WFIRST Coronagraph Instrument Overview

Thu 20 Feb 2020

Virtual Lecture


The WFIRST Coronagraph Instrument (CGI) is a high-contrast imager and integral field spectrograph that will enable the study of gas giant exoplanets and circumstellar disks at visible wavelengths. Future flagship mission concepts aim to image Earth analogues with visible light flux ratios below 10^-10, and CGI is a critical intermediate step toward that goal, with predicted capability of ~10^-9. This talk will present an overview of the instrument, its key enabling technologies, and its operational plans, including its potential for gas giant exoplanet and circumstellar disk science.

Speaker: Vanessa Bailey, California Institute of Technology
