All Science Programs 2010

Science Program 2010C

The June 2010 Call for Proposals covered the third trimester of 2010. A total of 222 proposals were received. The GBT and the VLA/VLBA Proposal Selection Committees (PSC) met in the second week of August to review the referee rankings and technical reports for all proposals, with the goal of providing a recommended science program to the NRAO Director's Office.

A list of the approved EVLA, VLBA/High Sensitivity Array (HSA), and GBT observing programs for Trimester 2010-C is given below. For each approved program is listed: (a) the PI's last name; (b) the title of the approved proposal, and the total hours allocated for the program, and (d) the type of proposal (Regular or Large). In cases of Large proposals or monitoring projects the time allocated may be over more than one trimester.

Science Program 2010A

The October 2009 call for proposals, covering the first trimester of 2010, included a number of new capabilities. Expanded Very Large Array (EVLA) Early Science is expected to begin in March 2010 following the shutdown of the old VLA correlator and the transfer of hardware to the new EVLA WIDAR correlator. Similarly, the new DiFX software correlator, with increased science capabilities, will go into routine operation for Very Long Baseline Array (VLBA) programs. At the Green Bank Telescope (GBT), the pulsar Spigot and spectrometer system was being retired in favor of the new Green Bank Ultimate Pulsar Processing Instrument (GUPPI) pulsar back end. The first trimester of 2010 also marks an operational milestone with all three of NRAO's current telescopes using dynamic scheduling as the default scheduling mode.

Connect with NRAO

The National Radio Astronomy Observatory and Green Bank Observatory are facilities of the U.S. National Science Foundation operated under cooperative agreement by Associated Universities, Inc.

Founded in 1956, the NRAO provides state-of-the-art radio telescope facilities for use by the international scientific community. NRAO telescopes are open to all astronomers regardless of institutional or national affiliation. Observing time on NRAO telescopes is available on a competitive basis to qualified scientists after evaluation of research proposals on the basis of scientific merit, the capability of the instruments to do the work, and the availability of the telescope during the requested time. NRAO also provides both formal and informal programs in education and public outreach for teachers, students, the general public, and the media.

The National Science Foundation (NSF) is an independent federal agency created by Congress in 1950 "to promote the progress of science; to advance the national health, prosperity, and welfare; to secure the national defense..."

AUI collaborates with the scientific community and research sponsors to plan, build, and operate cutting-edge facilities. We cultivate excellence, deliver value, enhance education, and engage the public.
