In the field of cosmology, this shift is referred to as the SZ effect. "The CMB is strongest in the 30-400 gigahertz range," says Wu. "AMiBA makes its observations at around 90 GHz, or at a wavelength of about 3 millimeters. It is currently the only telescope in the world operating and achieving results at this frequency."
「宇宙微波背景輻射在 30-400GHZ 頻段的訊號較強，而 AMiBA 設定的觀測頻段約為 90GHz、觀測波長約 3 毫米，是目前全世界唯一鎖定此段頻率、且已獲得成果的望遠鏡，」吳俊輝相當有自信地說。
