Ionized Gas in the Galaxy: A Southern Hemisphere Perspective with the Wisconsin H-Alpha Mapper

威斯康星大学麦迪逊分校的劳伦斯·哈夫纳博士和罗纳德·雷诺兹博士，以及盎格鲁-澳大利亚天文台的格雷戈里·马德森博士将把威斯康星h - α绘图仪（WHAM）搬到南半球的一个地点，用它在5年的时间里测量来自南方天空的h - α发射。最终的结果，当与WHAM的北方调查数据相结合时，将是一个分辨率为1度的全天调查，光谱分辨率为12公里/秒，超过200公里/秒的窗口。该项目的主要目标是推进我们对星际物质和银河系盘状和光晕内部过程的理解。正在进行的WHAM观测也为航空学、太阳系天文学、河外天文学和宇宙学领域做出了贡献。该项目还为本科生和研究生提供了参与的机会，并为整个天文学界提供了高质量的数据集。

Dr. Lawrence Haffner and Dr. Ronald Reynolds, at the University of Wisconsin at Madison, along with Dr. Gregory Madsen at the Anglo Australian Observatory will move the Wisconsin H-Alpha Mapper (WHAM) instrument to a southern hemisphere site, and use it to survey the H-alpha emission from the southern sky over the course of 5 years. The end result, when combined with data from WHAM's northern survey, would be an all-sky survey at a resolution of one degree with a spectral resolution of 12 km/s over a 200 km/s window. The primary goal of the project is to advance our understanding of interstellar matter and processes within the disk and halo of the Milky Way. Ongoing WHAM observations also contribute to the fields of aeronomy, solar system astronomy, extragalactic astronomy, and cosmology. The project also provides opportunities for undergraduate and graduate student involvement, and delivers high-quality datasets for use by the entire astronomical community.
