IXPE Proposals and Tools: Cycle 1
General Observer Program
Instrument & Observatory Information
Additional Opportunities to Propose for IXPE Time
IXPE solicits general observer proposals from the general scientific community. Proposals are solicited via NASA's ROSES grant solicitation process. The proposal process is divided into two phases. A Phase 1 proposal is submitted to NASA HEASARC's ARK system, containing detailed target selection forms and a concise science justification. Proposals may come from both US and non-US researchers. Phase 1 proposals are evaluated by peer review panels. Data from approved IXPE GO observations are public by default, however, GO proposal PIs can request a six month exclusive-use period, subject to peer review approval.
NASA also provides grant funding to support certain selected proposals. Selected proposals will receive a notification letter with more details and an invitation to submit a Phase 2 (budget) proposal. Phase 2 proposals are submitted to NASA's NSPIRES system. In addition, there are reporting requirements for proposals with budget awards.
The IXPE team has developed a document which describes the technical capabilities, concept of operation and key information for proposers. Download the current version IXPE Observatory Guide (2.2 MB pdf file) (released June 2022).
Additionally, the following tools may be useful in preparing IXPE proposals:
3. Grant information
PI's whose Phase-1 proposals were accepted and are eligible for funding will be invited to submit a Phase-2 (cost) proposal through NSPIRES.
NASA and the federal government have specific requirements for the reporting of results obtained by the recipients of grant funds. The document Grant and Cooperative Agreement Handbook details much of this information.
Unanticipated ToO or Directors Discretionary Time (DDT) requests for events or sources that could not have been predicted or proposed for in GO programs, can be made using the IXPE ToO request form on the IXPE project website at MSFC. The decision on whether to perform an unsolicited ToO or DDT observation will be made by the IXPE Principal Investigator or an official designee. Such ToO requests are unfunded and do not have an exclusive-use period.
