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.…
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…
Cosmology from cosmic shear power spectra with Subaru Hyper Suprime-Cam first-year data
Chiaki Hikage, Masamune Oguri, Takashi Hamana +34
We measure cosmic weak lensing shear power spectra with the Subaru Hyper Suprime-Cam (HSC) survey first-year shear catalog covering 137deg of the sky. Thanks to the high effect…
Weak-Lensing Mass Calibration of ACTPol Sunyaev-Zel'dovich Clusters with the Hyper Suprime-Cam Survey
Hironao Miyatake, Nicholas Battaglia, Matt Hilton +57
We present weak-lensing measurements using the first-year data from the Hyper Suprime-Cam Strategic Survey Program on the Subaru telescope for eight galaxy clusters selected throug…
Weak lensing shear calibration with simulations of the HSC survey
Rachel Mandelbaum, François Lanusse, Alexie Leauthaud +8
We present results from a set of simulations designed to constrain the weak lensing shear calibration for the Hyper Suprime-Cam (HSC) survey. These simulations include HSC observin…
Constraints on the mass-richness relation from the abundance and weak lensing of SDSS clusters
Ryoma Murata, Takahiro Nishimichi, Masahiro Takada +5
We constrain the scaling relation between optical richness () and halo mass () for a sample of SDSS redMaPPer galaxy clusters within the context of the {\it Planck} cosmologi…
Source Selection for Cluster Weak Lensing Measurements in the Hyper Suprime-Cam Survey
Elinor Medezinski, Masamune Oguri, Atsushi J. Nishizawa +13
We present optimized source galaxy selection schemes for measuring cluster weak lensing (WL) mass profiles unaffected by cluster member dilution from the Subaru Hyper Suprime-Cam S…
The first-year shear catalog of the Subaru Hyper Suprime-Cam SSP Survey
Rachel Mandelbaum, Hironao Miyatake, Takashi Hamana +28
We present and characterize the catalog of galaxy shape measurements that will be used for cosmological weak lensing measurements in the Wide layer of the first year of the Hyper S…
Robust covariance estimation of galaxy-galaxy weak lensing: validation and limitation of jackknife covariance
Masato Shirasaki, Masahiro Takada, Hironao Miyatake +4
We develop a method to simulate galaxy-galaxy weak lensing by utilizing all-sky, light-cone simulations and their inherent halo catalogs. Using the mock catalog to study the error…
Detection of the Splashback Radius and Halo Assembly bias of Massive Galaxy Clusters
Surhud More, Hironao Miyatake, Masahiro Takada +10
We show that the projected number density profiles of SDSS photometric galaxies around galaxy clusters displays strong evidence for the splashback radius, a sharp halo edge corresp…
