附近星系中的Starburst活动进行研究，并通过Wiyn（Wisconsin-Indiana-Indiana-Yale-Yale-National-National Optical Astromanty天文台）和盐（南非大型望远镜）进行光谱和成像观察。首先，他将研究Starbursts中年轻的恒星系统，紧凑的大型星团和Starburst团块以及星际介质的状态之间的关系。其次，他将研究Starbursts中的年轻恒星种群如何与银河风和广泛的气体电离相连。将数据与恒星种群的模型进行比较，从而使这些极端物体内的天体物理过程进行研究，这些物体可能会适用于在两个及以上的红移迅速形成的年轻星系中，在当今的大部分恒星质量可能是在当今的大部分恒星质量。大学生将通过NSF-REU（本科生的研究经验）计划进入该项目。该团队将继续参加非常受欢迎的“公园中的宇宙”计划，在那里学生将小型望远镜带到威斯康星州的州立公园，并向公众开放天空。交流计划将与南非和其他国家一起实施。
