论文摘要
释放的第一个James Webb空间望远镜（JWST）图像是Galaxy群集SMACSJ0723.3-7327，Z = 0.39的镜头群集显示了JWST只能提供的细节。尽管大部分的重点都集中在远远超出红移的出色镜头星系上，但故事不仅仅是一个镜头群。 Chandra X射线温度图讲述了一个与显着的亚集群合并群集的故事，使集群内培养基（ICM）唤醒。本文使用自适应圆形套筒呈现了SMACSJ0723.3-7327的高富达温度图，并与JWST图像覆盖，显示了合并活动的清晰迹象。随着ICM超过JWST图像的边界，尚未发表低频无线电观察结果，有关该集群的完整故事仍然有待讲述。这个新的X射线温度图揭示了中等距离主动合并群集的新细节。
The first James Webb Space Telescope (JWST) image released was of galaxy cluster SMACSJ0723.3- 7327, a lensing cluster at z=0.39 showing detail only JWST can provide. While the majority of the focus has been on the brilliantly lensed galaxies at redshifts far beyond it, there is more to the story than it being just a lensing cluster. The Chandra X-ray temperature map tells a tale of a merging cluster with a significant subcluster leaving a wake in the intracluster medium (ICM). This paper presents a high fidelity temperature map of SMACSJ0723.3-7327 using adaptive circular binning, overlaid with the JWST image, showing clear signs of merger activity. As the ICM extends well past the boundaries of the JWST imagery, and no low-frequency radio observations are yet published, a fuller story of this cluster remains to be told. This new X-ray temperature map reveals new details of a moderately distant actively merging cluster.
