Scatter and bias in weak lensing selected clusters
Takashi Hamana, Masamune Oguri, Masato Shirasaki +1
We examine scatter and bias in weak lensing selected clusters, employing both an analytic model of dark matter haloes and numerical mock data of weak lensing cluster surveys. We pa…

Probing Primordial Non-Gaussianity with Weak Lensing Minkowski Functionals
Masato Shirasaki, Naoki Yoshida, Takashi Hamana +1
We study the cosmological information contained in the Minkowski Functionals (MFs) of weak gravitational lensing convergence maps. We show that the MFs provide strong constraints o…
