    Simulations of the small-scale turbulent dynamo by Schekochihin, A, Cowley, S, Taylor, S, Maron, J, McWilliams, J

    Published 2004
    “…The primary focus is on the case of large magnetic Prandtl numbers Prm, which is relevant for hot low-density astrophysical plasmas. A Prm parameter scan is given for the model case of viscosity-dominated (low Reynolds number) turbulence. …”

    Astrophysical gyrokinetics: turbulence in pressure-anisotropic plasmas at ion scales and beyond by Kunz, MW, Abel, IG, Klein, KG, Schekochihin, AA

    Published 2018
    “…Our theory provides a foundation for determining how pressure anisotropy affects turbulent fluctuation spectra, the differential heating of particle species and the ratio of parallel and perpendicular phase mixing in space and astrophysical plasmas.…”

    SPECTROSCOPIC DIAGNOSIS IN ELECTRONIC TEMPERATURE OF PHOTOIONISE PLASMAS by A. K. Ferouani, M. K. Inal

    Published 2015-08-01
    “…These lines appear clearly in the spectra of astrophysical plasmas. As helium-like ion, we chose two, the oxygen O<sup>6+</sup> (Z=8) and neon Ne<sup>8+ </sup>(Z=10). …”

    Estimating intermittency significance by means of surrogate data: implications for solar wind turbulence by Eliza Teodorescu, Marius Mihai Echim, Marius Mihai Echim, Marius Mihai Echim, Jay Johnson

    Published 2023-06-01
    “…Introduction: Intermittency is a property of turbulent astrophysical plasmas, such as the solar wind, that implies irregularity and fragmentation, leading to non-uniformity in the transfer rate of energy carried by nonlinear structures from large to small scales. …”

    The Origin of Persistently Nonthermal Solar Wind Electrons: the Steady Electron Runaway Model's Demonstration of Dreicer Bifurcation using Measured and Ion–Electron Coulomb Drag by Jack D. Scudder

    Published 2023-01-01
    “…This documentation quantitatively establishes Coulomb runaway physics as the missing determinant of the ubiquitous nonthermal solar wind eVDF. Astrophysical plasmas, like stellar winds, are unavoidably inhomogeneous, requiring ${{\mathbb{E}}}_{\parallel }$ to enforce quasi-neutrality. …”

    Isochoric generation and spectroscopic diagnosis of high energy-density systems by Humphries, O

    Published 2020
    “…</p> <p>This thesis describes a set of experiments to isochorically generate and characterise WDM and HED systems relevant to astrophysical plasmas and Inertial Confinement Fusion. The focus of this work is on using measured X-ray Emission Spectroscopy or Resonant Inelastic X-ray Scattering (RIXS) spectra to bound the conditions present in the laser target, and using Single Photon Counting informed techniques to maximise the signal/noise in recovered spectra. …”
