Fermi Guest Investigator Program

Cycle-8 Stage-I Proposal Selections

NASA Headquarters has completed the stage-I selection process for the Fermi Cycle-8 Guest Investigator program. A list of the proposal titles, abstracts and PIs is now posted on this web site.

Some additional details regarding the Cycle-8 selections and a historical summary of the GI program are also available on this web site for those interested.

Fermi Cycle 8 Guest Investigator Program Stage 2 Proposal Submission Information

If you have been asked to submit a budget for your Cycle 8 proposal you will be required to use the NASA Solicitation and Proposal Integrated Review and Evaluation System (NSPIRES). The submission deadline will be posted at a later date.

Both you and your institution must be registered with NSPIRES. Because of the time this may take, register now, and if you think you are registered, check now to make sure your registration is current.

Guidelines for Preparing a Successful Stage 2 Budget Proposal

  • The total budget request can be no higher than the budget "cap" specified in your Stage-1 selection letter; please note that the requested funding for CoIs on foreign-PI proposals is expected to be substantially less than funding requested for U.S. PI proposals.
  • The assessment of the appropriate level of funding for an investigation will be based upon the factors specified in Appendix D.6. These include the perceived scope of the investigation and other sources of support relevant to this request.
  • Budget proposals from U.S. PIs and U.S. Co-Is on foreign-PI proposals will be considered in the Stage 2 review, but the cap specified in the NRA applies.
  • Sub-grants from NASA to separate non-government institutions will not be issued - the PI institution is responsible for the issuing any sub-awards to Co-I institutions.
  • For investigations with more than one U.S. CoI on a foreign-PI proposal, only a single budget proposal from a designated "budget PI" may be submitted.
  • The "budget PI" on the Stage 2 (budget) proposal may differ from the "science PI" on the Stage 1 (science justification) proposal. If so, please state this clearly in the budget narrative and provide the name of the science PI on the appropriate webform.
  • You may not use grant funding to bring a visiting foreign collaborator to work with you.
  • Fermi GI funding may be used for facilities, detectors or computers dedicated to the collection and archiving of multi-wavelength data relevant to Fermi.
  • A duly registered Authorized Official of your institution must submit your budget proposal via the NSPIRES web site (http://nspires.nasaprs.com/) following the instructions in the Summary of Solicitation of ROSES 2014. This almost definitely means that you cannot start working on your budget submission on the due date!
  • All forms are submitted electronically.

Elements of a Successful Stage 2 Budget Proposal

  • The abstract of the investigation as submitted in Stage 1 (i.e., do not resubmit the entire science proposal)
  • A summary of the budget justification (12-pt minimum font with reasonable margins), not to exceed two pages for "regular," or three pages for "large" proposals and including: a) a breakdown of the work assignments for all funded investigators, including a justification of any major purchases including workstations, b) a list with justification of proposed scientific travel, c) publication costs, and d) any cost sharing applied to this project. Please be specific when requesting funds for travel, giving the proposed destination as well as the estimated costs form registration fees, airfare, lodging, meals, etc. for each trip. Please identify the science PI if different from the budget PI.
  • A listing of any current and pending support, noting grant/contract titles, and a short synopsis of currently ongoing work
  • Budget details should be prepared according to the guidelines of the PI or Co-I institution, detailing the requested any itemized expenditures
  • For large or multi-year proposals please provide a detailed budget for each year proposed. Note however that only current year amount (once approved in the budget review) constitutes a commitment by NASA. Continuation of funding for subsequent years will be contingent upon the demonstration of satisfactory progress and available funding.
  • All required government certifications
  • A 1-2 page CV for each PI or Co-I requesting support.
  • All information that is not submitted through a webform may be uploaded in a single PDF file.

  • The NSPIRES web system provides assistance; note that the NSPIRES helpdesk is staffed 8am-6pm EST. Since NSPIRES' technical support may not be aware of the Fermi-specific aspects of Stage 2, please contact the FSSC if you receive instructions that differ from those provided here or in the letter inviting you to submit a budget.
  • Technical questions should be directed to the FSSC helpdesk.
  • Policy questions should be directed to NASA HQ.
  • Many issues relevant to the GI program are discussed on the FSSC FAQ page.

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.

