Statistical and Systematic Errors in Measurement of Weak-Lensing Minkowski Functionals: Application to Canada-France-Hawaii Lensing Survey
Masato Shirasaki, Naoki Yoshida
The measurement of cosmic shear using weak gravitational lensing is a challenging task that involves a number of complicated procedures. We study in detail the systematic errors in…
Weighing the Light Gravitino Mass with Weak Lensing Surveys
Ayuki Kamada, Masato Shirasaki, Naoki Yoshida
We explore the discovery potential of light gravitino mass m_{3/2} by combining future cosmology surveys and collider experiments. The former probe the imprint of light gravitinos…
Effect of Mask Regions on Weak Lensing Statistics
Masato Shirasaki, Naoki Yoshida, Takashi Hamana
Sky masking is unavoidable in wide-field weak lensing observations. We study how masks affect the measurement of statistics of matter distribution probed by weak gravitational lens…
