LoCuSS: Testing hydrostatic equilibrium in galaxy clusters
G. P. Smith, P. Mazzotta, N. Okabe +17
We test the assumption of hydrostatic equilibrium in an X-ray luminosity selected sample of 50 galaxy clusters at from the Local Cluster Substructure Survey (LoCuSS).…
Central Mass Profiles of the Nearby Cool-core Galaxy Clusters Hydra A and A478
N. Okabe, K. Umetsu, T. Tamura +14
We perform a weak-lensing study of the nearby cool-core galaxy clusters, Hydra A () and A478 (), of which brightest cluster galaxies (BCGs) host powerful activi…
Universal Profiles of the Intracluster Medium from Suzaku X-Ray and Subaru Weak Lensing Obesrvations
N. Okabe, K. Umetsu, T. Tamura +16
We conduct a joint X-ray and weak-lensing study of four relaxed galaxy clusters (Hydra A, A478, A1689 and A1835) observed by both Suzaku and Subaru out to virial radii, with an aim…
LoCuSS: The Mass Density Profile of Massive Galaxy Clusters at z=0.2
Nobuhiro Okabe, Graham P. Smith, Keiichi Umetsu +2
We present a stacked weak-lensing analysis of an approximately mass-selected sample of 50 galaxy clusters at 0.15<z<0.3, based on observations with Suprime-Cam on the Subaru Telesc…
LoCuSS: Calibrating Mass-Observable Scaling Relations for Cluster Cosmology with Subaru Weak Lensing Observations
Nobuhiro Okabe, Yu-Ying Zhang, Alexis Finoguenov +4
We present a joint weak-lensing/X-ray study of galaxy cluster mass-observable scaling relations, motivated by the critical importance of accurate calibration of mass proxies for fu…
Distance-Redshift Relation in a Realistic Inhomogeneous Universe
Tomohiro Okamura, Toshifumi Futamase
We investigate the distance-redshift relation in a realistic inhomogeneous universe where the mass distribution is described by the mass function of Sheth and Tormen. It is found t…
