Over the past three years the Combined Array for Research in Millimeter Astronomy (CARMA) was formed from the merger of two telescope arrays supported by the Division of Astronomical Science's University Radio Observatories (URO) Program, these being 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. With commissioning at the new site now complete, 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 over a wide range of angular scales. When new receivers are installed in 2009, CARMA's sensitivity in the 1 mm band will be an order of magnitude greater than that of the previous arrays. 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. CARMA is a pathfinder for the Atacama Large Millimeter Array (ALMA) and a pipeline for training experts in the field of millimeter interferometry to take full advantage of ALMA's capabilities for US astronomy.

在过去的三年里，毫米天文学研究联合阵列 (CARMA) 是由天文科学部大学射电天文台 (URO) 计划支持的两个望远镜阵列合并而成，其中包括加州理工学院欧文斯谷射电天文台 (OVRO) 的六台 10.4 米直径望远镜阵列和伯克利伊利诺伊州马里兰州协会 (BIMA) 的六台直径 10.4 米的望远镜阵列。 9架直径6.1米的望远镜。随着新站点的调试现已完成，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，将在广泛的角度尺度上提供出色的成像。当2009年安装新的接收器时，CARMA在1毫米波段的灵敏度将比以前的阵列高一个数量级。 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。 CARMA 是阿塔卡马大型毫米波阵列 (ALMA) 的探路者，也是培训毫米干涉测量领域专家的渠道，以充分利用 ALMA 的能力促进美国天文学的发展。
