Fitting the nonlinear matter bispectrum by the Halofit approach
Ryuichi Takahashi, Takahiro Nishimichi, Toshiya Namikawa +5
We provide a new fitting formula of the matter bispectrum in the nonlinear regime calibrated by high-resolution cosmological -body simulations of cold dark matter (CDM,…
Perturbation theory for the redshift-space matter power spectra after reconstruction
Chiaki Hikage, Kazuya Koyama, Ryuichi Takahashi
We derive the one-loop perturbative formula of the redshift-space matter power spectrum after density field reconstruction in the Zeldovich approximation. We find that the reconstr…
The Weak Lensing Bispectrum Induced By Gravity
D. Munshi, T. Namikawa, T. D. Kitching +5
Recent studies have demonstrated that {\em secondary} non-Gaussianity induced by gravity will be detected with a high signal-to-noise (S/N) by future and even by on-going weak lens…
Cross-correlation of the thermal Sunyaev-Zel'dovich effect and weak gravitational lensing: Planck and Subaru Hyper Suprime-Cam first-year data
Ken Osato, Masato Shirasaki, Hironao Miyatake +4
Cross-correlation analysis of the thermal Sunyaev-Zel'dovich (tSZ) effect and weak gravitational lensing (WL) provides a powerful probe of cosmology and astrophysics of the intra-c…
Cosmological information content in redshift-space power spectrum of SDSS-like galaxies in the quasi-nonlinear regime up to Mpc
Yosuke Kobayashi, Takahiro Nishimichi, Masahiro Takada +1
Clustering properties and peculiar velocities of halos in large-scale structure carry a wealth of cosmological information over a wide range of scales from linear to nonlinear scal…
Evidence for the Cross-correlation between Cosmic Microwave Background Polarization Lensing from POLARBEAR and Cosmic Shear from Subaru Hyper Suprime-Cam
Toshiya Namikawa, Yuji Chinone, Hironao Miyatake +72
We present the first measurement of cross-correlation between the lensing potential, reconstructed from cosmic microwave background (CMB) {\it polarization} data, and the cosmic sh…
