A High-Resolution, High Sensitivity H-alpha and {Sll} Surveyof the Northern Galaxy

9800476 SIMONETTI高分辨率、高灵敏度的H-α和SiI测量。该项目的目标是对从北半球可见的那部分银河系的星际线发射进行两次主要的成像调查。第一次调查将包括北天球上空温暖的电离星际介质发出的微弱的氢巴尔默-阿尔法辐射的图像。第二次探测将包括电离硫的星际禁线发射图像，覆盖银河系北部正负20度纬度之间的区域。这些测量的结果将以数字地图集的形式提供给天文学团体。

9800476 Simonetti A High-Resolution, High-Sensitivity H-alpha and SII Survey of the Northern Galaxy. The objective of this project is the production of two major imaging surveys of interstellar line emission from that part of the Galaxy visible from the northern hemisphere. The first survey will consist of images of the faint hydrogen Balmer-alpha emission from the warm ionized interstellar medium over the northern celestial hemisphere. The second survey will comprise images of the interstellar forbidden line emission of ionized sulfur, and will cover the northern Galaxy between latitudes of plus/minus 20 degrees. The results of the surveys will be digital atlases available to the astronomical community.
