摘要
我们将暗能量巡天（DES）第一年（Y1）数据的星系弱透镜测量与源自南极望远镜（SPT）和Planck数据的宇宙微波背景（CMB）弱透镜图进行交叉关联，有效重叠面积为1289 deg。利用来自四个源星系红移 bin 的组合测量，我们以的显著性拒绝无透镜假设。当采用角尺度截断时，该显著性降至，这仍是迄今此类最高信噪比的测量。我们在将宇宙学参数固定为基准CDM模型的同时拟合关联函数的幅度，发现。我们还利用关联函数测量约束剪切校准偏差，获得的约束与先前DES分析一致。最后，当在CDM模型下进行宇宙学分析时，我们得到边缘化约束和。这些测量用于一项伴随工作，该工作给出了利用DES、SPT和Planck数据对星系、星系剪切与CMB透镜之间两点函数的联合分析所得到的宇宙学约束。
