A New Time-Dependent Finite Difference Method for Relativistic Shock Acceleration
Sean Delaney, Paul Dempsey, Peter Duffy +1
We present a new approach to calculate the particle distribution function about relativistic shocks including synchrotron losses using the method of lines with an explicit finite d…
Multifluid magnetohydrodynamic turbulence in weakly ionised astrophysical plasmas
Turlough P. Downes
Initial results from simulations of 4-fluid MHD turbulence in molecular clouds are presented. The species included in the simulations are ions, electrons, negatively charged dust g…
The Kelvin-Helmholtz instability in weakly ionised plasmas II: multifluid effects in molecular clouds
A. C. Jones, T. P. Downes
We present a study of the Kelvin-Helmholtz instability in a weakly ionised, multifluid MHD plasma with parameters matching those of a typical molecular cloud. The instability is ca…
The Kelvin-Helmholtz instability in weakly ionised plasmas: Ambipolar dominated and Hall dominated flows
Aoife C. Jones, Turlough P. Downes
The Kelvin-Helmholtz instability is well known to be capable of converting well-ordered flows into more disordered, even turbulent, flows. As such it could represent a path by whic…
