Simulating weak lensing on CMB maps

S. Basak, S. Prunet, K. Benabed

摘要:

本文提出了一种快速、任意精度的方法来模拟大尺度结构对宇宙微波背景各向异性和极化场的引力透镜效应。我们证明了该方法的效率和准确性,并展示其依赖于算法参数。

英文摘要:

We present a fast, arbitrarily accurate method to simulate the effect of gravitational lensing of the Cosmic Microwave Background anisotropies and polarization fields by large scale structures. We demonstrate the efficiency and accuracy of the method and exhibit their dependence on the algorithm parameters.
