This page contains information useful for community members responding to the Nancy Grace Roman Space Telescope announcement in the 2024 ROSES Call for Proposals. The opportunity will contain two categories: Wide Field Science (WFS) teams and the Coronagraph Community Participation Program (CPP).

For reference, here are the lists of the current WFS teams and the CPP.

The Roman Science Support Center (SSC) at IPAC is part of the Roman Ground System. The SSC produces science data products for the Wide Field Spectroscopy Mode and for the Galactic Bulge Time Domain Survey (GBTDS) and associated exoplanet goals. The SSC also supports Coronagraph Instrument operations. Technical details and Information about the Coronagraph Instrument to support the CPP are linked below.
