ABSTRACTThe Combined Array for Millimeter Astronomy (CARMA) is in the process of merging at a new site two existing telescope arrays supported by the Division of Astronomical Sciences University Radio Observatories (URO) Program. These are Caltech's Owens Valley Radio Observatory (OVRO) array of six 10.4-meter-diameter telescopes, and the Berkeley Illinois Maryland Association (BIMA) array of nine 6.1-meter-diameter telescopes. CARMA will achieve resolutions as high as 0.2 arcseconds at a wavelength of 1mm and, due to its heterogeneous combination of telescope diameters, will provide excellent imaging on all angular scales. CARMA's sensitivity in the 1 mm band will be an order of magnitude greater than that of the existing arrays due to the lower atmospheric attenuation of the new site, and the merged array's greater collecting area, improved receivers and spectrometer, and adaptive atmospheric phase correction. The new science enabled by CARMA covers a broad range of astronomical topics, including star formation and molecular clouds, studies of external galaxies, and the investigation of solar system objects.

摘要毫米天文学组合阵列（CARMA）正在新地点合并由天文科学大学射电天文台（URO）计划支持的两个现有望远镜阵列。 这些是加州理工学院欧文斯谷射电天文台 (OVRO) 阵列的六台直径 10.4 米的望远镜，以及伯克利伊利诺伊州马里兰州协会 (BIMA) 阵列的九台直径 6.1 米的望远镜。 CARMA 将在 1 毫米波长下实现高达 0.2 角秒的分辨率，并且由于其望远镜直径的异构组合，将在所有角度尺度上提供出色的成像。 由于新站点的大气衰减较低，合并后的阵列具有更大的收集面积、改进的接收器和光谱仪以及自适应大气相位校正，CARMA在1毫米波段的灵敏度将比现有阵列高一个数量级。 CARMA 所支持的新科学涵盖了广泛的天文学主题，包括恒星形成和分子云、外部星系的研究以及太阳系物体的调查。
