Turbulence and Magnetic Fields in Astrophysical Plasmas by Schekochihin, A, Cowley, S

“…They are also good examples of a complication that is more or less generic in astrophysical plasmas: the MHD description is, in fact, insufficient for astrophysical turbulence and plasma physics must make an entrance.…”

Amplitude limits and nonlinear damping of shear-Alfvén waves in high-beta low-collisionality plasmas by Squire, J, Schekochihin, A, Quataert, E

“…The effect has interesting implications for the physics of magnetized turbulence in the high-β conditions that are prevalent in many astrophysical plasmas.…”

A stringent limit on the amplitude of alfvénic perturbations in high-beta low-collisionality plasmas by Squire, J, Quataert, E, Schekochihin, A

“…Such a restrictive bound on shear-Alfvén-wave amplitudes has far-reaching implications for the physics of magnetized turbulence in the high-β conditions prevalent in many astrophysical plasmas, as well as for the solar wind at ∼1 au where β ≳ 1.…”

Nonlinear mirror instability by Rincon, F, Schekochihin, A, Cowley, S

“…Slow dynamical changes in magnetic-field strength and invariance of the particles' magnetic moments generate ubiquitous pressure anisotropies in weakly collisional, magnetized astrophysical plasmas. This renders them unstable to fast, small-scale mirror and firehose instabilities, which are capable of exerting feedback on the macroscale dynamics of the system. …”

“…<p>Thefirehose and mirror instabilities are thought to arise in a variety of space and astrophysical plasmas, constraining the pressure anisotropies and drifts between particle species. …”

A model of nonlinear evolution and saturation of the turbulent MHD dynamo by Schekochihin, A, Cowley, S, Hammett, G, Maron, J, McWilliams, J

“…This regime is very common in low-density hot astrophysical plasmas. During the early (kinematic) stage, weak magnetic fluctuations grow exponentially and concentrate at the resistive scale, which lies far below the hydrodynamic viscous scale. …”

Self-inhibiting thermal conduction in a high-β, whistler-unstable plasma by Komarov, S, Schekochihin, A, Churazov, E, Spitkovsky, A

Turbulent dynamo in a collisionless plasma by Rincon, F, Califano, F, Schekochihin, A, Valentini, F
