摘要
星系形态与形状方向预计与其大尺度环境相关联，因为它们通过从宇宙网吸积物质而生长，并受与其他星系相互作用的制约。从欧几里亚快速数据发布1号（覆盖63.1平方度）的投影中提取宇宙光束，在0.5<z<0.9的红移范围内进行170个亚比例h^{-1}Mpc厚度的切片中进行宇宙光束提取。由于欧几里亚VIS数据的优异分辨率，星系形态被准确检索。分析测量的VIS数据下，质量为的星系在投影宇宙网中的分布，作为形态函数进行分析。具体而言，以Sérsic指数和质量为函数，量化星系形状在大尺度光束中的2D对齐程度。我们发现更致密的星系位于光束脊背附近。固定星系质量时，形态既与密度也与距离大尺度光束相关联。此外，数据集的大规模使我们能够检测到大量早型星系主要轴沿投影宇宙光束方向的偏好对齐信号。总体而言，这些结果展示了我们利用欧几里亚数据进行详细星系环境研究的能力，这将在更高的红移范围和更低的星系质量下扩展至未来的欧几里亚深层调查。
