摘要
我们介绍了下一代深场河外探测公开（NGDEEP）巡天，这是一个JWST第一轮 Treasury 深无缝光谱与成像巡天，旨在约束宇宙时标上低质量星系中的反馈机制。NGDEEP以哈勃超深场（HUDF）为目标，利用NIRISS无缝光谱（f~1.2e-18 erg/s/cm^2，5sigma）测量低质量星系在宇宙SFR密度峰值时期（0.5<z<4）的金属丰度与恒星形成率（SFR）。同时，NGDEEP以HUDF-Par2平行场为目标，利用NIRCam（m=30.6-30.9，5sigma）发现红移z>12的星系，约束静止紫外光度函数暗端斜率。NGDEEP与天空中最深的HST ACS光学成像重叠：HUDF中的F435W（m=29.6）与HUDF-Par2中的F814W（m=30），这使其成为首屈一指的HST+JWST深场。作为Treasury巡天，NGDEEP数据立即公开，我们将本着先前深场计划的宗旨快速释放数据产品和星表。本文中我们介绍NGDEEP巡天设计，总结科学目标，并详述NGDEEP归算数据产品公开释放的计划。
