Secondary Whistler and Ion-cyclotron Instabilities driven by Mirror Modes in Galaxy Clusters
Francisco Ley, Ellen G. Zweibel, Drake Miller +1
Electron cyclotron waves (whistlers), are commonly observed in plasmas near Earth and the solar wind. In the presence of nonlinear mirror modes, bursts of whistlers, usually called…

Particle-in-cell Simulations of the Magnetorotational Instability in Stratified Shearing Boxes
Astor Sandoval, Mario Riquelme, Anatoly Spitkovsky +1
The magnetorotational instability (MRI) plays a crucial role in regulating the accretion efficiency in astrophysical accretion disks. In low-luminosity disks around black holes, su…
