University of Illinois
at Urbana-Champaign




The University of Illinois at Urbana-Champaign is a founding member of the Combined Array for Research in Millimeter-Wavelength Astronomy consortium (CARMA), comprising the following institutions:

  • California Institute of Technology
  • University of California Berkeley
  • University of Chicago
  • University of Maryland
  • University of Illinois at Urbana-Champaign

The CARMA array was formed by combining the existing Berkeley-Illinois-Maryland Millimeter Array (BIMA) and the Owens Valley Radio Observatory millimeter array (OVRO) at a new high-altitude site at Cedar Flat, near Bishop, CA, producing a combined array with 15 antennas. It is intended that the Sunyaev-Zeldovich Array (SZA) be relocated to the same site in 2008, producing an array of 23 antennas.

UIUC participation in CARMA is via the Laboratory for Astronomical Imaging at the the Department of Astronomy (LAI) and the RAI group at NCSA. The science data flow and data management sub-systems were developed for CARMA by NCSA. All CARMA science and engineering data are transferred to NCSA, which is the sole archive and primary pipeline processing site for the telescope.

The Cedar Flat site before and after construction is shown below.

The CARMA array was dedicated in May 2006, and started open community scientific observing in Jan 2007. The CARMA project is funded by the National Science Foundation and by the participating institutions in the CARMA consortium.
