NICER Proposals and Tools
GO Cycle 1 Proposal Selection Announcement
Posted: 1 March 2019
The NICER mission is pleased to announce that the proposal selection process for GO Cycle 1 is complete, and observations will begin March 4, 2019. Documents listing selected proposals and approved targets have been released. Target of Opportunity targets requested by more than one proposal have been prioritized according to feedback received from the review panels. If you feel a target has satisfied the trigger criteria, please contact the NICER science team via the NICER Target of Opportunity/Director's Discretionary Time Request form. Be sure to include your accepted proposal number in the scientific justification.
U.S. principal investigators will be notified directly regarding invitations to submit Phase 2 budget proposals. The due date for Phase 2 budget proposals is currently TBD.
NICER Guest Observer Program
From 2018 onward NICER solicits Guest Observer proposals from the general scientific community via NASA's ROSES Research Opportunities. A Phase 1 (Science) proposal is submitted to NASA HEASARC's ARK/RPS 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 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. These funds are limited to proposals with PIs at US institutions. 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.
The Guide for Proposers summarizes guidelines from the NASA Research Announcement for NICER Guest Observers. It also describes in detail the elements and submission method for Phase 1 (Science) NICER Guest Observer proposals, as well as for Phase 2 (Budget) proposals.
The HEASARC's Remote Proposal System (RPS) is an automated service providing Guest Observers from around the world an easy-to-use facility for submitting proposals in response to NASA Research Announcements.
The NICER Proposal Tools provide documentation of the mission and applications/files that can be used for count rate and spectral simulations in order to help potential proposers demonstrate the feasibility of their proposed NICER observations. Approximate target visibility windows can be determined and NICER-specific observation properties are described.
By agreement with NASA's Astrophysics Explorers Program, the NICER Project is required to fulfill certain science objectives. The NICER Science Team Investigations support these science objectives. Proposed Guest Observer projects that duplicate existing projects of the NICER Science Team must justify that duplication, and may not be favorably reviewed.
NICER Cycle 1 Accepted Targets
Requests for Target of Opportunity targets requested by more than one proposal have been prioritized according to feedback received from the review panels. If you feel a target has satisfied the trigger criteria, please contact the NICER science team via the NICER Target of Opportunity/Director's Discretionary Time Request form. Be sure to include your accepted proposal number in the scientific justification.
Additional opportunities to propose for NICER time
Joint programs through other observatoriesCurrently NICER has arrangements with the following observatory which makes available joint observing time:
Unsolicited NICER Target of Opportunity (ToO) or Director's Discretionary Time (DDT) Observations
The Cycle 1 GO program allows for ToO proposals to observe known sources (i.e., with known coordinates) but not to observe new sources. However, unsolicited ToO requests for transient and unpredictable phenomena, from both known and previously unknown sources, will continue to be possible through the NICER ToO request procedure.
