摘要
星系簇周围的物质分布分布在多个光束上，反映了它们作为大尺度宇宙网节点的位置。光束连接到星系簇的数量，即其连通性，预计会影响星系簇的物理属性。利用欧几里亚快速发布1号（Q1）中的第一个星系目录，我们研究了星系簇的连通性及其与物理属性和星系成员属性之间的相关性。在覆盖约63平方度的三个场中，约220个星系的连通性在0.2<z<0.7的红移范围内进行分析。由于光度红移的不确定性，我们在每个星系红移处的170个亚比例h^{-1}.Mpc厚度的2D投影切片中重建宇宙网骨架，并通过两种不同的光束查找算法对最具质量的星系（）进行连通性测量。我们独立地恢复了质量-连通性关系，与前一次测量一致，表明最具质量的星系在平均情况下连接到更多的宇宙光束，符合层级结构形成模型。此外，我们探讨了连通性与两个星系簇属性（早型星系比例和星系成员Sérsic指数）之间的可能相关性。我们的结果表明，由早型星系构成的星系簇的连通性高于由晚型星系主导的星系簇。这些初步研究凸显了我们利用欧几里亚数据量化宇宙网连通性对星系簇属性影响的能力。
