The ultimate goal of this research is to determine the geometric parameters of the Universe by measuring the Fell/MgII emission line ratios of high-redshift quasars, and to understand galaxy evolution by identifying far-infrared sources. We thus intend to execute a southern CCD survey for searching for high-redshift quasars (measuring Fell/MgII) and for accumulating CCD image data (identifying far-infrared sources). In the present research, we have developed the instrument of the southern CCD survey and the model of quasar emission, identified ISO far-infrared sources, and studied the characteristics of the world best observing site in north Chile. The results are given below:・ The control circuit of the CCD camera was replaced, and the first engineering light was successfully taken in 2001 December. The software was updated in February 2002, and the first scientific run is scheduled in late-April, 2002.・ While the said CCD camera was delayed, we have carried out CCD imaging and spectroscopy of ISO far-infrared at KPNO, Subarii, and Keck as well as deep radio imaging with VLA. Up to date, spectra of 100 sources were taken. As of writing, data reduction has completed for 30 sources. One third of them have been identified with ULIRGs (Ultra-Luminous IR Galaxies), and most of them are interacting galaxies.・ Modeling of line transfer in a QSO BLR is vitally important to derive the Fe/Mg abundance from the observed Fell/MgII. To improve such models, we have invited Dr. E. Verner from CUA/NASA. The high quality QSO spectra for modeling were taken at KPNO・ In conjunction with NOAO, we have analyzed weather satellite data for the last 10 years in north Chile, and has identified with candidates for the best sites in the Atacama area. We have built a weather monitor and installed at the site in the Atacama for monitoring weather.

这项研究的最终目的是通过测量高红移类星体的Fell/MgII发射线比率来确定宇宙的几何参数，并通过识别远红外源来了解星系的演化。因此，我们打算进行一项南方电荷耦合器件调查，用于搜索高红移类星体(测量Fell/MgII)和积累电荷耦合器件图像数据(识别远红外源)。在本研究中，我们研制了南方CCD测量仪器和类星体发射模型，确定了ISO远红外源，并研究了智利北部世界最佳观测点的特征。结果如下：·更换了CCD摄像机的控制电路，并于2001年12月成功地拍摄了第一个工程灯。该软件于2002年2月更新，第一次科学运行计划于2002年4月下旬进行。·在上述CCD相机被延迟的情况下，我们已经在KPNO、Suarii和Keck进行了ISO远红外的CCD成像和光谱，以及VLA的深射电成像。到目前为止，已经获得了100个源的光谱。在撰写本文时，已经完成了30个来源的数据缩减。它们中的三分之一已被确定为ULIRGs(超发光IR星系)，其中大多数是相互作用的星系。·对类星体BLR中的线转移进行模拟，对于从观测到的Fell/MgII得到Fe/Mg丰度是至关重要的。为了改进这些模型，我们邀请了加州大学/NASA的E.Verner博士。用于模拟的高质量类星体光谱是在KPNO·与NOAO联合拍摄的，我们分析了智利北部过去10年的气象卫星数据，并确定了阿塔卡马地区最佳地点的候选者。我们已经建造了一个天气监测器，并在阿塔卡马的现场安装了天气监测器。
