The Role of Whistler and Ion Cyclotron Waves in Particle Escape from Mirror Modes in the Intracluster Medium
Petr Ugarov, Francisco Ley, Ellen Zweibel
Electron and ion-cyclotron waves are well known to exist in solar system plasmas but their existence and importance in galaxy clusters is an open question. Guided by numerical simu…
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…
Electron Re-acceleration via Ion Cyclotron Waves in the Intracluster Medium
Aaron Tran, Lorenzo Sironi, Francisco Ley +2
In galaxy clusters, the intracluster medium (ICM) is expected to host a diffuse, long-lived, and invisible population of "fossil" cosmic-ray electrons (CRe) with 1-100 MeV energies…
A Heating Mechanism via Magnetic Pumping in the Intracluster Medium
Francisco Ley, Ellen G. Zweibel, Mario Riquelme +3
Turbulence driven by AGN activity, cluster mergers and galaxy motion constitutes an attractive energy source for heating the intracluster medium (ICM). How this energy dissipates i…
Stochastic Ion Acceleration by the Ion-cyclotron Instability in a Growing Magnetic Field
Francisco Ley, Mario Riquelme, Lorenzo Sironi +2
Using 1D and 2D particle-in-cell (PIC) simulations of a plasma with a growing magnetic field , we show that ions can be stochastically accelerated by the ion-cyclotron (IC…
