XRISM General Observer Cycle 2 Proposals Due

28 March 2025

Due Date May 15, 2025

NSPIRES Solicitation | D.17 XRISM General Observer Cycle 2

Amended March 7, 2025

This amendment announces the solicitation in ROSES-24 of XRISM General Observer (GO) which was previously deferred to ROSES-25. Both Type-1 Phase-1 proposals and Type-2 proposals are due May 15, 2025.

There are two types of proposals with different page limits, contents, and submission procedures: Type-1 Phase-1 proposals are due at 4:30 p.m. Eastern time via ARK/RPS whereas Type-2 proposals must be submitted by the proposing organization via NSPIRES by 11:59 pm, in both cases by the date given in Tables 2 and 3 of ROSES. XRISM General Observer (GO) proposals, both Type-1 and Type-2, will be evaluated via dual-anonymous peer review and must be prepared following the guidelines in Section 2.1 and 2.2. Due to the nature of the proposed investigations, Type-1 Observational proposals do not need to include an "Open Science and Data Management Plan."

The description of the specific proposal opportunity on this page is contained in the document 'D.17 XRISM General Observer Cycle 2 – Type 1'. The document 'D.1 Astrophysics Research Program Overview' describes research activities within the NASA science division that is managing the specific proposal opportunity on this page and may impose requirements upon proposals submitted to this program element. The document 'Summary of Solicitation' describes the common requirements for all ROSES-2024 proposal opportunities. The document 'Table 1' contains the proposal check list from the Summary of Solicitation. The documents 'Table 2' and 'Table 3' contain the list of all proposal opportunities and their due dates, sorted by (full or Step-2) proposal due date or appendix number, respectively. All of these documents are kept up to date and incorporate amendments, clarifications, and corrections in a clearly identifiable manner.

An illustration of Sun-like star HD 181327 and its surrounding debris disk. The star is at top right. It is surrounded by a far larger debris disk that forms an incomplete ellpitical path and is cut off at right. There’s a huge cavity between the star and the disk. The debris disk is shown in shades of light gray. Toward the top and left, there are finer, more discrete points in a range of sizes. The disk appears hazier and smokier at the bottom. The star is bright white at center, with a hazy blue region around it. The background of space is black. The label Artist's Concept appears at lower left.
