Abstract

Magnetic fields and turbulence are vital components in galactic processes including cosmic ray transport ISM structure formation and star formation However turbulence is difficult to measure observationally and the role of simulations is vital for both testing theories of ISM turbulence and gauging observational diagnostics via synthetic observations In this talk I will discuss the origins of turbulence in galaxies and its connection to the star formation process both from observations and the Illustris AREPO cosmological simulation I will also highlight how turbulence can be measured in spectral line observations of molecular clouds and diffuse gas in galaxies in order to constrain and test simulations as well as obtain important properties of turbulence such as the injection scale spectral index and Mach number Refreshments are served at 3:20pm
