Observational Study of the Formation and Evolution of Galaxies using the Subaru Telescope

为了了解星系的形成和演化，我们使用斯巴鲁8.2米望远镜上的Suprime-Cam对遥远的暗星系进行了非常深的成像调查。为此，我们构建了一个新的中间带滤波器系统，该系统由20个高质量的滤波器组成，光谱分辨率为R=23。此外，我们还制作了一套窄带滤光片。使用这些滤镜，我们获得了目标天空区域的几张深度图像。我们发现了大量的红移为3.7的莱曼α发射体。此外，我们成功地探测到非常遥远的星系在红移5.7，这是遥远的已知的。这些数据被用来研究宇宙星星的形成历史，从z=5.7到3.7。

In order to understand the formation and evolution of galaxies, we have carried out very deep imaging survey for faint, distant galaxies using the Suprime-Cam on the Subaru 8.2 m telescope. For this purpose, we constructed a new intermediate-band filter system which consists of 20 high-quality filters with a spectroscopic resolution of R=23. Further, we have also made a set of narrow-band filters. Using these filters, we obtained several deep images of our targeted sky areas. We have found a large number of Lyman α emitters at redshift of 3.7. Further we succeeded in detecting very distant galaxies at redshift of 5.7 which are distant known so far. These data are utilized to investigate the cosmic star formation history from z=5.7 to 3.7.
