Roman/CGI

The Roman/CGI instrument is a cutting-edge technological demonstrator designed to block the overwhelming glare of host stars so astronomers can directly image and study faint exoplanets and circumstellar disks in visible and near-infrared light. Unlike ground-based adaptive optics systems, Roman/CGI operates from space, allowing for unprecedented starlight suppression using deformable mirrors, complex masks, and advanced wavefront control. 

Our group is part of the The Coronagraph Community Participation Program (CPCP) which is a collaborative initiative created by NASA to prepare the global astronomy community for the operations of the Roman Space Telescope's Coronagraph Instrument (CGI). We are particularly involved into the Reflected Light of Exoplanets programme and the Self-Luminous programme. Our activiites include the preparation of the target selection, the vetting reference survey, the determination of the spectral energy distribution of Self-Luminous planets in the visible or the exploration of the detection limits and detection yields of Roman/CGI compared to other instruments and space missions.
