Magnetising the quokka code with fast, second-order accurate, error-correcting schemes for magnetohydrodynamics on GPUs
Neco Kriel, Elizabeth Cole-Kodikara, Benjamin Wibking +4
We implement a second-order accurate constrained transport (CT) magnetohydrodynamics (MHD) module with first-order flux correction in the open-source, adaptive mesh refinement (AMR…
Conservation of magnetic-helicity fluctuations due to spatial decorrelation of fluxes in decaying MHD turbulence
Justin Kin Jun Hew, David N. Hosking, Christoph Federrath +2
Hosking & Schekochihin (2021, Phys. Rev. X 11, 041005) have proposed that statistically isotropic decaying MHD turbulence without net magnetic helicity conserves the mean square fl…
The universal growth of magnetic energy during the nonlinear phase of subsonic and supersonic small-scale dynamos
Neco Kriel, James R. Beattie, Mark R. Krumholz +2
Small-scale dynamos (SSDs) amplify magnetic fields in turbulent plasmas. Theory predicts nonlinear magnetic energy growth , but this scali…
Taking control of compressible modes: bulk viscosity and the turbulent dynamo
James R. Beattie, Christoph Federrath, Neco Kriel +2
Many polyatomic astrophysical plasmas are compressible and out of chemical and thermal equilibrium, introducing a bulk viscosity into the plasma via the internal degrees of freedom…
Fundamental MHD scales -- II: the kinematic phase of the supersonic small-scale dynamo
Neco Kriel, James R. Beattie, Christoph Federrath +2
Many astrophysical small-scale dynamos (SSDs) amplify weak magnetic fields via highly compressible, supersonic turbulence, but established SSD theories have overlooked these compre…
Growth or Decay -- I: universality of the turbulent dynamo saturation
James R. Beattie, Christoph Federrath, Neco Kriel +2
The turbulent small-scale dynamo (SSD) is likely to be responsible for the magnetisation of the interstellar medium (ISM) that we observe in the Universe today. The SSD efficiently…
Fundamental scales in the kinematic phase of the turbulent dynamo
Neco Kriel, James R. Beattie, Amit Seta +1
The turbulent dynamo is a powerful mechanism that converts turbulent kinetic energy to magnetic energy. A key question regarding the magnetic field amplification by turbulence, is,…
Energy balance and Alfvén Mach numbers in compressible magnetohydrodynamic turbulence with a large-scale magnetic field
James R. Beattie, Mark R. Krumholz, Raphael Skalidis +5
Energy equipartition is a powerful theoretical tool for understanding astrophysical plasmas. It is invoked, for example, to measure magnetic fields in the interstellar medium (ISM)…
Is The Starry Night Turbulent?
James Beattie, Neco Kriel
Vincent van Gogh's painting, The Starry Night, is an iconic piece of art and cultural history. The painting portrays a night sky full of stars, with eddies (spirals) both large and…
