Observations have suggested substantial departures from pressure equilibrium in the interstellar medium (ISM) in the plane of the Galaxy, even on scales under 50 pc. Nevertheless, multi-phase models of the ISM assume at least locally isobaric gas. The pressure then determines the density reached by gas cooling to stable thermal equilibrium. We use two different sets of numerical models of the ISM to examine the consequences of supernova driving for interstellar pressures. The first set of… 
Dependence of Interstellar Turbulent Pressure on Supernova Rate
Feedback from massive stars is one of the least understood aspects of galaxy formation. We perform a suite of vertically stratified local interstellar medium (ISM) models in which supernova (SN)
Turbulent Structure of a Stratified Supernova-driven Interstellar Medium
To study how supernova feedback structures the turbulent interstellar medium, we construct 3D models of vertically stratified gas stirred by discrete supernova explosions, including vertical
GAS PROPERTIES AND IMPLICATIONS FOR GALACTIC STAR FORMATION IN NUMERICAL MODELS OF THE TURBULENT, MULTIPHASE INTERSTELLAR MEDIUM
Using numerical simulations of galactic disks that resolve scales from ~1 to several hundred pc, we investigate dynamical properties of the multiphase interstellar medium (ISM) in which turbulence is
The supernova-regulated ISM – I. The multiphase structure
We simulate the multiphase interstellar medium (ISM) randomly heated and stirred by supernovae (SNe), with gravity, differential rotation and other parameters of the solar neighbourhood. Here we
The Turbulent Interstellar Medium: Insights and Questions from Numerical Models
“The purpose of numerical models is not numbers but insight.” (Hamming) In the spirit of this adage, and of Don Cox’s approach to scientific speaking, we discuss the questions that the latest
Amplification of Interstellar Magnetic Fields by Supernova-Driven Turbulence and the Role of Dynamical Chaos
Several lines of evidence suggest that magnetic fields grow rapidly in protogalactic and galactic environments. However, mean field dynamo theory has always suggested that the magnetic fields grow
Supernova-regulated ISM. V. Space and Time Correlations
We apply correlation analysis to random fields in numerical simulations of the supernova-driven interstellar medium (ISM) with the magnetic field produced by dynamo action. We solve the
H I Density Distribution Driven by Supernovae: A Simulation Study
We model the complex distribution of atomic hydrogen (H I) in the interstellar medium (ISM) assuming that it is driven entirely by supernovae (SNe). We develop and assess two different models. In the
Simulating anisotropic thermal conduction in supernova remnants - II. Implications for the interstellar medium
We present a large number of 2.5D simulations of supernova remnants expanding into interstellar media having a range of densities, temperatures and magnetic field strengths. The simulations include
Interstellar MHD Turbulence and Star Formation
This chapter reviews the nature of turbulence in the Galactic interstellar medium (ISM) and its connections to the star formation (SF) process. The ISM is turbulent, magnetized, self-gravitating, and

The dynamic state of the interstellar medium, heated and stirred by supernovae (SNe), is simulated using a three-dimensional, nonideal MHD model in a domain extended 0.5×0.5 kpc horizontally and 2
The Distribution of Thermal Pressures in the Interstellar Medium
It is generally recognized that the interstellar medium has a vast range of densities and temperatures. While these two properties are usually anticorrelated with each other, there are nevertheless

THE interstellar medium (ISM) comprises a number of components at very different densities and temperatures, from dense molecular gas at 10 K to very diffuse plasma at 106 K. It has generally been
