Abstract Rayleigh–Taylor (RT) and Richtmyer–Meshkov (RM) instabilities are well-known
pathways towards turbulent mixing layers, in many cases characterized by significant mass …

Stars form within molecular clouds but our understanding of this fundamental process
remains hampered by the complexity of the physics that drives their evolution. We review our …

Magnetic reconnection, topological changes in magnetic fields, is a fundamental process in
magnetized plasmas. It is associated with energy release in regions of magnetic field …

We review the present theoretical and numerical understanding of magnetic field
amplification in cosmic large-scale structure, on length scales of galaxy clusters and beyond …

High-speed disperse multiphase flows are present in numerous environmental and
engineering applications with complex interactions between turbulence, shock waves, and …

In this chapter we review recent advances in understanding the roles that magnetic fields
play throughout the star formation process, gained through observations and simulations of …

Using three-dimensional magnetohydrodynamic simulations, we investigate general
properties of a blast wave shock interacting with interstellar clouds. The pre-shock cloudy …

Diffusive shock acceleration is a prominent mechanism for producing energetic particles in
space and in astrophysical systems. Such energetic particles have long been predicted to …

Recent radio observations have identified a class of structures, so-called radio relics, in
clusters of galaxies. The radio emission from these sources is interpreted as synchrotron …

Context. Filaments are ubiquitous in the interstellar medium, as recently emphasized by
Herschel, yet their physical origin remains elusiveAims. It is therefore important to …
