Magnetic Pressure-Density Correlation in Compressible MHD Turbulence
Thierry Passot, Enrique Vazquez-Semadeni
We discuss magnetic pressure and density fluctuations in strongly turbulent isothermal MHD flows in "1+2/3" dimensions. We first consider "simple" nonlinear MHD waves, which allow…
The Origin of Molecular Cloud Turbulence and its role on Determining the Star Formation Efficiency
Enrique Vazquez-Semadeni, Javier Ballesteros-Paredes, Ralf Klessen
We suggest that molecular cloud (MC) turbulence is a consequence of the very process of MC formation by collisions of larger-scale flows in the diffuse atomic gas, which generate t…
Numerical Models of the ISM
Enrique Vazquez-Semadeni
I review recent results from numerical simulations on the structure and dynamics of the ISM, and attempt to put together a coherent dynamical scenario. In particular, I discuss res…
Thermal Instability and Magnetic Pressure in the Turbulent ISM
Enrique Vazquez-Semadeni, Adriana Gazol, Thierry Passot +1
We review recent results on the nonlinear development of thermal instability in the context of the turbulent atomic interstellar medium (ISM). First, we pre- sent a brief summary o…
