We consider the effects of weak gravitational lensing on observations of 196 spectroscopically confirmed Type Ia Supernovae (SNe Ia) from years 1 to 3 of the Dark Energy Survey (DES). We simultaneously measure both the angular correlation function and the non-Gaussian skewness caused by weak lensing. This approach has the advantage of being insensitive to the intrinsic dispersion of SNe Ia magnitudes. We model the amplitude of both effects as a function of σ_8, and find σ_8 =1.2|$^{+0.9}_{-0.8}$|⁠. We also apply our method to a subsample of 488 SNe from the Joint Light-curve Analysis (JLA; chosen to match the redshift range we use for this work), and find σ_8 =0.8|$^{+1.1}_{-0.7}$|⁠. The comparable uncertainty in σ_8 between DES–SN and the larger number of SNe from JLA highlights the benefits of homogeneity of the DES–SN sample, and improvements in the calibration and data analysis.

暗能量调查中 Ia 型超新星的弱透镜效应

我们考虑了弱引力透镜对暗能量巡天 (DES) 的第 1 年至第 3 年的 196 颗光谱确认的 Ia 型超新星 (SNe Ia) 观测的影响。我们同时测量角相关函数和弱透镜引起的非高斯偏度。这种方法的优点是对 SNe Ia 震级的固有色散不敏感。我们将两种效应的幅度建模为 σ_8 的函数，并发现 σ_8 =1.2|$^{+0.9}_{-0.8}$|⁠。我们还将我们的方法应用于联合光曲线分析（JLA；选择匹配我们用于这项工作的红移范围）的 488 SNe 子样本，并发现 σ_8 =0.8|$^{+1.1}_{-0.7 }$|⁠。DES-SN 和来自 JLA 的大量 SNe 之间 σ_8 的可比不确定性突出了 DES-SN 样本同质性的好处，
