I am primarily involved with IAA's radio interferometry projects. My work includes mainly characterization of the signal path, data processing and calibration, pipeline, and also producing science results. Past and current projects and their respective science goals are listed briefly below: Past projects [AMiBA]: AMiBA is a compact interferometer array, operating at 3mm wavelength, located in Hawaii. It studies the hot plasma of galaxy clusters through their Sunyaev-Zeldovich effect (SZE), which is a spectral perturbation to the CMB radiation. Together with X-ray and lensing studies, the work helps constrain the growth of the galaxy clusters as well as the underlying cosmology. [AIM-CO]: The AMiBA system has been transformed to study the 3D distribution of molecular gas at redshifts: 0.2, 1.4, 2.7, ... etc. We map the aggregate CO(1-0) emission of galaxies in given observational volumes. Current project: [BURSTT]: BURSTT is building several aperture arrays in and around Taiwan to detect and monitor fast transient events like FRBs and Pulsars, at 400--800MHz. Using VLBI technique and hundreds of km baselines, the FRBs can be localized to their host galaxies for timely follow-up in order to further understand the environment and progenitor of such a phenomenon.
