Residual energy in weakly compressible turbulence with a mean guide field
R. Skalidis, A. Tritsis, J. R. Beattie +1
The energy distribution is a fundamental property of magnetohydrodynamic (MHD) turbulence. In strongly magnetized turbulence energy imbalances arise and are quantified by the resid…
Local relaxation and scale-dependent alignment in compressible, magnetized turbulence
James R. Beattie, Amitava Bhattacharjee
Driven net- and no-net-flux MHD turbulence simulations up to reveal sign-mixed velocity-magnetic, velocity-vorticity, and magnetic-current aligned patches below the en…
Supernovae drive large-scale, incompressible turbulence through small-scale instabilities
James R. Beattie
The sources of turbulence in our Galaxy may be diverse, but core-collapse supernovae (SNe) alone provide enough energy to sustain a steady-state galactic turbulence cascade at the…
Cascading from the winds to the disk: the universality of supernovae-driven turbulence in different galactic interstellar media
Isabelle Connor, James R. Beattie, Anne Noer Kolborg +1
Star-forming galaxies are in a state of turbulence, with one of the principle components of the turbulence sourced by the constant injection of momentum from supernovae (SNe) explo…
Comparison of magnetic diffusion and reconnection in ideal and resistive relativistic magnetohydrodynamics, ideal magnetodynamics, and resistive force-free electrodynamics
Michael P. Grehan, Tanisha Ghosal, James R. Beattie +3
High-energy astrophysical systems and compact objects are frequently modeled using ideal relativistic magnetohydrodynamic (MHD) or force-free electrodynamic (FFE) simulations, with…
