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…
Empirical test for relativistic kinetic theories based on the Sunyaev-Zel'dovich effect
Sandor M. Molnar, Joseph Godfrey
We propose a new method to determine the electron velocity (EV) distribution function in the intracluster gas (ICG) in clusters of galaxies based on the frequency dependence of the…
Geometric Support for Dark Matter by an Unaligned Einstein Ring in Abell 3827
Mandy C. Chen, Tom Broadhurst, Jeremy Lim +4
The non-detection of dark matter (DM) particles in increasingly stringent laboratory searches has encouraged alternative gravity theories where gravity is sourced only from visible…
The Dynamical State of the Frontier Fields Galaxy Cluster Abell 370
Sandor M. Molnar, Shutaro Ueda, Keiichi Umetsu
We study the dynamics of Abell 370 (A370), a highly massive Hubble Frontier Fields galaxy cluster, using self-consistent three-dimensional N-body/hydrodynamical simulations. Our si…
Gas Density Perturbations in Cool Cores of CLASH Galaxy Clusters
Shutaro Ueda, Yuto Ichinohe, Sandor M. Molnar +2
We present a systematic study of gas density perturbations in cool cores of high-mass galaxy clusters. We select 12 relaxed clusters from the Cluster Lensing And Supernova survey w…
