Additional Opportunities to Propose for NICER Time
NICER Guest Observer Program: Cycle 4
In 2018, NICER began to solicit 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. In addition, there are reporting requirements for proposals with budget awards.
Notable in Cycle 4:
NICER Cycle 4 Guide for Proposers
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.
NICER Cycle 4 Phase 1 (Science) Proposal Submission
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.
NICER Proposal Tools
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.
Additional Opportunities to Propose for NICER Observing Time
Unsolicited NICER Target of Opportunity (ToO) or Director's Discretionary Time (DDT) Observations
The Cycle 4 GO program allows for ToO proposals to observe both known and unknown sources. In addition, unsolicited ToO requests for transient and unpredictable phenomena, from both known and previously unknown sources, can be made using the the NICER ToO request form. (Please review the NICER ToO Policy before making your request.)
Joint Programs Through Other Observatories
Currently NICER has arrangements with the NuSTAR observatory which makes available joint observing time. Please see the NuSTAR Proposal page for more information about the current NuSTAR Announcement of Opportunity.
