eXtra-Large Proposals Expressions of Interest

by Davis Murphy last modified Mar 08, 2019

NRAO/LBO/GBO issued a call for submissions of Expressions of Interest (EoI) in eXtra-Large Proposals (X-Proposals) with a deadline of 31 August 2018. The Call is online.

A total of 27 EoIs were received, demonstrating a very high level of interest in the scientific potential of such large programs on all three instruments, and covering a wide range of astronomy.

Fourteen require only VLA time. Four require VLA time plus a much smaller amount of GBT time.

One requires substantial time on both the GBT and the VLA.

Two require only VLBA time. One requires VLBA time and a much smaller amount of VLA time.

Five require only GBT time.

The total observing time summed across all 27 EoIs is as follows:

  • VLA 43,705 hours
  • VLBA 8,728 hours
  • GBT 17,537 hours

In comparison to semesters 18A-19A, the typical availability for Open Skies, PI science is:

  • VLA 3,300 hours/semester
  • VLBA 500 hours/semester
  • GBT 2,600 hours/semester

As a result of the level of interest in observing programs of this scale, NRAO anticipates issuing a Call for Proposals for eXtra-Large projects using the VLA and the VLBA in the second half of 2019. The GBT may also participate in the call. The requirements for proposals and likely availability of time are currently under consideration, as is the mechanism for review of proposals and allocation of time. As stated in the call for EoIs:

  • No time will be allocated on the basis of an EoI alone and here will be no requirement that an EoI was submitted prior to submission of a full proposal;
  • X-Proposals will probably be assessed by a somewhat different process to that used for other VLA/VLBA/GBT proposals; and
  • X-Proposal calls will probably be repeated on a longer timescale than the usual Semester cycle. 

The specific EoIs received will not be considered further by the observatories.
