摘要:

我们介绍宇宙演化早期发布科学(Cosmic Evolution Early Release Science,CEERS)巡天,这是一项时长77.2小时的主任酌情时间早期发布科学计划。CEERS利用JWST仪器套件开展协调、重叠的并行观测,展示、测试并验证高效的河外巡天,观测包括NIRCam和MIRI成像、NIRSpec低分辨率(R~100)和中分辨率(R~1000)光谱,以及NIRCam无缝棱栅(R~1500)光谱。CEERS以哈勃空间望远镜观测过的Extended Groth Strip(EGS)天区为目标,并得到丰富多波段数据的支持。CEERS促进了JWST河外核心科学驱动中“第一缕光”和“星系组装”两方面的即时社区科学,包括:1)在约90角分²的NIRCam成像中发现并表征z >~ 10的大样本星系,约束其丰度和物理性质;2)获得超过1000个星系的深光谱,其中包括数十个位于6<z<10的星系,从而能够测量红移,并通过谱线诊断约束恒星形成和黑洞增长的物理条件;3)定量刻画z>3时首批核球、棒和盘结构;以及4)利用MIRI表征星系中红外辐射,以研究z~1-3时被尘埃遮蔽的恒星形成和超大质量黑洞增长。作为面向社区的遗产产品,CEERS团队已提供若干次数据发布,并附有关于数据处理流程的详细说明和帮助实现可复现性的notebooks。除巡天概览和数据质量外,我们还给出使用CEERS数据前两年的科学亮点。

英文摘要:

We present the Cosmic Evolution Early Release Science (CEERS) Survey, a 77.2 hour Director's Discretionary Early Release Science Program. CEERS demonstrates, tests, and validates efficient extragalactic surveys using coordinated, overlapping parallel observations with the JWST instrument suite, including NIRCam and MIRI imaging, NIRSpec low (R~100) and medium (R~1000) resolution spectroscopy, and NIRCam slitless grism (R~1500) spectroscopy. CEERS targets the Hubble Space Telescope-observed region of the Extended Groth Strip (EGS) field, supported by a rich set of multiwavelength data. CEERS facilitated immediate community science in both of the extragalactic core JWST science drivers ``First Light" and ``Galaxy Assembly," including: 1) The discovery and characterization of large samples of galaxies at z >~ 10 from ~90 arcmin^2 of NIRCam imaging, constraining their abundance and physical nature; 2) Deep spectra of >1000 galaxies, including dozens of galaxies at 6<z<10, enabling redshift measurements and constraints on the physical conditions of star-formation and black hole growth via line diagnostics; 3) Quantifying the first bulge, bar and disk structures at z>3; and 4) Characterizing galaxy mid-IR emission with MIRI to study dust-obscured star-formation and supermassive black hole growth at z~1-3. As a legacy product for the community, the CEERS team has provided several data releases, accompanied by detailed notes on the data reduction procedures and notebooks to aid in reproducibility. In addition to an overview of the survey and quality of the data, we provide science highlights from the first two years with CEERS data.
