Fermi Gamma-ray Space Telescope

Fermi Guest Investigator Program

The call for Cycle-11 GI proposals closed at 16:30 EST on February 23, 2018. A total of 139 proposals were received and are currently being processed at the FSSC. A scientific peer review meeting will be held in the spring and the resulting Stage-I selections will be announced in the June 2018 time frame.

Overview of Fermi Guest Investigator Program

The Fermi Guest Investigator Program provides funding for direct analysis of Fermi data, for supporting observations in other wavebands, for complementary theoretical studies, and more. The deadline for proposals is typically in February of each year.

Fermi PIs can propose to:

  • Analyze GBM or LAT event data from the beginning of science operations
  • Analyze higher level data released by the LAT: lightcurves of bright or transient sources; and a point source catalog.
  • Carry out pointed LAT observations. However, proposers should be aware that very strong science justifications will be required in view of the probable low additional scientific benefit of such observations see the Fermi Users' Group (FUG) analysis at http://fermi.gsfc.nasa.gov/ssc/proposals/pointing_analysis/. Pointed observations will follow the same open data policy as sky survey data, i.e., they will become public immediately.
  • Support correlated observations of gamma-ray sources at other wavelengths that are directly relevant to Fermi.
  • Perform theoretical studies of gamma-ray sources.
  • Obtain observing time on the NRAO, Arecibo, VERITAS, NOAO facilities or on the INTEGRAL satellite in support of Fermi-related science (refer to these URLs for details).

Fermi proposals may be submitted by investigators at both US and non-US institutions, but only PIs or Co-Is sited at US institutions may receive funding from NASA. Proposals without any investigators sited at a US institution will be evaluated (such an evaluation may assist an investigator obtain funding from a foreign funding agency), may result in a pointed LAT observation, or may be awarded observing time through our joint program agreements.

There are two proposal classes: (1) Regular proposals with research plans that can be completed in one year, and (2) Large proposals whose research plans are more expansive and may take up to three years to complete. Regular and Large proposals have distinct page limits and budget caps and annual reporting procedures. Please refer to the Fermi appendix of the ROSES NRA for details. The large majority of selected proposals are expected to be among the Regular proposal category.

As a resource to proposers list of the titles and abstracts of programs selected in previous mission cycles is available here.

The Fermi GI Process

The Fermi GI Review is typically held in the spring, and results are communicated to the Principal Investigators several weeks later. Additional interested reviewers are always welcome. If you would like to be considered as a reviewer, please send an e-mail to the HEASARC Peer Review mailbox.

If accepted, the Principal Investigator will be notified to submit Phase 2 budget proposals through NSPIRES. Details of the submission will be provided in the proposal acceptance letter.

Supporting Materials for Submitting Fermi Proposals

  • The NASA NRA Proposers Guidebook contains generalized instructions for submitting proposals to NASA.
  • The Third LAT source catalog and a preliminary version of the Fourth LAT Catalog available on the FSSC web site as is a comprehensive suite of documentation in support of Fermi data analysis.
  • Once again, prospective proposers are encouraged to contact the Fermi Science Support Center help desk with any questions regarding the preparation and submission of Fermi Guest Investigator Proposals.

Additional Details

Fermi's proposal process will have two Phases. In Phase 1 you will submit a cover page and a scientific justification; the cover page (generated by a webform) will include a maximum budget cap and the scientific justification should include a brief management section that describes the resources required (e.g., FTE). The page limit for this section is 4 pages for a Regular proposal, and 6 pages for a Large proposal. An additional page describing technical details of your proposed NRAO, Arecibo, VERITAS, NOAO or INTEGRAL observations is required if you are applying under the joint proposal opportunity. A peer review panel will review your Phase 1 proposal, and you will submit a Phase 2 budget proposal only if your Phase 1 proposal has been tentatively accepted.
