Observational Benchmarks of Chemical Evolution from Extreme Emission Line Galaxies
Danielle Berg (University of Texas in Austin)

The advent of the James Webb Space Telescope has opened our first window onto detailed abundance studies of high redshift (z > 6) extreme emission line galaxies. The coming years will provide the first spectroscopic samples of these galaxies in the epoch of reionization with which we can constrain their chemical compositions and histories and resulting conditions that shaped the escape of ionizing photons. As we build our samples of high-ionization nebular emission lines and absorption profiles of outflowing gas, we can begin to understand how the time-dependent nature of elemental production affects our interpretation of different epochs of galaxies and the resulting strung-together evolutionary story. I will present recent HST and JWST observations of the dynamic ISM across multiple epochs and the lessons we are learning about chemical evolution, star formation histories, and feedback prescriptions.
