NICER Guest Observer Cycle 1 (ROSES 2018)

Funding Agency:
National Aeronautics and Space Administration

The Neutron Star Interior Composition Explorer (NICER) is an X-ray experiment on the International Space Station dedicated to high-resolution timing and spectroscopy of neutron stars and other rapidly variable X-ray sources in the 0.2-12 keV band. Following the end of its prime mission, NASA is initiating a Guest Observer (GO) program during a "bridge" mission extension that bridges the period between the prime mission and the Senior Review-recommended extended mission, should the Senior Review committee meeting in Spring 2019 recommend it. Proposals for observations with NICER addressing all areas of astrophysics are solicited, with a limited amount of funding available in FY19. 

Proposers also have the opportunity to request coordinated NuSTAR observations of their proposed NICER targets. A total of up to 400 ks of NuSTAR observing time is available within this Cycle. 

Proposals will be submitted in two stages, with Phase 1 focusing on the science goals and observation parameters. Selected Phase-1 proposers will be invited to submit a budget for Phase 2. Proposers may request an exclusive-use period of up to 6 months for GO data in this Cycle; by default, data will be subject to the existing NICER datarelease policy (validated data are made available in the public HEASARC archive within two weeks of acquisition), with no exclusive-use period.

Deadline for Phase 1 proposals: Dec. 20, 2018
