The JWST Advanced Extragalactic Survey JADES

JADES is an infrared imaging and multi-object spectroscopy survey focused on two deep fields: the Hubble Deep Field (GOODS-N) and Hubble Ultra Deep Field (GOODS-S). JADES conducted NIRCam imaging in 8-10 bands, covering about 42 square arcminutes to very deep limits (fainter than 30th magnitude) with an average of about 100 hours of total exposure time, and then another 167 square arcminutes to a typical exposure time of 25 hrs. Coordinated parallels with the MIRI instrument extend this imaging further into the infrared in smaller regions. JADES then performed extensive NIRSpec spectroscopy ...JADES是一项聚焦于两个深空场的红外成像与多目标光谱巡天项目：哈勃深场（GOODS-N）与哈勃超深场（GOODS-S）。该项目利用近红外相机（NIRCam）完成了8至10个波段的成像观测，其中约42平方角分的天区达到极深探测极限（暗于30星等），总平均曝光时长约100小时；另有约167平方角分的天区平均曝光时长为25小时。配合中红外仪器（MIRI）开展的协调平行观测，JADES还在更小尺度的天区范围内，将此类红外成像拓展至更长红外波段。随后，JADES还开展了大规模的近红外光谱仪（NIRSpec）光谱观测工作……
