Tests of AMiBA Data Integrity
Hiroaki Nishioka, Fu-Cheng Wang, Jiun-Huei Proty Wu +26
We describe methods used to validate data from the Y.T. Lee Array for Microwave Background Anisotropy (AMiBA), an interferometric array designed to measure the Sunyaev-Zel'dovich e…
Dynamical Study of A1689 from Wide-Field VLT/VIMOS Spectroscopy: Mass Profile, Concentration Parameter, and Velocity Anisotropy
Doron Lemze, Tom Broadhurst, Yoel Rephaeli +2
We examine the dynamics structure of the rich cluster A1689, combining VLT/VIMOS spectroscopy with Subaru/Suprime-Cam imaging. The radial velocity distribution of cluste…
The Yuan-Tseh Lee Array for Microwave Background Anisotropy
Paul T. P. Ho, Pablo Altamirano, Chia-Hao Chang +52
The Yuan-Tseh Lee Array for Microwave Background Anisotropy (AMiBA) is the first interferometer dedicated to studying the cosmic microwave background (CMB) radiation at 3mm wavelen…
Mass and Hot Baryons in Massive Galaxy Clusters from Subaru Weak Lensing and AMiBA SZE Observations
Keiichi Umetsu, Mark Birkinshaw, Guo-Chin Liu +30
We present a multiwavelength analysis of a sample of four hot (T_X>8keV) X-ray galaxy clusters (A1689, A2261, A2142, and A2390) using joint AMiBA Sunyaev-Zel'dovich effect (SZE) an…
Comparison of Cluster Lensing Profiles with Lambda CDM Predictions
Tom Broadhurst, Keiichi Umetsu, Elinor Medezinski +2
We derive lens distortion and magnification profiles of four well known clusters observed with Subaru. Each cluster is very well fitted by the general form predicted for Cold Dark…
