HEASARC support for unencypted FTP access will be ending on September 20, 2019. Please see this notice for details.

XMM-Newton Guest Observer Facility



Note that final reports for XMM-Newton GO grants are required upon completion of the grant award period. Additional instructions for submitting final grant recipient reports, as well as a required form, can be found here. Yearly progress reports are also required.

The AO-17 budget cycle has closed and PIs notified. Details about the AO-18 budget proposal cycle will be forthcoming.

AO-18 Science Proposal Schedule:

21 August 2018 Release of AO-18 XMM-Newton Announcement (managed by the ESA XMM-Newton SOC)
5 October 2018, 12:00 UTClosure of AO-18 Submission Process
late November 2018 Results of AO-18 Announced

AO-17 funding through the GOF is available only for US PI XMM science proposals accepted at the A or B levels. All known qualifying PIs have been notified. For the analysis of XMM data which are no longer proprietary, funding proposals may be submitted through the ADAP. Proprietary data are not eligible for funding through the ADAP.

AO-17 Call For Budget Proposals

AO-17 Budget Proposal Schedule:

11 June 2018 Release of AO-17 NASA GO Budget Announcement (managed by the GSFC GOF)
3 August 2018, 4:30 PM EDTClosure of AO-17 Budget Submission Process
September 2018 Results of AO-17 Budget Process Announced

NASA has released a call for budget proposals (the generic version can be found here) in support of accepted XMM-Newton AO-17 Category A and B US PI science proposals. The budget process is open only to guest observers whose primary affiliation is with a US institution.

The current schedule for the review of the budget proposals is listed above. Note, however, that the dates of events are subject to change.

Important Notes and Guidelines for AO-17:

  • PIs with split positions between US and foreign institutions must specify in the budget narrative the distribution of time that they spend at the two institutions. Also, the appointment with the US institution should be expected to continue through the funding cycle.
  • In addition, NASA funds may not be used to travel between the two institutions. For example, NASA funds may not be used for travel to a European conference or collaboration where the PI uses other funds to travel to his/her European institution.
  • There are two new assurance forms that are required for processing of government grants. One says that no funds will be made available to ACORN as well as that the recipient has no outstanding federal tax liabilities. The other states that no funds will be used to further any collaborations with Chinese organizations. These new forms can be found here here.
  • Charging of home/home office internet connection to the grant is not allowed.
  • Charging of professional association dues (e.g., AAS dues) to the grant is not allowed.
  • Charging of travel expenses of foreign Co-Is to the grant is not allowed (e.g., you can't bring your European colleague to the US for the collaboration).
  • CV's are no longer optional, they are required. The CV must also include a list of at least your most recent and important publications.
  • For any requested travel, specific costs must be listed in the budget justification, even if the event is subject to change. (E.g., 2019 Winter AAS meeting, Seattle, WA, Airfare $XXX, Hotel $XXX, Registration $XXX, Board $XXX, Ground Transportation $XXX, Incidentals $XXX.
  • Your institution's Cage Code is required on the budget form.
  • Proposals will no longer be submitted electronically. Instead, a CD containing three PDF files must be submitted with the paper hardcopy. The required files are:
    1. the ARK RPS-generated PDF file containing the Cover Page, General Form, and Budget Form
    2. the budget justification, support form, and CV, combined into one PDF file
    3. the four or five page scientific justification from the ESA observation proposal

  • Suggestions for concatenating PDF files are reproduced here from the RPS website.

    Q: How do I concatenate two or more PDFs into a single PDF in order to satisfy the file upload requirement for proposal submission?

    If you have multiple documents that need to be combined in order to create a single PDF, here are some suggestions: First, if the documents are not already in PDF format, it's best to combine them in some word processor first before generating your PDF. If that's not possible, then you will need to use some software to concatenate PDFs. There are many free software packages available for doing this. We recommend doing a web search for the latest information, but here are some possibilities:
