Exoplanet characterization synergies between JWST and Roman

In only its first year of science operations, JWST has already revolutionized the field of exoplanet atmospheric characterization by showcasing the spectra of transiting exoplanets with an unprecedented degree of detail. This, in turn, has inspired observational and theoretical work in the field in order to understand how the chemical makeup of those distant worlds varies from system to system, and whether trends can be found to understand exoplanet atmospheres as a population. The Nancy Grace Roman Space Telescope's Galactic Bulge Time Domain Survey is set to become a key player in this endeavor through its expected yield of over ~100,000 transiting exoplanets. In this talk, I will outline the exoplanet characterization opportunities Roman will enable thanks to its exquisite multi-band photometric precision, ranging from multi-band transit spectrophotometry, to phase-curve and secondary-eclipse near-infrared measurements that will enable a population-level characterization of exoplanet atmospheres on previously unexplored dimensions. Synergies between those discoveries and JWST exoplanet characterization opportunities will also be discussed
