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.

AO-19 Science Proposal Schedule:

20 August 2019 Release of AO-19 XMM-Newton Announcement (managed by the ESA XMM-Newton SOC)
11 October 2019, 12:00 UTClosure of AO-19 Submission Process
mid December 2019 Results of AO-19 Announced

AO-18 funding through the GOF is available only for US PI XMM science proposals and jointly awarded Cycle 5 NuSTAR-XMM science proposals, accepted at the A or B levels. All known qualifying PIs are being notified.

For the analysis of XMM data which are no longer proprietary, funding proposals may be submitted through the ADAP. Data which are still proprietary are not eligible for funding through the ADAP.

AO-18 Call For Budget Proposals

AO-18 Budget Proposal Schedule:

12 July 2019 Release of AO-18 NASA GO Budget Announcement (managed by the GSFC GOF)
13 September 2019, 4:30 PM EDTClosure of AO-18 Budget Submission Process
late Fall 2019 Results of AO-18 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-18. 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-18:

  • NEW: Proposals are now submitted via NSPIRES. All budget proposal PIs must be registered users, and information on registering is here. Please make sure to start early if you are not already familiar with NSPIRES!

  • NSPIRES will require you to enter budget numbers and answer standard questions. You must enter your original proposal title and proposal number. In addition, you must provide the original abstract of your science proposal in the "proposal summary" field.

    A complete submission also requires the following two documents to be uploaded. The first, combined into a single PDF file, contains your budget justification narrative, the original science justification from your ESA observing propsal, and the CV and Current and Pending Support of the PI. The second combined PDF contains the signed ACORN and China certifications.

  • 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 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 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 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., 2020 Summer AAS meeting, Madison, WI, Airfare $XXX, Hotel $XXX, Registration $XXX, Board $XXX, Ground Transportation $XXX, Incidentals $XXX.

  • 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 requirements 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:
