Cosmic shear full nulling: sorting out dynamics, geometry and systematics
Francis Bernardeau, Takahiro Nishimichi, Atsushi Taruya
An explicit full nulling scheme for cosmic shear observations is presented. It makes possible the construction of shear maps from extended source distributions for which the lens d…
Simultaneous constraints on the growth of structure and cosmic expansion from the multipole power spectra of the SDSS DR7 LRG sample
Akira Oka, Shun Saito, Takahiro Nishimichi +2
The anisotropic galaxy clustering on large scales provides us with a unique opportunity to probe into the gravity theory through the redshift-space distortions (RSDs) and the Alcoc…
Simulating the Anisotropic Clustering of Luminous Red Galaxies with Subhalos: A Direct Confrontation with Observation and Cosmological Implications
Takahiro Nishimichi, Akira Oka
We model the apparent clustering anisotropy of Luminous Red Galaxies (LRGs) in the Sloan Digital Sky Survey using subhalos identified in cosmological -body simulations. We first…
On the Systematic Errors of Cosmological-Scale Gravity Tests using Redshift Space Distortion: Non-linear Effects and the Halo Bias
Takashi Ishikawa, Tomonori Totani, Takahiro Nishimichi +3
Redshift space distortion (RSD) observed in galaxy redshift surveys is a powerful tool to test gravity theories on cosmological scales, but the systematic uncertainties must carefu…
Modeling the Phase-Space Distribution around Massive Halos
Tsz Yan Lam, Fabian Schmidt, Takahiro Nishimichi +1
The comparison between dynamical mass and lensing mass provides a targeted test for a wide range of modified gravity models. In our previous paper we showed, through numerical simu…
Matter power spectrum from a Lagrangian-space regularization of perturbation theory
Patrick Valageas, Takahiro Nishimichi, Atsushi Taruya
We present a new approach to computing the matter density power spectrum, from large linear scales to small highly nonlinear scales. Instead of explicitly computing a partial serie…
