摘要
欧洲空间局的Euclid任务将提供弱引力透镜和星系成团性巡天，可用于约束标准宇宙学模型及其扩展，并有机会测试超越最小冷暗物质范式的暗物质性质。我们展示了这些巡天组合对描述四个有趣且具有代表性的非最小暗物质模型参数的预测：冷暗物质和温暗物质遗迹的混合；衰变为无质量或有质量遗迹的不稳定暗物质；以及与相对论性遗迹存在微弱相互作用的暗物质。我们使用在专用N体模拟上训练的仿真器，在非线性物质功率谱层面对这些情景进行建模。我们使用模拟的Euclid似然函数来拟合模拟数据，并推断暗物质参数在边缘化其他参数后的误差棒。我们发现，Euclid测光探针（单独或与Planck卫星的宇宙微波背景数据结合）将对这里考虑的四种暗物质模型中的每一种效应都敏感。对于衰变和相互作用的暗物质模型，改进将尤为显著。借助Euclid，某些暗物质参数的界限相比当前限制可以提高多达两个数量级。我们讨论了预测不确定性对不同假设的依赖性：包括测光星系成团性数据、考虑的最小角尺度、重子反馈效应的建模。我们得出结论，Euclid任务将能够以前所未有的灵敏度测量与粒子物理暗区相关的量。这将为高能物理中的模型构建提供重要信息。任何偏离最小冷暗物质范式的迹象都将对宇宙学和粒子物理学产生深远影响。
