A Comprehensive Spectroscopic Study of Gravitationally Lensed Dwarf Galaxies at the Peak Epoch of Star Formation

该小组将研究天文学家已知的最遥远的矮星系。 矮星系位于星系团的后面。 前景星系团的引力透镜增强了来自遥远矮星系的信号。 这个技巧让研究小组观察到了原本看不见的矮星系。 来自地面和太空的观测将显示矮星系如何形成恒星并影响其环境。 高级团队成员将培训初级团队成员。 该小组将与当地高中代表性不足的学生接触，特别是滨江县少年霍尔斯的学生。 该小组还将开发教师培训的在线材料。该小组将调查z ~ 1. 5 - 3. 6的矮星系。 他们的目标是：（1）对200个被星系团透镜化的矮星系进行光学和近红外波长的地面光谱学测量;（2）将这些测量与现有的天基测量相结合;（3）检查莱曼连续体逃逸分数、尘埃消光、气体流出、金属丰度和星星形成的“突发性”。

The team will study the most distant dwarf galaxies known to astronomers. The dwarf galaxies are located behind clusters of galaxies. Gravitational lensing by the foreground clusters boosts the signals from the distant dwarf galaxies. This trick lets the team observe the otherwise-invisible dwarf galaxies. Observations from the ground and space will show how the dwarf galaxies form their stars and affect their environments. Senior team members will train junior team members. The team will engage with underrepresented students in local high schools, notably those of the Riverside County Juvenile Halls. The team will also develop online materials for teacher training.The team will investigate dwarf galaxies at z ~ 1.5-3.6. Their goals are to (1) conduct ground-based spectroscopy at optical and near-infrared wavelengths of 200 dwarf galaxies lensed by galaxy clusters; (2) combine those measurements with existing space-based measurements; and (3) examine the Lyman continuum escape fractions, the dust extinction, the gas outflows, the metallicities, and the "burstiness" of the star formation.
