A Framework for Multiphase Galactic Wind Launching using TIGRESS
Chang-Goo Kim, Eve C. Ostriker, Drummond B. Fielding +6
Galactic outflows have density, temperature, and velocity variations at least as large as that of the multiphase, turbulent interstellar medium (ISM) from which they originate. We…
The sensitivity of stellar feedback to IMF averaging versus IMF sampling in galaxy formation simulations
Matthew C. Smith
Galaxy formation simulations frequently use Initial Mass Function (IMF) averaged feedback prescriptions, where star particles are assumed to represent single stellar populations th…
Efficient early stellar feedback can suppress galactic outflows by reducing supernova clustering
Matthew C. Smith, Greg L. Bryan, Rachel S. Somerville +4
We present a novel set of stellar feedback models, implemented in the moving-mesh code Arepo, designed for galaxy formation simulations with near-parsec (or better) resolution. The…
First results from SMAUG: Insights into star formation conditions from spatially-resolved ISM properties in TNG50
Bhawna Motwani, Shy Genel, Greg L. Bryan +11
Physical and chemical properties of the interstellar medium (ISM) at sub-galactic (kpc) scales play an indispensable role in controlling the ability of gas to form stars. As…
