Special Session SS11  4 July 2016

The interplay between turbulence and micro-physical processes

Aims and scope

Turbulence is omnipresent in the interstellar medium, from subsonic to supersonic depending on the phase where it operates. With the advent of large spectroscopic mapping capabilities probing the kinematics of the neutral and ionized phases, it is now possible to probe the gas turbulence over a broad range of densities and temperature. Turbulence is a key player not only for the the gas structure and the rate of star formation. It also impacts the gas thermodynamics as a heat source in the dissipation regions, the propagation of cosmic rays, the properties of dust grains and the gas chemistry. Turbulence has a strong influence on the transition between atomic and molecular hydrogen, the formation of hydrides and more generally the interstellar chemistry. Numerical simulations are now able to capture the multiphase nature of the ISM but cannot include all aspects. Discussions and exchanges between observers and modelers are therefore necessary to identify the challenges and diagnostic tools. This special session during EWASS 2016 aims at presenting recent theoretical and observation results, and at discussing perspectives for the future. Oral and poster contributions are welcome.
