Joint Proposal Opportunities

The NRAO has agreements with several observatories for Joint proposals where telescope time on Associated Universities Inc. North American (AUI/NA) facilities may be granted by these external telescope time allocation committees (TACs).  Reciprocal agreements exist where the NRAO TAC may grant time on these external facilities.   The table below list these facilities, together with the maximum time that may be allocated by either TAC and a link to the memorandum of understanding (MoU).

ALMA

 50 hours 5% Currently the joint agreement is only for the VLA.  ALMA MoU.
JWST 50 hours 5% JWST MoU.
HST 30 orbits 3% There is no HST MoU.
Swift 300 ksec 5% Swift MoU.
Chandra 120 ksec 3% Chandra MoU.
XMM-Newton 150 ksec 3% XMM-Newton MoU.
NICER 250 ksec 5% NICER MoU.
Fermi N/A 5% There is no reciprocal agreement since Fermi primarily observes in sky-survey mode.  Fermi Mou.

 

 

For joint ALMA-VLA proposals there are constraints on the allowed array configurations.  The table below specifies the allowed VLA and ALMA array configurations when submitting proposals through the VLA (semesters) and ALMA (cycles).

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.
