The Low Surface Brightness Sky with the 48-Lens Dragonfly Telephoto Array

该团队将使用他们的长焦镜头阵列--蜻蜓--来观察来自星系的昏暗星光。这种微弱的光学信号以前从未被观测到。创新阵列位于新墨西哥州，在加拿大康涅狄格州或安大略省运营。观测结果将被用来测试暗淡星光的模型和模拟。该团队将继续与镜片制造商佳能发展工业联系。本科生和研究生将在仪器、软件和观测方面获得实践经验。该团队将使用他们专门建造的阵列来观测星系的低表面亮度恒星发射。他们的目标是研究(1)附近星系的外围，(2)发光的螺旋星系周围的暗矮星系，以及(3)Coma星系团和室女星系团中的超扩散星系。

The team will use their array of telephoto lenses, Dragonfly, to observe the dim starlight from galaxies. Such dim optical signals have never been observed before. The innovative array is located in New Mexico and operated from Connecticut or Ontario, Canada. The observations will be used to test models and simulations of the dim starlight. The team will continue to develop industrial links with Canon, a lens manufacturer. Undergraduates and graduate students will gain hands-on experience with instrumentation, software and observations.The team will use their purpose-built array to observe the low-surface-brightness stellar emission from galaxies. Their goals are to study (1) the outskirts of nearby galaxies, (2) the faint dwarf galaxies around luminous spiral galaxies, and (3) the ultra diffuse galaxies in the Coma Cluster and Virgo Cluster.
