摘要：欧洲空间局（ESA）的欧几里得空间望远镜设计用于在天空的大范围内提供对弱引力透镜畸变的敏感和精确测量。在这里，我们介绍了早期欧几里得观测数据中围绕大质量星系团阿贝尔2390区域的弱引力透镜分析，这是欧几里得早期发布观测计划的一部分。我们使用三种独立算法（LensMC、KSB+ 和 SourceXtractor++）进行星系形状测量。结合欧几里得和斯巴鲁/超普里姆-Cam的多波段光度数据，我们估计光度红移，以优先选择来自分层红移区间的背景源，并使用自组织映射方法和宇宙演化调查（COSMOS）的数据校准红移分布。我们量化了残余的星系团成员污染，并通过光度红移和亮度的分箱，利用源密度分布进行校正，包括对源遮挡和放大效应的校正。我们重建了星系团的质量分布，并将不同分层红移区间的切向归一化剪切轮廓与球形Navarro--Frenk--White模型预测联合拟合，以限制星系团质量，发现三种形状目录的结果一致，并与先前的测量结果良好一致。作为一项重要的验证测试，我们将这些联合约束与针对不同分层红移区间的单独质量测量进行比较，发现良好的一致性。在一篇配套论文中提供了对星系团性质的更详细约束，该论文还结合了强透镜测量。我们的分析首次展示了欧几里得在分层弱透镜测量方面的卓越能力。

摘要： The Euclid space telescope of the European Space Agency (ESA) is designed to provide sensitive and accurate measurements of weak gravitational lensing distortions over wide areas on the sky. Here we present a weak gravitational lensing analysis of early Euclid observations obtained for the field around the massive galaxy cluster Abell 2390 as part of the Euclid Early Release Observations programme. We conduct galaxy shape measurements using three independent algorithms (LensMC, KSB+, and SourceXtractor++). Incorporating multi-band photometry from Euclid and Subaru/Suprime-Cam, we estimate photometric redshifts to preferentially select background sources from tomographic redshift bins, for which we calibrate the redshift distributions using the self-organising map approach and data from the Cosmic Evolution Survey (COSMOS). We quantify the residual cluster member contamination and correct for it in bins of photometric redshift and magnitude using their source density profiles, including corrections for source obscuration and magnification. We reconstruct the cluster mass distribution and jointly fit the tangential reduced shear profiles of the different tomographic bins with spherical Navarro--Frenk--White profile predictions to constrain the cluster mass, finding consistent results for the three shape catalogues and good agreement with earlier measurements. As an important validation test we compare these joint constraints to mass measurements obtained individually for the different tomographic bins, finding good consistency. More detailed constraints on the cluster properties are presented in a companion paper that additionally incorporates strong lensing measurements. Our analysis provides a first demonstration of the outstanding capabilities of Euclid for tomographic weak lensing measurements.
