RAMSES-GPU: Cell-by-Cell Adaptive Mesh Refinement with Magneto-Hydrodynamics and Self-Gravity on Graphics Processing Units
Romain Teyssier, Eric Moseley, Robert V. Caddy +9
We present the implementation and optimization of the cosmological simulation code RAMSES on Graphics Processing Units (GPUs) using CUDA Fortran. This accelerated version ports the…
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.…
Dust dynamics in RAMSES -- II. Equilibrium drift velocity distributions of charged dust grains
Eric R. Moseley, Romain Teyssier
We investigate the gas-grain relative drift velocity distributions of charged astrophysical dust grains in MHD turbulence. We do this using a range of MHD-PIC simulations spanning…
Dust dynamics in RAMSES -- I. Methods and turbulent acceleration
Eric R. Moseley, Romain Teyssier, B. T. Draine
Supernova ejecta and stellar winds are believed to produce interstellar dust grains with relatively large sizes. Smaller grains can be produced via the shattering of large grains t…
Turbulent dissipation, CH abundance, H line luminosities, and polarization in the cold neutral medium
Eric R. Moseley, B. T. Draine, Kengo Tomida +1
In the cold neutral medium, high out-of-equilibrium temperatures are created by intermittent dissipation processes, including shocks, viscous heating, and ambipolar diffusion. The…
Nonlinear Evolution of Instabilities Between Dust and Sound Waves
Eric R. Moseley, Jonathan Squire, Philip F. Hopkins
We study the non-linear evolution of the acoustic 'Resonant Drag Instability' (RDI) using numerical simulations. The acoustic RDI is excited in a dust-gas mixture when dust grains…
