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.

在本研究项目中，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，该望远镜具有宽视场观测的主要焦点。本研究的目标是“星系和类星体形成过程的研究”，如项目名称所示。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。我们期望通过对红移为2-5的中早期宇宙中的类星体和星系的测试观测，获得星系和类星体形成的线索。虽然我们用校正透镜和机械载物台进行了两次试验观测，但由于主聚焦装置的问题和复杂的光谱仪系统的调整困难，对遥远类星体和星系的试验观测被推迟了。另一方面，使用FMOS的各种研究计划的讨论超过了预期，人们对其宽领域和多重性能力寄予厚望。因此，我们报告的FMOS的机械发展的详细和先进的研究计划，使用这种仪器附加到大望远镜的主焦点。特别是红外光谱仪的冷却能力，整个系统的光学性能，探测器和控制电子学的特性，以及控制软件和存档系统之间的接口作为仪器项目进行了报告，星系形成的系统研究，以及暗能量的调查项目也作为测试观测计划讨论的结果进行了报告。全面的观察性研究预计将于H19财年开始。
