Itô tracers: continuous-trajectory Lagrangian particles for Eulerian hydrodynamics
Eric R. Moseley, R. Teyssier, Tom Abel
Lagrangian tracer particles have long been used to track the history of individual gas parcels in hydrodynamical codes. Particles advected by the cell-centered velocity carry no re…

Nonlinear Saturation of the Acoustic Resonant Drag Instability
Ben Y. Israeli, Jonathan Squire, Eric Moseley +1
Resonant drag instabilities (RDIs) are a novel type of dust/fluid instability relevant to a diverse range of astrophysical environments. They are driven by a resonant interaction b…

Cosmic ray and plasma coupling for isothermal supersonic turbulence in the magnetized interstellar medium
Matt L. Sampson, James R. Beattie, Romain Teyssier +5
Cosmic rays (CRs) are an integral part of the non-thermal pressure budget in the interstellar medium (ISM) and are the leading-order ionization mechanism in cold molecular clouds.…
