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.

在该研究项目中，我们开发了一种名为“ FMO”的新型光谱仪，用于在Subaru望远镜上安装纤维多对象光谱仪，该光谱仪对广场观测的重点是主要的重点。这项研究的目的是“研究星系和类星体的形成过程”，如该项目的标题所示。光谱仪具有400多种功能，波长范围从光学0.9微米到红外1.8微米。我们希望在测试观测计划中，以2-5的红移为目标的类星体和星系，以定位的类星体和星系为目标。尽管我们用校正镜和机械阶段进行了两次测试观察，但针对远距离类星体和星系的测试观察结果被Prime-Octocus单元上的问题以及复杂光谱仪系统调整的困难延迟了。另一方面，对使用FMO的各种研究计划的讨论超出了预期的范围，并以其广阔和多样性的能力非常期望。因此，我们使用此工具详细地报告了FMO的机械开发以及与大型望远镜的主要重点相关的高级研究计划。尤其是，据报道，红外光谱仪的冷却能力，整个系统的光学性能，探测器和控制电子的特征以及控制软件与档案系统之间的接口作为仪器项目，对银河系组的系统研究以及黑暗能源的调查项目的调查项目也是由于测试观察计划的讨论而报道了。全面的观察性研究预计是H19财政年度。
