Suppression of spiral density waves in collisionless accretion flows

Stephen Majeski, Matthew W. Kunz, Jason Dexter

Spiral density waves are ubiquitous phenomena in differentially rotating flows. They are non-modal, non-axisymmetric perturbations that, due to shear in the background flow, posses…

Cosmic-ray transport in inhomogeneous media

Robert J. Ewart, Patrick Reichherzer, Shuzhe Ren +6

A theory of cosmic-ray transport in multi-phase diffusive media is developed, with the specific application to cases in which the cosmic-ray diffusion coefficient has large spatial…

Self-organization in collisionless, high- turbulence

S. Majeski, M. W. Kunz, J. Squire

The MHD equations, as a collisional fluid model that remains in local thermodynamic equilibrium (LTE), have long been used to describe turbulence in myriad space and astrophysical…

On hydromagnetic wave interactions in collisionless, high- plasmas

Stephen Majeski, Matthew W. Kunz

We describe the interaction of parallel-propagating Alfvén waves with ion-acoustic waves and other Alfvén waves, in magnetized, high- collisionless plasmas. This is accomplished…

Microphysically modified magnetosonic modes in collisionless, high- plasmas

Stephen Majeski, Matthew W. Kunz, Jonathan Squire

With the support of hybrid-kinetic simulations and analytic theory, we describe the nonlinear behaviour of long-wavelength non-propagating (NP) modes and fast magnetosonic waves in…
