项目摘要

In this research project, we developed a new-type spectrograph called "FMOS" to mount a fiber multiple-object spectrograph on the Subaru telescope, which has a prime focus for wide-field observations. The goal of this study is "Study of Formation Process of Galaxies and Quasars" as shown in the title of this project. The spectrograph has the capability of 400 multiplicity with a wavelength range from optical 0.9 micron to infrared 1.8 micron. We expected to obtain the clue to the solution of galaxies and quasars formation during the test observation program targeting quasars and galaxies located at moderately early universe with a redshift of 2-5. Although we made test observations with the corrector lenses and the mechanical stages twice, the test observations targeting distant quasars and galaxies are delayed by the problems on the prime-focus unit and by the difficulties in the adjustment of the complicated spectrograph system. On the other hand, the various research plans using the FMOS have been discussed more than expected with great expectations of its wide-field and multiplicity capabilities. Accordingly, we report the mechanical development of the FMOS in detail and the advanced research plan using this instrument attached to the prime focus of the large telescope. In particular, the cooling capability of the infrared spectrograph, optical performance of the whole 'system, the characteristics of the detector and control electronics, and the interface between the control software and the archive systems are reported as the instrumentation items, systematic study of the galaxy formation, and the survey project of dark energy are also reported as the result of the discussion of the test observation plan. The full-fledged observational study is expected from the fiscal year of H19.

在这个研究项目中，我们开发了一种名为“FMOS”的新型摄谱仪，将光纤多目标摄谱仪安装在斯巴鲁望远镜上，该望远镜主要用于宽视场观测。正如该项目的标题所示，本研究的目标是“星系和类星体形成过程的研究”。该光谱仪具有400多重性的能力，波长范围从光学0.9微米到红外1.8微米。我们期望在针对红移为2-5的中早期宇宙的类星体和星系的测试观测计划中获得星系和类星体形成的解的线索。虽然我们用校正镜头和机械平台进行了两次测试观测，但由于主焦点单元的问题以及复杂的摄谱仪系统调整的困难，对遥远类星体和星系的测试观测被推迟了。另一方面，使用FMOS的各种研究计划的讨论超出了预期，对其宽领域和多样性能力抱有很大期望。据此，我们详细报道了FMOS的机械发展情况以及使用该仪器附属于大型望远镜的主要焦点的先进研究计划。特别是，红外光谱仪的冷却能力、整个系统的光学性能、探测器和控制电子设备的特性以及控制软件和档案系统之间的接口被报告为仪器项目，系统地研究了红外光谱仪的性能。作为测试观测计划讨论的结果，还报告了星系形成和暗能量调查项目。全面的观察性研究预计从 2019 财年开始。
