Energy transfer and conversion in Strongly Anisotropic Magnetohydrodynamic Turbulence
Damiano Capocci, Sean Oughton, Moritz Linkmann
In homogeneous magnetohydrodynamic (MHD) turbulence without a background magnetic field driven by mechanical forces, an exact decomposition of the energy fluxes (D. Capocci et al.,…
Direct power spectral density estimation from structure functions without Fourier transforms
Mark A. Bishop, Sean Oughton, Tulasi N. Parashar +1
Second-order structure functions and power spectral densities are popular tools in the study of statistical properties across scales, particularly for the analysis of turbulent flo…
Factors Controlling the Statistics of Magnetic Reconnection in MHD Turbulence
M. B. Khan, M. A. Shay, S. Oughton +9
We study the statistics of dynamical quantities associated with magnetic reconnection events embedded in a sea of strong background magnetohydrodynamic (MHD) turbulence using direc…
Angular dependence of third-order law in anisotropic MHD turbulence
Bin Jiang, Zhuoran Gao, Yan Yang +6
In solar wind turbulence, the energy transfer/dissipation rate is typically estimated using MHD third-order structure functions calculated using spacecraft observations. However, t…
Estimation of Effective Viscosity to Quantify Collisional Behavior in Collisionless Plasma
Subash Adhikari, Carlos Gonzalez, Yan Yang +4
While dissipation in collisional plasma is defined in terms of viscosity and resistivity, the exact functional form of dissipation i.e., the so-called dissipation function in nearl…
Magnetohydrodynamic turbulence and the associated spatial diffusion tensor of cosmic rays in dynamical galactic halos
J. Kleimann, H. Fichtner, M. Stein +3
A detailed understanding of cosmic-ray transport in galactic halos is essential for explaining various observations, such as the radio continuum measurements of synchrotron radiati…
