glimpse360

glimpse360将映射剩下的187度还没有被观察到的斯皮策太空望远镜在银河系平面。调查将覆盖经度L = 65-265度不含升〜102-109和升〜76-82。纬度范围将是3.1度,比以前的一瞥调查(2度),因为磁盘耀斑在外星系更宽。纬度中心将遵循银河翘曲。

Three visits on each sky position with 0.6&12s HDR frames will provide a high dynamic range of sensitivity that exceeds both 一瞥 and the planned WISE mission surveys at both ends. This will allow us to determine the edge of the Galactic stellar disk, study low and high mass star formation in the nearby Perseus arm as well as in the Far Outer Galaxy, and study evolved stars throughout the Galaxy.

The combination of glimpse360 and the previous GLIMPSE (abs(l)<65 deg.) and smaller surveys will provide us with a lasting global dataset, encompassing most of the stars and star formation in our Galaxy. This database will allow us to determine the star-formation rate in the Galaxy, how the stellar disk scale heights and lengths vary across the Galaxy, and how the dust extinction law varies with location in the disk. In addition, we will catalog stars, star clusters, PAH bubbles, supernova remnants, infrared dark clouds, outflows from massive protostars, planetary nebulae, external galaxies in the Zone of Avoidance, and many other types of objects. Following the tradition of the previous 一瞥 Legacy programs, we will deliver enhanced data products for the survey-source lists and cleaned mosaics-to the community.
