Non-negative matrix factorization for self-calibration of photometric redshift scatter in weak lensing surveys
Le Zhang, Yu Yu, Pengjie Zhang
Photo-z error is one of the major sources of systematics degrading the accuracy of weak lensing cosmological inferences. Zhang et al. (2010) proposed a self-calibration method comb…

Fast generation of weak lensing maps by the inverse-Gaussianization method
Yu Yu, Pengjie Zhang, Yipeng Jing
To take full advantage of the unprecedented power of upcoming weak lensing surveys, understanding the noise, such as cosmic variance and geometry/mask effects, is as important as u…
