Radio Relics Tracing the Projected Mass Distribution in CIZA J2242.8+5301
Nobuhiro Okabe, Hiroki Akamatsu, Jun Kakuwa +4
We present a weak-lensing analysis for the merging galaxy cluster, CIZA J2242.8+5301, hosting double radio relics, using three-band Subaru/Suprime-Cam imaging (). Since the…
LoCuSS: Exploring the selection of faint blue background galaxies for cluster weak-lensing
Felicia Ziparo, Graham P. Smith, Nobuhiro Okabe +3
Cosmological constraints from galaxy clusters rely on accurate measurements of the mass and internal structure of clusters. An important source of systematic uncertainty in cluster…
LoCuSS: Weak-lensing mass calibration of galaxy clusters
Nobuhiro Okabe, Graham P. Smith
We present weak-lensing mass measurements of 50 X-ray luminous galaxy clusters at , based on uniform high quality observations with Suprime-Cam mounted on the 8.2-…
Frontier Fields: Subaru Weak-Lensing Analysis of the Merging Galaxy Cluster A2744
Elinor Medezinski, Keiichi Umetsu, Nobuhiro Okabe +5
We present a weak-lensing analysis of the merging {\em Frontier Fields} (FF) cluster Abell~2744 using new Subaru/Suprime-Cam imaging. The wide-field lensing mass distribution revea…
Suzaku observations of subhalos in the Coma cluster
Toru Sasaki, Kyoko Matsushita, Kosuke Sato +1
We observed three massive subhalos in the Coma cluster with {\it Suzaku}. These subhalos, labeled "ID 1", "ID 2", and "ID 32", were detected with a weak-lensing survey using the Su…
Detection of universality of dark matter profile from Subaru weak lensing measurements of 50 massive clusters
Hiroko Niikura, Masahiro Takada, Nobuhiro Okabe +2
We develop a novel method of measuring the lensing distortion profiles of clusters with stacking the scaled amplitudes of background galaxy ellipticities as a function of the scale…
