Numerical Study of Cosmic Ray Confinement through Dust Resonant Drag Instabilities
Suoqing Ji, Jonathan Squire, Philip F. Hopkins
We investigate the possibility of cosmic ray (CR) confinement by charged dust grains through resonant drag instabilities (RDIs). We perform magnetohydrodynamic particle-in-cell sim…

Statistical simulation of the magnetorotational dynamo
Jonathan Squire, Amitava Bhattacharjee
Turbulence and dynamo induced by the magnetorotational instability (MRI) are analyzed using quasi-linear statistical simulation methods. It is found that homogenous turbulence is u…

Magnetorotational instability: nonmodal growth and the relationship of global modes to the shearing box
Jonathan Squire, Amitava Bhattacharjee
We study the magnetorotational instability (MRI) using nonmodal stability techniques. Despite the spectral instability of many forms of the MRI, this proves to be a natural method…
