XRISM Proposal

We are accepting submissions for the Xrism Key Program now.

XRISM proposals for the Key Program phase must be submitted through JAXA (this site). Non-registered users will need to create an ark account, regardless of whether or not they already maintain an account through NASA or ESA.

JAXA XRISM proposal system consists of ARK (Astrophysical Research Knowledgebase) and RPS (Remote Proposal System).

ARK provides a web interface to submit and store information in a database. Registration is required to access the service, which provides user authentication and group-based authorization. Users have permission to submit and/or modify the ARK database based on granular group- and user-specific settings.

ARK forms the basis for the RPS. The combination allows investigators to view and modify their proposal information after they submit their proposals (prior to the submission deadline) via RPS and upload any associated files that are needed to fulfill electronic proposal submission.
