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…
A Bayesian Hierarchical Approach to Galaxy-Galaxy Lensing
Alessandro Sonnenfeld, Alexie Leauthaud
We present a Bayesian hierarchical inference formalism to study the relation between the properties of dark matter halos and those of their central galaxies using weak gravitationa…
First results on the cluster galaxy population from the Subaru Hyper Suprime-Cam survey. II. Faint end color-magnitude diagrams and radial profiles of red and blue galaxies at
Atsushi J. Nishizawa, Masamue Oguri, Taira Oogi +16
We present a statistical study of the redshift evolution of the cluster galaxy population over a wide redshift range from 0.1 to 1.1, using optically-selected CAMIRA cl…
Two- and three-dimensional wide-field weak lensing mass maps from the Hyper Suprime-Cam Subaru Strategic Program S16A data
Masamune Oguri, Satoshi Miyazaki, Chiaki Hikage +12
We present wide-field (167 deg) weak lensing mass maps from the Hyper Supreme-Cam Subaru Strategic Program (HSC-SSP). We compare these weak lensing based dark matter maps with…
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…
Multiwavelength study of X-ray Luminous Clusters in the Hyper Suprime-Cam Subaru Strategic Program S16A field
Keita Miyaoka, Nobuhiro Okabe, Takao Kitaguchi +34
We present a joint X-ray, optical and weak-lensing analysis for X-ray luminous galaxy clusters selected from the MCXC (Meta-Catalog of X-Ray Detected Clusters of Galaxies) cluster…
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…
Stellar-to-halo mass relation of cluster galaxies
Anna Niemiec, Eric Jullo, Marceau Limousin +12
In the hierarchical formation model, galaxy clusters grow by accretion of smaller groups or isolated galaxies. During the infall into the centre of a cluster, the properties of acc…
Testing redMaPPer centring probabilities using galaxy clustering and galaxy-galaxy lensing
Chiaki Hikage, Rachel Mandelbaum, Alexie Leauthaud +2
Galaxy cluster centring is a key issue for precision cosmology studies using galaxy surveys. Mis-identification of central galaxies causes systematics in various studies such as cl…
An optically-selected cluster catalog at redshift 0.1<z<1.1 from the Hyper Suprime-Cam Subaru Strategic Program S16A data
Masamune Oguri, Yen-Ting Lin, Sheng-Chieh Lin +22
We present an optically-selected cluster catalog from the Hyper Suprime-Cam (HSC) Subaru Strategic Program. The HSC images are sufficiently deep to detect cluster member galaxies d…
