Lange, Andrew 96-17161 Dr. Lange will use measurements from the Sunyaev- Zel'dovich Infrared Experiment (SuZIE) at the Caltech Submillimeter Observatory to survey a large sample of clusters of galaxies over a two- year period. The goals of the program are to measure the peculiar velocity field of the clusters, to measure the scale anisotropy of the CMB, to determine a value for the Hubble constant based on an unbiased sample of clusters, to determine the number density of high redshift clusters, and to characterize the confusion due to unresolved sources in the CMB anisotropy measurements.

电话：96-17161 兰格博士将使用加州理工学院亚毫米波天文台的苏尼亚耶夫-泽尔多维奇红外实验（SuZIE）的测量结果，在两年的时间里对星系团的大样本进行调查。 该计划的目标是测量星系团特有的速度场，测量CMB的尺度各向异性，确定基于无偏样本的哈勃常数值，确定高红移星系团的数密度，并描述由于CMB各向异性测量中未解决的源造成的混乱。
