摘要
欧洲空间局的Euclid任务是即将到来的大规模宇宙学巡天之一，将以前所未有的精度绘制宇宙中的大尺度结构。SGS管道的开发和验证需要最先进的模拟，具有高水平的复杂性和准确性，包括以前未考虑的微妙仪器特征以及用于大规模生产预期Euclid数据产品的更快算法。在本文中，我们介绍了Euclid SGS模拟框架，该框架应用于名为科学挑战8的大规模端到端模拟练习。我们的模拟管道能够快速生成详细的图像模拟，用于在资格认证阶段构建和验证Euclid任务，并将在运行期间作为参考。我们的端到端模拟框架从生成大型宇宙学N体与模拟星系目录开始。我们分别对Euclid广域巡天（覆盖165平方度）和Euclid深场巡天（1平方度）进行了I_E=26和28星等的星系选择。我们构建了包含类似银河系恒星（H<26）的真实恒星密度目录。利用Euclid仪器和航天器的最新仪器模型以及类似Euclid的观测序列，我们高保真地模拟了Euclid卫星在整个任务寿命期间的成像。我们展示了SC8数据集，包括重叠的可见光和近红外Euclid广域巡天和Euclid深场巡天成像以及低分辨率光谱，以及地面数据。这个广泛的数据集能够对整个地面段数据缩减和科学分析管道以及Euclid任务基础设施进行端到端测试，为未来的科学和技术发展及改进铺平道路。
