Dust Survival in Galactic Outflows: Insights from a New Suite of High-Resolution Simulations
Dust is a small but deeply influential component of galaxies. By regulating star formation, influencing chemical evolution, reprocessing starlight into the infrared, and more, dust affects both our view of galaxies and their overall evolution. Recently, observations have revealed that vast populations of dust also exist outside of galaxies, far from the star-forming regions where dust grains form, presenting an untapped well of information on the galactic baryon cycle and the role dust plays in it. In this talk, I will present my efforts to uncover the source and nature of extragalactic dust through the use of massive simulations of dusty galactic outflows, made using the GPU-based hydrodynamics code, Cholla. I will also discuss how these simulations can be directly compared to cutting-edge observations of dusty galactic outflows from JWST using a novel model for PAH heating and emission.
