Simulations of filaments arising from wind-swept turbulent clouds

Filamentary structures arising from wind-cloud interactions are ubiquitous in the interstellar medium. In this talk I present a comprehensive numerical study of the characteristics, formation, and dynamics of filaments arising from the interplay between supersonic winds and clouds with turbulent density, velocity, and magnetic fields. I use magnetohydrodynamic simulations with gas multi-tracking techniques to shed light on the physical mechanisms acting upon wind-swept clouds and provide measurements of the aspect ratios, internal velocity dispersions, energy densities, and magnetic pressures of the resulting filaments. Using state-of-the-art visualisation techniques, I also explain the roles of plasma instabilities, turbulence, and magnetic topologies in their evolution. At the end of the talk I discuss the relevance of this work for the study of clouds and filaments in the Galactic centre and provide my perspectives on future research in this field.
