Galaxy formation is one of the major challenges in astrophysics. Supernovae (SNe) feedback plays a critical role in galaxy formation, but how it works remains unclear. SNe drive turbulence in the interstellar medium, regulate star formation, and launch galactic outflows. In this talk, I will first introduce our high-resolution, small-box (kilo-parsec) numerical simulations on how SNe drive outflows from a multiphase interstellar medium, and discuss the amount of mass/energy/metals that are being carried in the outflows. Next, I will talk about how we use small-box results as a sub-grid model in galaxy-scale simulations, and study how the SNe-driven outflows evolve on large scales. I will discuss how the outflows regulate the circum-galactic medium, and the observational implications on X-ray emissions.
Miao Li is a Flatiron Postdoctoral Research Fellow at Center for Computational Astrophysics (CCA), Flatiron Institute in New York City. She works on supernova feedback in galaxy formation, multiphase astrophysical flows, cosmic rays. Her works utilize heavily high-performance numerical simulations. Miao got her PhD from Astrophysics Department of Columbia University in 2017, working with Prof. Jeremiah Ostriker and Prof. Greg Bryan.
