SN-driven turbulence and GMC properties

SN explosions are a dominant source of energy to drive the observed ISM turbulence. If giant molecular clouds (GMCs) form as density enhancements in the turbulent ISM, their properties (mean density, virial parameter, mass to magnetic flux ratio, lifetime) are inherited from those of the turbulence. However, we still know very little about the general statistical properties of SN-driven turbulence, particularly from simulations with large enough resolution to also accurately describe the physics of GMCs. I will present the results of high-resolution simulations of SN-driven turbulence in the Galactic disk, including a statistical study of both the large-scale turbulence and the resulting GMC properties.
