Atacama Large Millimeter/submillimeter Array (ALMA)
ALMA is a partnership of East Asia, Europe, and North America in cooperation with the Republic of Chile. ALMA is funded in East Asia by the National Institutes of Natural Sciences of Japan in cooperation with the Academia Sinica in Taiwan, in Europe by the European Southern Observatory (ESO) and in North America by the U.S. National Science Foundation in cooperation with the National Research Council of Canada and the National Science Council of Taiwan. ALMA construction and operations are led on behalf of East Asia by the National Astronomical Observatory of Japan, on behalf of Europe by ESO and on behalf of North America by the NRAO.
Expanded Very Large Array (EVLA)
The Expanded Very Large Array (EVLA) is a partnership of the United States, Canada, and Mexico. The EVLA is funded in the United States by the National Science Foundation, in Canada by the National Research Council, and in Mexico by the Comisión Nacional de Investigación Científica y Tecnológica (CONICyT).
Green Bank Telescope (GBT)
In partnership with multiple university, college, and industry research groups, the NRAO is working to enable the next quantum leap in GBT science capability by developing next generation camera systems, including conventional feed horn arrays, phased array receivers, and bolometer arrays. Our partners in this development program include: the Univ. of Pennsylvania, National Institute of Standards and Technologies, Univ. of Virginia, Univ. of Calgary, West Virginia Univ., UC-Berkeley, Univ. of Maryland, Univ. of Cincinnati, Brigham Young Univ., Xilinx Inc., Univ. of Massachusetts, California Institute of Technology, Stanford Univ., Jet Propulsion Laboratory, Agnes Scott College, Ramen Research Institute, Cambridge Univ., Rutgers Univ., Univ. of British Columbia, Univ. of Hertfordshire, RadioAstron, and the Univ. of New South Wales.
The CICADA program develops new backends using reconfigurable, off-the-shelf hardware platforms and software tools that enable the rapid design, verification, and deployment of astronomical signal processing systems. This work is an NRAO collaboration with UC-Berkeley, Univ. of Cincinnati, West Virginia Univ., Xilinx Inc., MIT, and others. The program is based on hardware and tools developed by the UC-Berkeley Center for Astronomy Signal Processing and Electronics Research (CASPER) group.
Precision Array to Probe Epoch of Reionization (PAPER)
PAPER is a partnership between the NRAO and scientists at UC-Berkeley, U. Virginia, U. Penn., and Curtin U. in Australia. Graduate students from these institutions have become actively engaged in instrumentation, from the development of electronic systems through astronomical observations and data analysis, while also participating in a highly visible scientific endeavor.
Lunar University Node for Astrophysics Research (LUNAR)
The NRAO is collaborating in the LUNAR program, a successful proposal from the University of Colorado to establish a node of the NASA Lunar Science Institute and develop concepts for performing astrophysics from the Moon. LUNAR science is envisioned to include low frequency cosmology, gravitational physics and lunar structure, and radio heliophysics.