Documentation for Past GI Programs

Fermi Cycle 8 Update

The stage-I selections for the Cycle-8 Guest Investigator Program have now been completed. A list is available here. The selection letters and peer evaluations will be distributed in the near future.

Proposals to the Fermi Cycle-8 program should be submitted through the ARK/RPS online facility by 16:30 EST January 22, 2015. Proposers should be aware of the several new developments.

The maximum budget cap for one and two (Regular) year proposals has been reduced to $70,000 per year. It is anticipated that the average Cycle-8 grant will be $60,000. The cap for Large Projects is unchanged. We anticipate the selection of ~30-40 Regular proposals (that could be of one or two year duration) in addition to two or three Large proposals. For additional details please refer to the Fermi appendix to the 2014 ROSES NRA, and feel free to contact the Fermi Science Support Center help desk with any questions.

An additional joint program agreement has been established with the ESA INTErnational Gamma Ray Astrophysics Laboratory (INTEGRAL). Through this joint program Fermi Guest Investigators and be awarded INTEGRAL observation time for the pursuit of their Fermi-related science objectives. Details can be found in the INTEGRAL-Fermi joint program MOU.

Another recent development is the now imminent release of the long anticipated "Pass-8" reprocessed database. Pass 8 is expected to lead to improvements including a reduction in background contamination coupled with an increased effective area, an improved point-spread function, a better understanding of the systematic uncertainties and an extension of the useful energy range for photon analysis to below 100 MeV and above a few hundred GeV. Key details can be found in Atwood et al 2013.

The Fermi - Suzaku joint will be continued in cycle 8, but with new restrictions owing to the degraded condition of the power subsystems onboard the Suzaku satellite. Any observations awarded under this joint program are subject to the constraints detailed in the Suakau AO-10 documentation. In particular, proposals requiring use of the HXD detectors will not be considered. Also, the AO-10 observation period will end after October 2015, so joint program observations will have to occur by then. It is possible that some joint observations could be scheduled prior to the formal start of Fermi Cycle 8.

Joint Observation Programs

Multiwavelength observations made in conjunction with Fermi scientific investigations have the potential to enhance the scientific return of the mission and advance the field. The Fermi project has thus established a number of joint observation programs. The Fermi GI program can award optical, radio, X-ray or gamma-ray observations through Fermi's joint programs with NRAO, NOAO, Arecibo, Suzaku, VERITAS, and INTEGRAL. Note that only a single year of joint-program observations can be awarded through the Fermi GI Program regardless of the duration of awarded Fermi support. There are a number of important technical and policy details regarding these joint programs and prospective proposers are strongly encouraged to refer to the respective MOUs:

http://fermi.gsfc.nasa.gov/ssc/proposals/veritas.html, and

Again, please note that the joint-observation programs awarded through Fermi are for one year only. We encourage all perspective proposers to consider taking advantage of these joint-program opportunities.

Important - Please Read

In recent proposal cycles about 2-5% of the submissions failed to comply with the formatting requirements that are clearly stated in the Fermi NRA, and reproduced below. Please avoid having your proposal be penalized or out-and-out rejected by following the straight forward and reasonable format requirements.

Excerpted from the Fermi NRA: "Proposals should be single-spaced, typewritten, English-language text, using one or two columns, and using an easily read font size of 12-point or larger and no more than 15 characters per horizontal inch. No smaller font should be used in the subsections of the proposal, including references, however, figure captions can be in fonts as small as 10-point. In addition, the proposal shall have no more than 5.5 lines per inch of text. Pages should have at least one-inch (2.5 cm) margins on all sides. Proposals not conforming to the format above will be declared noncompliant and rejected without any further review."

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 January 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 Suzaku or INTEGRAL satellites 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 or two years, and (2) Large proposals whose research plans are more expansive and may take up to three years to complete. Regular proposals spanning two years are intended for projects that could be partially accomplished in a single year, but would benefit from a more comprehensive multiple year study, as opposed to Large proposals whose scope cannot be accomplished in a single year. 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.

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. 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 Suzaku, 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.

The continuation into year two of Regular Projects that were approved for two years duration will not require a second scientific peer evaluation. The PIs of such projects will however be solicited by the NASA Shared Services Center (NSSC) for a progress report that will be reviewed by NASA prior to the release of year-2 funds.
