PSC for CAREER: The Physics of Stellar Feedback and Star Formation Regulation in Galaxies

Project: Research project

Project Details


This career-development plan will integrate my galaxy formation research with education and outreach efforts that will use galaxy simulations to excite thousands of people through beautiful, interactive visualizations distributed online, in classrooms, and at museums across the nation and beyond. The galaxy simulations will also serve at the basis for summer research projects for at least 10 undergraduate students, which I will recruit from under-represented minorities. The grant will support two full-time graduate students and provide partial support for a postdoctoral researcher. We will use high-resolution hydrodynamical galaxy simulations of increasing complexity to develop a systematic understanding of how stellar feedback operates and how it regulates star formation in galaxies. Specifically, we will: 1) study the origin of interstellar turbulence and the generation of galactic winds; 2) investigate the effects of time-dependent, non-equilibrium molecular chemistry on the interstellar medium (ISM) and star formation; 3) explore the effects of ionizing and photo-dissociating radiation; 4) study how magnetic fields and cosmic rays affect the ISM and galactic winds; and 5) synthesize our results in a generalized theory of star formation regulation and develop new subgrid models for use in large-volume cosmological simulations.
