We present a combined cosmic shear analysis of the modeling of line-of-sight distortions on strongly lensed extended arcs and galaxy shape measurements in the COSMOS field. We develop a framework to predict the covariance of strong lensing and galaxy shape measurements of cosmic shear on the basis of the small scale matter power-spectrum. The weak lensing measurement is performed using data from the COSMOS survey calibrated with a cloning scheme using the Ultra Fast Image Generator UFig[1]. The strong lensing analysis is performed by forward modeling the lensing arcs with a main lensing deflector and external shear components from the same Hubble Space Telescope imaging data set. With a sample of three strong lensing shear measurements we present a 2-sigma detection of the cross-correlation signal between the two complementary measurements of cosmic shear along the identical line of sight. With large samples of lenses available with the next generation ground and space based observatories, the covariance of the signal of the two probes with large samples of lenses allows for systematic checks, cross-calibration of either of the two measurement and the measurement of the small scale shear power-spectrum.

我们对 COSMOS 领域中强透镜扩展弧和星系形状测量的视线失真建模进行了组合宇宙剪切分析。我们开发了一个框架来基于小尺度物质功率谱来预测宇宙剪切的强透镜和星系形状测量的协方差。弱透镜测量是使用来自 COSMOS 调查的数据执行的，这些数据使用超快速图像生成器 UFig[1] 进行了克隆方案校准。通过使用主透镜偏转器和来自同一哈勃太空望远镜的外部剪切分量对透镜弧进行正向建模来执行强透镜分析成像数据集。通过三个强透镜切变测量的样本，我们提出了沿相同视线的宇宙切变的两个互补测量之间的互相关信号的 2-sigma 检测。下一代地面和太空观测站提供大量镜头样本，两个探头与大量镜头样本的信号协方差允许系统检查、两个测量中的任何一个的交叉校准和小样本的测量尺度剪切功率谱。
