Call for Semester 2014a Observing Proposals

Deadline: 14 January 2014

CARMA, the Combined Array for Research in Millimeter-wave Astronomy, is accepting observing proposals for its 2014a semester, which will extend from 25 February 2014 to 18 August 2014. All 23 antennas are equipped with receivers for the 3mm (85-115 GHz) and 1cm (27-36 GHz) wavelength bands. The 15 largest antennas are equipped with dual-polarization receivers for 1mm wavelengths (210-265 GHz). CARMA typically operates either as a 23-element array or as independent subarrays of 15 antennas and 8 antennas.

The 23-element and 15-element arrays will be available in the E, D, and C configurations. The approximate resolutions of these configurations are 4" (E), 2.5" (D), and 1.0" (C) at 220 GHz, 11" (E), 5.5" (D), and 2.2" (C) at 100 GHz, and 30" (E), 15" (D), and 6" (C) at 35 GHz. The 8-element array will be in configurations optimized to provide high brightness sensitivity of extended objects (at resolutions of 120" at 35 GHz and 45" at 85 GHz), such as observations of the Sunyaev-Zel'dovich effect, for targets at high (SH) and low (SL) declinations.

CARMA comprises 23 antennas operating in the Inyo Mountains of California at an elevation of 2200 meters. CARMA is operated by the California Institute of Technology, and the Universities of California (Berkeley), Illinois, Maryland, and Chicago, under a cooperative agreement with the University Radio Observatories program of the National Science Foundation. Approximately 30% of the awarded time will be given to PIs outside the partner universities.

Proposals should be submitted using the electronic form at: For help with submitting proposals and the proposal system, please email Detailed information, including tools to assist you in preparing proposals, is available at If you require help in understanding CARMA instrument capabilities, please contact the CARMA Help Desk.

The deadline for submitting proposals is 23:00 GMT (17:00 CST) on 14 January 2014a.
