Dr Adrianne Slyz from the University of Oxford gives a talk on the role of turbulence in star formation – see the abstract below for more details.

Admission is free to CUPS members, or £2 otherwise. As always, wine and cheese will be served after the talk.

(Abstract:) Despite differences in their cosmological life stories, galaxies follow a seemingly simple script for star formation: gas transforms itself to stars at a rate which depends on the average gas surface density of a galaxy. For years, galaxy formation simulations have exploited this simple global relationship to make stars, but nature is indicating that more than gas surface density is at play. Turbulence in the star forming gas appears to be key. I will describe the evidence for this and current theoretical ideas of how turbulence shapes star formation. I will then discuss attempts to capture the effect of turbulence on star formation in high resolution cosmological simulations of individual galaxies.
