A model Sunyaev-Zel'dovich effect (SZE) sky map
The figure demonstrates simulated deep AMiBA cluster surveys via the Sunyaev-Zel'dovich effect (SZE) based on N-body/Hydrodynamic simulations. The top-left panel shows a model SZ sky map, and the top-right panel shows a realization of SZE (top-left) + CMB
As the AMiBA begins its science mission, we will image clusters via the Sunyaev Zel’dovich effect, where inverse Compton scattering by cluster electrons will cool the background CMB photons at 3mm wavelength. Calculations show that clusters can be detected with the 7-element configuration of the AMiBA. However, the sensitivity will be greatly increased by expanding the array to 13-elements with 1.2m reflectors. The expansion to 13-elements is therefore already underway.
