东京大学阿塔卡马天文台是一个由东京大学天文学研究所推动的项目,目的是在智利北方海拔5,640米的Chajnantor山顶建造一台6.5米的红外优化望远镜。由于高海拔和低水汽含量,在0.9 ~ 2.5μm范围内出现连续窗口,在25μm以上出现新窗口。该站点显示出极低的可降水量为0.5mm(25百分位数),可用夜间的比例超过80%。观测到的中位视宁度为0.69,与世界上主要的天文台相当或更好。在6.5米望远镜之前,安装了一个名为miniTAO的1米探路者望远镜,并于2009年开始观测。它在1.875 μm的Paschen α成像和30μm的中红外观测的成功证实了该站点的潜力。6.5米望远镜目前正处于设计阶段,目前正在建造两个设施仪器,一个是视场为9 '.6的近红外成像仪/多物体摄谱仪,另一个是用于2至38微米观测的中红外成像仪/摄谱仪。
The University of Tokyo Atacama Observatory (TAO) is a project to construct a 6.5m infrared-optimized telescope at the summit of Co. Chajnantor, 5,640 m altitude, in northern Chile, promoted by Institute of Astronomy, University of Tokyo. Thanks to the high altitude and low water vapor, continuous window from 0.9 to 2.5μm as well as new windows at wavelength longer than 25μm appears. The site shows extremely low precipitable water vapor of 0.5mm (25 percentile), and fraction of usable night is more than 80%. Measured median seeing is 0".69, which is comparable or better than major observatories over the world. Prior to the 6.5m telescope, a 1m pathfinder telescope called miniTAO is installed and started observations in 2009. Its successes of Paschen α imaging at 1.875 μm and mid-infrared observations at 30μm confirm promising capabilities of the site. The 6.5m telescope is now at a design phase, and two facility instruments are now being constructed, which are a near-infrared imager/multi-object spectrograph with a field of view of 9'.6 and a mid-infrared imager/spectrograph for observations in 2 to 38μm.
