Technology and science advancing observations with Roman coronagraph informed by ground-based high-contrast imaging
7 July 2026 • 17:30 - 19:00 CEST | Room B4-M3
Abstract
The Roman Coronagraph technology demonstration focuses on achieving <1e-7 contrasts within the instrument's dark hole and our ability to detect and characterize properties of faint companions around bright stars. In this talk, I describe results from a study of potential Roman Coronagraph technology demonstration phase observations focused on these goals, informed by the ongoing OASIS survey at the Subaru Telescope. OASIS provides at least three compelling targets for the technology demonstration phase: HIP 71618 B for the core contrast goal, HIP 54515 b for characterizing the system's performance, and HIP 99770 b for atmospheric characterization.

Mona El Morsy is a postdoctoral researcher at The University of Texas at San Antonio, where she leads the development of the ExplorinG Research on Exoplanets and Technology (EGRET) optical bench, focusing on advancing astrophotonic technologies for high-contrast imaging and spectroscopy of exoplanets. Her research interests include leading observational surveys to discover and characterize exoplanets by combining high-contrast imaging with precision astrometry and radial velocity data. She earned her Ph.D. in 2023 from the Laboratoire d’Astrophysique de Marseille (France), where she conducted research on the development of a prototype instrument for the direct characterization of young giant exoplanets as part of the HiRISE project.
