Compliance in Proposal Submission

Only proposals that are submitted via the online PST, that comply with the technical constraints and restrictions described in the Call for Proposals, that conform to the policies stated in this document, and that are received before the submission deadline will be considered. The Observatory reserves the right to reject proposals that do not adhere to the policies in this document.

For semester proposals, the proposal deadline is strictly enforced: no modifications to the proposal can be made by the author after the close of the call. If before the proposal deadline, it is possible to withdrawal a proposal and submit a new version (see Section 3.4.3). Requests to the Helpdesk for modifications to the proposal after the deadline will not be considered. Such requests include, but are not limited to, modifying the author list, the contents of the proposal, and modifying the requested items, such as source coordinates, requested time, or facility resources. Users should not submit duplicate proposals during a single Call for Proposals with the intention of acquiring a more favorable review.

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.
