资源简介:
LSST强引力透镜模拟流程(SLSim)是一个开放源代码工具,用于模拟强引力透镜系统,并考虑了外部汇聚(κext)和剪切(γext)对透镜效应的影响。该数据集通过整合大尺度结构模拟和高分辨率晕渲染,以及非线性校正,来构建外部汇聚和剪切的联合分布,从而准确模拟了视线(LOS)效应。这些数据集和代码为未来的分析提供了工具,以更精确地考虑LOS效应。
LSST Strong Gravitational Lensing Simulation Pipeline (SLSim) is an open-source tool for simulating strong gravitational lensing systems, accounting for the impacts of external convergence (κ_ext) and shear (γ_ext) on lensing effects. This dataset constructs the joint distribution of external convergence and shear by integrating large-scale structure simulations, high-resolution halo rendering, and non-linear corrections, thereby accurately modeling line-of-sight (LOS) effects. These datasets and codes provide tools for future analyses to more precisely account for LOS effects.
