论文摘要
我们提出了SMACS J0723.3 $ - $ 7327字段（“ Webb的第一个深场”）的光谱红移目录，该目录从JWST/NIRISS GRISM光谱中获得，并补充了JWST/NIRSPEC和VLT/MUSE REDSHIFTS。该目录总共包含190个带有安全光谱红移的来源，其中包括156个Niriss Grism红移，其中123个用于以前未知的红移。这些新的Grism红移具有两个或多个光谱特征（64个来源），或具有单个光谱特征，其身份从对象的9频段光度光度红移（59个来源）中固定。这些与17个NIRSPEC和48个Muse红移相辅相成，其中包括这项工作中确定的6种新的NIRSPEC红移。除了$ z _ {\ rm cl} = 0.39 $集群星系红移（我们提供$ \ sim $ \ sim $ \ sim 40 $ 40新的Niriss吸收线红移），我们还发现了三个较高的红色速度处于较高的红色速度，$ z = 1.1 $ z = 1.1 $，$ z = 1.4 $，$ z = 2.0 n. VLT/MUSE数据。本文描述了我们的光谱红移样品的特征以及我们采用的方法。我们的红移目录可通过https://niriss.github.io/smacs0723提供给社区。
We present a spectroscopic redshift catalogue of the SMACS J0723.3$-$7327 field ("Webb's First Deep Field") obtained from JWST/NIRISS grism spectroscopy and supplemented with JWST/NIRSpec and VLT/MUSE redshifts. The catalogue contains a total of 190 sources with secure spectroscopic redshifts, including 156 NIRISS grism redshifts, 123 of which are for sources whose redshifts were previously unknown. These new grism redshifts are secured with two or more spectroscopic features (64 sources), or with a single spectral feature whose identity is secured from the object's nine-band photometric redshift (59 sources). These are complemented with 17 NIRSpec and 48 MUSE redshifts, including six new NIRSpec redshifts identified in this work. In addition to the $z_{\rm cl}=0.39$ cluster galaxy redshifts (for which we provide $\sim$40 new NIRISS absorption-line redshifts), we also find three prominent galaxy overdensities at higher redshifts - at $z=1.1$, $z=1.4$, and $z=2.0$ - that were until now not seen in the JWST/NIRSpec and VLT/MUSE data. The paper describes the characteristics of our spectroscopic redshift sample and the methodology we have employed to obtain it. Our redshift catalogue is made available to the community at https://niriss.github.io/smacs0723.
