NICER GO – Cycle 5 Revised Text and Phase-1 Due Date Delay

D.11 NICER General Observer (GO) – Cycle 5 solicits proposals for observations with the Neutron Star Interior Composition Explorer (NICER), an X-ray experiment on the International Space Station (ISS) dedicated to high-resolution timing and spectroscopy of neutron stars and other rapidly variable X-ray sources in the 0.2–12 keV band. All areas of astrophysics are solicited, with at least 7.5 Ms of available time and a limited amount of funding available in Cycle 5. Moreover, NICER Cycle 5 proposers may request up to 400 ks of time with NuSTAR, up to 200 ks with Swift, or up to 300 2-minute and 50 20-sec cadence windows for TESS.

ROSES-2022 Amendment 21 delays the Phase-1 due date and releases revised text for NICER GO – Cycle 5. The due date for Phase-1 proposals has been delayed to 4:30p/Eastern/3:30p Central/2:30p Mountain/1:30p Pacific on 14 September 2022, submitted via ARK/RPS. New text has been added to Sections 1.1, 1.3.3, and 2.3, regarding joint observing programs with NuSTAR, Swift, and the Transiting Exoplanet Survey Satellite (TESS).
