The splashback radius of optically selected clusters with Subaru HSC Second Public Data Release
Ryoma Murata, Tomomi Sunayama, Masamune Oguri +4
Recent constraints on the splashback radius around optically selected galaxy clusters from the redMaPPer cluster-finding algorithm in the literature have shown that the observed sp…
The Richness-to-Mass Relation of CAMIRA Galaxy Clusters from Weak-lensing Magnification in the Subaru Hyper Suprime-Cam Survey
I-Non Chiu, Keiichi Umetsu, Ryoma Murata +2
We present a statistical weak-lensing magnification analysis on an optically selected sample of 3029 \texttt{CAMIRA} galaxy clusters with richness at redshift $0.2\leq z <1.…
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…
Dark Quest. I. Fast and Accurate Emulation of Halo Clustering Statistics and Its Application to Galaxy Clustering
Takahiro Nishimichi, Masahiro Takada, Ryuichi Takahashi +8
We perform an ensemble of -body simulations with particles for 101 flat CDM cosmological models sampled based on a maximin-distance Sliced Latin Hypercube Design. By…
Characterization and Photometric Performance of the Hyper Suprime-Cam Software Pipeline
Song Huang, Alexie Leauthaud, Ryoma Murata +9
The Subaru Strategic Program (SSP) is an ambitious multi-band survey using the Hyper Suprime-Cam (HSC) on the Subaru telescope. The Wide layer of the SSP is both wide and deep, rea…
