About the Cycle 1 Call for Proposals
The Cycle 1 Call for Proposals invites investigators to submit proposals to conduct scientific investigations with the Nancy Grace Roman Space Telescope. All Roman data have no proprietary period, ensuring rapid community access to all observations. The Roman General Investigator program solicits proposals for funding and compute support for the analysis of Roman WFI data (including, but not limited to, Roman's community-defined surveys), theoretical or laboratory astrophysics research, and analysis of publicly accessible ancillary data with direct relevance to the Roman mission. This solicitation also encompasses proposals for new General Astrophysics Survey (GAS) observations with WFI, with funding and compute support for data analysis. In Cycle 1, up to six new GAS programs will be selected for a combined total of no more than 1200 hours of Roman observing time. Please check the Call for more details.
About the Community-Defined Surveys
Information on the High-Latitude Wide-Area Survey (HLWAS), High-Latitude Time-Domain Survey (HLTDS), Galactic Bulge Time-Domain Survey (GBTDS), and Galactic Plane Survey are available on RDox. These surveys have been defined and recommended based on input from the astronomical community, enabling a broad range of astrophysical investigations. They are an integral part of the Roman mission and are expected to provide substantial scientific returns for all the investigators. Additional details on scheduling and availability of the data products can be found in the Call.
Please direct any questions you may have regarding RTPS and the proposal call to the Roman Help Desk.
