An Update on AMiBA

Author(s): Jiun-Huei Proty Wu and AMiBA Team

Presenter: Jiun-Huei Proty Wu (National Taiwan University)

The Y. T. Lee Array for Microwave Background Anisotropy (a.k.a. Array for Microwave Background Anisotropy, AMiBA) is an interferometric experiment designed to study cosmology via the measurement of Cosmic Microwave Background (CMB). With the system expanded to 13 elements of 1.2-m antennae, in the past few years we focused on solutions to hardware problems, such as radio-pointing errors and platform deformation, leading to successful observations of the Sunyaev-Zel’dovich Effects (SZE) for tens of galaxy clusters (0.08 < z < 0.7). These results are analyzed for the study of scaling relationship, baryonic fraction, cluster evolution and properties, Hubble parameter, etc.
