The systematic survey for distant galaxies with Subaru telescope

本文的研究成果总结如下：1) FOCAS多目标光谱学我们已经完成了斯巴鲁光学成像和光谱观测仪器FOCAS的调试运行。我们还进行了一些改进、优化和性能验证。特别是建立了一次产生大量光谱的多缝光谱观测序列。2)斯巴鲁深场光学多色跟踪成像。在第一年，我们使用CISCO对2‘×2’区域进行了K'=24的近红外成像调查，该区域被称为斯巴鲁深场。在第二年，我们用FOCAS进行了B， R和I成像。现在我们有这个领域的5个波段成像数据。我们现在将推导出一些统计数据，比如在这个领域中探测到的星系的光度红移。根据这些统计数据，我们将确定光谱学的目标。

Achievements of our research are summarized as follows ;1) Multi-Object Spectroscopy with FOCASWe have finished the commissioning run of FOCAS which is the Subaru observational instruments for optical imaging and spectroscopy. We have also carried out several improvements, optimizations and performance verifications. Especially, Observational sequence for the Multi-slit spectroscopy which yields a lot of spectra at once has established.2) The optical multi-color following up imaging for Subaru Deep Field.On the first year, we have carried out a near-infrared imaging survey down to K'=24 with CISCO for the 2'×2' region, which is called as a Subaru Deep Field. On the second year, we have taken a B, R, and I imaging with FOCAS.Now we have 5 bands imaging data for this field. We are now going to derive several statistics such as photometric redshifts of detected galaxies in this field. Based on this statistics we will determine the targets for spectroscopy.
