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,…
Weak Lensing Minima and Peaks: Cosmological Constraints and the Impact of Baryons
William R. Coulton, Jia Liu, Ian G. McCarthy +1
We present a novel statistic to extract cosmological information in weak lensing data: the lensing minima. We also investigate the effect of baryons on the cosmological constraints…
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…
Second Data Release of the Hyper Suprime-Cam Subaru Strategic Program
Hiroaki Aihara, Yusra AlSayyad, Makoto Ando +62
This paper presents the second data release of the Hyper Suprime-Cam Subaru Strategic Program, a wide-field optical imaging survey on the 8.2 meter Subaru Telescope. The release in…
The mass-richness relation of optically-selected clusters from weak gravitational lensing and abundance with Subaru HSC first-year data
Ryoma Murata, Masamune Oguri, Takahiro Nishimichi +6
Constraining the relation between the richness and the halo mass over a wide redshift range for optically-selected clusters is a key ingredient for cluster-related science…
