The Impact of Cosmic Ray Injection on Magnetic Flux Tubes in a Galactic Disk
Roark Habegger, Ellen G. Zweibel, Sherry Wong
In galactic disks, the Parker instability results when non-thermal pressure support exceeds a certain threshold. The non-thermal pressures considered in the Parker instability are…
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…
Near-cancellation of up- and down-gradient momentum transport in forced magnetized shear-flow turbulence
B. Tripathi, A. E. Fraser, P. W. Terry +2
Visco-resistive magnetohydrodynamic turbulence, driven by a two-dimensional unstable shear layer that is maintained by an imposed body force, is examined by decomposing it into dis…
Mechanism for Sequestering Magnetic Energy at Large Scales in Shear-Flow Turbulence
B. Tripathi, A. E. Fraser, P. W. Terry +2
Straining of magnetic fields by large-scale shear flow, generally assumed to lead to intensification and generation of small scales, is re-examined in light of the persistent obser…
Galaxies at a Cosmic-Ray Eddington Limit
Evan Heintz, Ellen Zweibel
Cosmic rays have been shown to be extremely important in the dynamics of diffuse gas in galaxies, helping to maintain hydrostatic equilibrium, and serving as a regulating force in…
