Toward understanding the anisotropic point spread function of Suprime-Cam and its impact on cosmic shear measurement
Takashi Hamana, Satoshi Miyazaki, Yuki Okura +2
We examined the anisotropic point spread function (PSF) of Suprime-Cam data utilizing dense star field data. We decomposed the PSF ellipticities into three components, the optical…
Next-to-leading resummation of cosmological perturbations via the Lagrangian picture: 2-loop correction in real and redshift spaces
Tomohiro Okamura, Atsushi Taruya, Takahiko Matsubara
We present an improved prediction of the nonlinear perturbation theory (PT) via the Lagrangian picture, which was originally proposed by Matsubara (2008). Based on the relations be…
Magnification effect on the detection of primordial non-Gaussianity from photometric surveys
Toshiya Namikawa, Tomohiro Okamura, Atsushi Taruya
We present forecast results for constraining the primordial non-Gaussianity from photometric surveys through a large-scale enhancement of the galaxy clustering amplitude. In photom…
