The Roman Galactic Bulge Time Domain Survey

Roman's wide-field infrared camera, with a field of view 100 times larger than the Hubble Space Telescope, will provide unique time-domain astronomy in crowded fields that have been inaccessible with previous NASA Missions. In this talk I will provide an overview of the Roman Galactic Bulge Time Domain Survey, which will obtain ~440 days of high-cadence photometry in a ~2 square degree area in the galactic bulge and the galactic center. In addition to revolutionizing our understanding of exoplanet demographics through gravitational microlensing, the data will enable a wide range of time-domain science, including asteroseismology of hundreds of thousands of red giants, the study of stellar rotation, flares and stellar multiplicity, the search for transiting planets, the detection of stellar-mass black holes and the study of unique stellar populations in the center of our galaxy.
