A Multi-Frequency Bolometer Array for Sunyaev-Zel

摘要 LANGE，A. E. AST-9618798 资金将用于将Sunyaev- Zel'dovich红外实验（SuZIE）的探测器升级为SuZIE II，其中包括更大格式的探测器阵列和额外的频率通道。 这些改进将使SuZIE II达到以下科学目标：（1）测量z 0.1处的特殊速度场，精度约为250公里/秒;（2）测量宇宙微波背景的弧分尺度各向异性，精度为Δ T/T = 2 × 10 ~（-6）;（3）根据选择的星团样本确定哈勃常数的值，以使选择偏差最小化;（4）确定高红移星团的数密度;（5）描述度尺度宇宙微波背景各向异性测量中由于未分辨源而造成的混淆。

Abstract LANGE, A. E. AST-9618798 Funds will be used to upgrade the detector for the Sunyaev- Zel'dovich Infrared Experiment (SuZIE) to SuZIE II which includes a larger format detector array and an additional frequency channel. These modifications are expected to enable SuZIE II to reach scientific goals which include (1) measurement of the peculiar velocity field at z 0.1 with a precision of ~ 250 km/sec; (2) measurement of the arcminute scale anisotropy of the cosmic microwave background with a precision of delta T/T of 2 x 10 exp(-6); (3) determination of a value for the Hubble Constant based on a sample of clusters chosen to minimize selection bias; (4) determination of the number density of high redshift clusters; and (5) characterization of the confusion due to unresolved sources in degree-scale cosmic microwave background anisotropy measurements.
