Can Cosmic Metals Constrain the Nature of Stellar Feedback?
Paul Torrey
Massachusetts Institute of Technology



Dr. Torrey will present results from the recent Illustris and IllustrisTNG cosmological galaxy formation simulations with a focus on the evolution of cosmic metals. Illustris and IllustrisTNG are detailed galaxy formation simulations that reproduce important observations such as the galaxy stellar mass function, cosmic star formation rate density, and galaxy morphological diversity. Dr. Torrey will briefly overview the numerical framework, discuss the key physical model ingredients, and explore in detail the cosmic coevolution of galaxies and their metals. After reviewing some of the basic simulation results, Dr. Torrey will show that Illustris broadly reproduces the observed fundamental metallicity relation and argue that this relation alone may allow us to discriminate between bursty and non-bursty feedback models in the high redshift Universe with JWST.
