Star formation lies at the center of a web of processes that drive cosmic evolution:
generation of radiant energy, synthesis of elements, formation of planets, and development …

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 …

We present two new Lagrangian methods for hydrodynamics, in a systematic comparison
with moving-mesh, smoothed particle hydrodynamics (SPH), and stationary (non-moving) …

The role of turbulence and magnetic fields is studied for star formation in molecular clouds.
We derive and compare six theoretical models for the star formation rate (SFR)—the …

We present simulations of the multiphase interstellar medium (ISM) at solar neighbourhood
conditions including thermal and non-thermal ISM processes, star cluster formation, and …

Understanding the physics of turbulence is crucial for many applications, including weather,
industry and astrophysics. In the interstellar medium,, supersonic turbulence plays a crucial …

We study the interactions of a relativistic jet with a dense turbulent gaseous disc of radius∼
2 kpc. We have performed a suite of simulations with different mean density, jet power, and …

Context. Density and velocity fluctuations on virtually all scales observed with modern
telescopes show that molecular clouds (MCs) are turbulent. The forcing and structural …

We study the star formation efficiency (SFE) in simulations and observations of turbulent,
magnetized, molecular clouds. We find that the probability density functions (PDFs) of the …

We present Phantom, a fast, parallel, modular, and low-memory smoothed particle
hydrodynamics and magnetohydrodynamics code developed over the last decade for …
