An azimuthally resolved study of sloshing cold fronts in three nearby galaxy clusters
I-Hsuan Li, Shutaro Ueda, I-Non Chiu +1
We present a detailed analysis of sloshing cold fronts in a sample of three nearby galaxy clusters (Abell 496, Abell 2029, and Abell 1644) observed with the Chandra X-ray Observato…
XRISM-Subaru views of Abell 754: an off-axis, near-line-of-sight merging cluster
Nobuhiro Okabe, Yuki Omiya, Kazuhiro Nakazawa +4
We report a weak-lensing (WL) mass measurement for the merging cluster Abell 754 and impose constraints on the merger trajectory. The trajectory analysis adopts a two-body model wi…
The relation between the cool-core radius and the host galaxy clusters: thermodynamic properties and cluster mass
FanLam Ng, Shutaro Ueda
We present a detailed study of cool-core systems in a sample of four galaxy clusters (RXCJ1504.1-0248, A3112, A4059, and A478) using archival X-ray data from the Chandra X-ray Obse…
Galaxy clusters at z~1 imaged by ALMA with the Sunyaev-Zel'dovich effect
T. Kitayama, S. Ueda, N. Okabe +15
We present high angular-resolution measurements of the thermal Sunyaev-Zel'dovich effect (SZE) toward two galaxy clusters, RCS J2319+0038 at z=0.9 and HSC J0947-0119 at z=1.1, by t…
Line-of-sight Elongation and Hydrostatic Mass Bias of the Frontier Fields Galaxy Cluster Abell 370
Keiichi Umetsu, Shutaro Ueda, Bau-Ching Hsieh +6
We present a detailed weak-lensing and X-ray study of the Frontier Fields galaxy cluster Abell 370, one of the most massive known lenses on the sky, using wide-field BRz Subaru/Spr…
Systematic Perturbations of the Thermodynamic Properties in Cool Cores of HIFLUGCS Galaxy Clusters
Shutaro Ueda, Keiichi Umetsu, FanLam Ng +3
We present an ensemble X-ray analysis of systematic perturbations in the central hot gas properties for a sample of 28 nearby strong cool-core systems selected from the HIghest X-r…
