Alerts & Tips for Proposers

Source Lists

LBO requires proposers to specify their source lists in full. This enables the LBO to identify potential conflicts between observing programs and to better understand scheduling pressure on the instruments it operates. It may be the case that the final target list has not been selected at the time a proposal is submitted. In such cases, all potential targets and fields should be listed. The only exceptions to this requirement are for Triggered proposals to observe targets that are unknown a priori. Proposal source lists are not made public by the LBO.

Dissertation Plans

Students planning to use the VLBA for their PhD dissertation must submit a "Plan of Dissertation Research" of no more than 1000 words with their first proposal. This plan must be referred to in later proposals for time allocations relevant to the thesis work described in the plan. It is the responsibility of the student to ensure that the information contained in the plan is up-to-date at the time a given proposal is submitted. By the same token, a proposal for work that is relevant to a student thesis should refer to the plan and clearly state the relevance of the proposal to the plan. At a minimum the plan should contain:

  1. An overview of the research program
  2. The thesis timeline, including the expected date of completion
  3. An estimate of the VLBA resources needed to complete the program of research
  4. Clear statements about the importance of each proposal to the thesis as a whole.

The plan provides some assurance against a dissertation being impaired by an adverse review of a proposal when the full scope of the thesis is not seen. The plan can be submitted via NRAO Interactive Services. Students are reminded to submit their plan comfortably in advance of the proposal deadline. Thesis plans must be in pdf format so science reviewers can easily access the plans. Students who have not yet graduated but have active plans on file should update those plans to a pdf format if they are not already in that form.

Advertised Capabilities

Proposers that request VLBA capabilities that are not advertised in this Call for Proposals or the Observational Status Summary should first discuss such proposals with the VLBA staff by using the helpdesk (this means beginning such discussions well in advance of the proposal deadline).   In addition, such requests should be clearly stated and justified in the Technical Justification of the proposal.  Technical reviewers will determine the effect such requests may have on operational readiness of the VLBA.  If it is found that those requests are detrimental to normal operations, they will not be approved, or be approved only on a "best effort" basis.  Some capabilities that are not advertised may be good candidates for the VLBA RSRO program.

Tips for Proposers

LBO will use the panel-based NRAO proposal evaluation and time allocation infrastructure. That is, members of the scientific community are responsible for reviewing proposals based on their scientific merit through eight Science Review Panels. As a means of broadening the scientific perspective of its reviewers, and of increasing the participation of the wider astronomy and astrophysics community in the science programs of LBO, GBO and NRAO facilities, SRP membership is deliberately selected to include some colleagues that are not necessarily experts in radio observational techniques. This being the case, we encourage proposers to consider the following when preparing their proposals:

  1. Avoid the use of radio astronomy jargon
  2. Do not assume the reader is familiar with a particular observing technique - explain it briefly
  3. Do not assume the reader is familiar with an earlier rationale for a developing line of research - provide adequate historical context and connect the dots as necessary
  4. Describe previous observations and publications relevant to the proposed observations
  5. If a particular point source or brightness temperature sensitivity is required, justify it.
  6. In many imaging observations the time required to accumulate sufficient UV coverage will exceed the amount of time required to reach the required sensitivity.  Make sure to request sufficient time to meet the needs of the observation.

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.
