Introduction

Overview

The Combined Array for Research in Millimeter-wave Astronomy (CARMA) is the merger of two university-based millimeter arrays -- the Owens Valley Radio Observatory (OVRO) millimeter array and the Berkeley-Illinois-Maryland Association (BIMA) millmeter array -- to form a powerful astronomical tool for the new millennium. At a new high-altitude site in eastern California, CARMA will provide unparalleled sensitivity, broad frequency coverage, sub-arcsecond resolution and wide-field heterogeneous imaging capabilities, along with innovative technologies and educational opportunities. OVRO and BIMA pioneered millimeter-wavelength interferometry over the last two decades, and CARMA will carry on that legacy by opening new windows through which to see the universe and by training the next generation of radio astronomers.

Water vapor in the lower parts of the Earth's atmosphere absorbs and distorts astronomical signals at millimeter wavelengths. By locating the new array at 7200 feet above sea level, these signals are greatly reduced, equivalent to increasing the collecting area of the array by 50-100% without building any new antennas. Once all the antennas from BIMA and OVRO are moved to this high site, CARMA will observe radio emission from molecules and dust throughout our universe. Some of the objects CARMA will observe include nearby starburst galaxies, blue dwarf galaxies, nearby molecular clouds forming clusters of stars, newly-born stars emerging from their present clouds, comets, and the cosmic radiation left-over from the Big Bang. During these observations, CARMA will be operated from a small control building adjacent to the antennas, typically by professional astronomers, university faculty, or students. Minor support and maintenance will be performed at the CARMA high site, while most CARMA operations will be based at OVRO. Further engineering and development will occur at OVRO and the university laboratories.

Funding for the construction and operation of CARMA comes from the National Science Foundation and the consortium universities.
