本文介绍 JWST UNCOVER Treasury 巡天设计，涵盖 Abell 2744 的超深 NIRCam/NIRISS 成像与约500个星系的 NIRSpec 光谱后续，并发布首批处理拼图。

摘要：

本文介绍了再电离纪元之前的超深 NIRSpec 与 NIRCam 观测（UNCOVER）Cycle 1 JWST Treasury 项目的巡天设计，该项目于2022年11月执行了其早期成像部分。UNCOVER 巡天包括对位于 z=0.308、已被充分研究的 Abell 2744 星系团及其周围约45 arcmin²区域进行超深（约29–30 AB）成像，并将于2023年夏季利用 NIRSpec/PRISM 对约500个星系进行极深低分辨率光谱后续观测，且在2024年夏季进行重复访问。我们描述了科学目标、巡天设计、目标选择和计划的数据发布。我们还展示并表征了首个 NIRCam 成像拼图的深度，强调了该视场中已知天体此前无与伦比的、分辨清晰的2–4微米超深成像。UNCOVER 主 NIRCam 拼图在七个滤光片（F115W、F150W、F200W、F277W、F356W、F410M、F444W）中覆盖28.8 arcmin²，并在 NIRISS 并行观测（F115W、F150W、F200W、F356W 和 F444W）中覆盖16.8 arcmin²。为最大限度提高 Treasury 数据集的早期社区利用率，我们公开发布公共 JWST 成像的完整处理后拼图，包括 Abell 2744 星系团上及其周围45 arcmin²的 NIRCam 和17 arcmin²的 NIRISS 拼图，涵盖 Hubble Frontier Field 的主视场和并行视场足迹。

英文摘要：

In this paper we describe the survey design for the Ultradeep NIRSpec and NIRCam ObserVations before the Epoch of Reionization (UNCOVER) Cycle 1 \JWST Treasury program, which executed its early imaging component in November 2022. The UNCOVER survey includes ultradeep ($\sim29-30\mathrm{AB}$) imaging of $\sim$45 arcmin$^2$ on and around the well-studied Abell 2744 galaxy cluster at $z=0.308$ and will follow-up ${\sim}500$ galaxies with extremely deep low-resolution spectroscopy with the NIRSpec/PRISM during the summer of 2023, with repeat visits in summer 2024. We describe the science goals, survey design, target selection, and planned data releases. We also present and characterize the depths of the first NIRCam imaging mosaic, highlighting previously unparalleled resolved and ultradeep 2-4 micron imaging of known objects in the field. The UNCOVER primary NIRCam mosaic spans 28.8 arcmin$^2$ in seven filters (F115W, F150W, F200W, F277W, F356W, F410M, F444W) and 16.8 arcmin$^2$ in our NIRISS parallel (F115W, F150W, F200W, F356W, and F444W). To maximize early community use of the Treasury data set, we publicly release full reduced mosaics of public JWST imaging including 45 arcmin$^2$ NIRCam and 17 arcmin$^2$ NIRISS mosaics on and around the Abell 2744 cluster, including the Hubble Frontier Field primary and parallel footprints.
