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，毫米波天文学研究组合阵列（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的，这两个望远镜阵列是加州理工学院？美国欧文斯谷射电天文台（OVRO）的六个10.4米直径的望远镜阵列，和伯克利伊利诺伊州马里兰州协会（比马）的九个6.1米直径的望远镜阵列。随着新站点的调试工作现已完成，CARMA将在1毫米波长处实现高达0.2角秒的分辨率，并且由于其望远镜直径的异质组合，将在广泛的角度范围内提供出色的成像。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所带来的新科学涵盖了广泛的天文学主题，包括星星形成和分子云，外部星系的研究以及太阳系天体的调查。CARMA是阿塔卡马大型毫米波阵列（阿尔马）的探路者，也是培训毫米波干涉测量领域专家的管道，以充分利用阿尔马的能力为美国天文学服务。
