On the generation of astrophysically-relevant intermittent magnetic turbulence in the laboratory
Itamar Cohen, Weipeng Yao, Archie F. A. Bott +18
Intermittent magnetic turbulence, namely the presence of non-ordered and clusterized fields, is a ubiquitous phenomenon in space and astrophysical plasmas. It is currently understo…
Intermittency in Collisionless Large-Amplitude Turbulence
Ryan Golant, Luca Comisso, Philipp Kempski +1
Large-amplitude turbulence -- characterized by a fluctuating magnetic field component, , that is stronger than the mean component, -- is generically intermittent, popula…
Self-Similar Cosmic-Ray Transport in High-Resolution Magnetohydrodynamic Turbulence
Philipp Kempski, Drummond B. Fielding, Eliot Quataert +5
We study the propagation of cosmic rays (CRs) through a simulation of magnetohydrodynamic (MHD) turbulence at unprecedented resolution of . We drive turbulence that is…
Cosmic ray and plasma coupling for isothermal supersonic turbulence in the magnetized interstellar medium
Matt L. Sampson, James R. Beattie, Romain Teyssier +5
Cosmic rays (CRs) are an integral part of the non-thermal pressure budget in the interstellar medium (ISM) and are the leading-order ionization mechanism in cold molecular clouds.…
Efficient micromirror confinement of sub-TeV cosmic rays in galaxy clusters
Patrick Reichherzer, Archie F. A. Bott, Robert J. Ewart +4
Cosmic rays (CRs) play a pivotal role in shaping the thermal and dynamical properties of astrophysical environments, such as galaxies and galaxy clusters. Recent observations sugge…
A Unified Model of Cosmic Ray Propagation and Radio Extreme Scattering Events from Intermittent Interstellar Structures
Philipp Kempski, Dongzi Li, Drummond B. Fielding +5
Intermittent magnetic structures are a plausible candidate for explaining cosmic-ray (CR) diffusion rates derived from observed CR energy spectra. Independently, studies of extreme…
