Abstract:
Multiphase gas flows are ubiquitous in and around galaxies, and are responsible for regulating star formation and black hole growth. During this presentation, I will review recent breakthroughs on the micro scale interaction of turbulent mixing and radiative cooling that have introduced a paradigm shift in understanding multiphase flows. I will present a new model for galactic gas flows that, for the first time, accounts for the interplay of micro-scale phenomena with the macro-scale dynamics. This model illuminates the underlying physical processes governing galaxy formation and is the basis for a novel predictive cosmological simulation sub-grid model.
