The first five years of the Nancy Grace Roman Space Telescope’s observing program will be a mix of large, community defined surveys (the Core Community Surveys) with the Wide Field Instrument (WFI); competitively selected, principal investigator-led General Astrophysics Surveys with the WFI, nominally comprising at least 25% of the Roman Space Telescope’s observing time; and a technology demonstration program with the Coronagraphic Instrument. Roman’s Core Community Surveys (CCSs), which combined are anticipated to use the majority of Roman’s observing time during the first five years, will enable a broad range of astrophysical investigations while meeting the Roman Space Telescope’s scientific mission requirements in cosmology and exoplanet demographics.
Roman’s CCSs will be defined by the astronomical community and will include a High Latitude Wide Area survey, a High Latitude Time Domain survey, and a Galactic Bulge Time Domain survey. Given the range of science topics that each survey will be capable of addressing, the Roman mission will define the CCSs via an open, inclusive, and collaborative process implemented by the Roman Science Centers at STScI and IPAC. More information on Roman CCS definition process here.
Multiple science pitches and white papers submitted by the community highlighted possible synergies between the Rubin Observatory LSST and Roman CCSs. This breakout session will provide an venue to discuss opportunities to coordinate Rubin-Roman survey strategies as part of the process of gathering community input during the Roman CCS definition process.
Keith Bechtol and Masao Sako are willing to co-chair the session.
