Signatures of Energy Dissipation and Phase-Space Dynamics in Eulerian Vlasov-Maxwell Turbulence and Reconnection

POSTER

Abstract

Turbulence and magnetic reconnection are the two primary mechanisms responsible for the conversion of stored magnetic energy into particle energy in space and astrophysical plasmas. The magnetospheric multiscale mission (MMS) has given us unprecedented access to high cadence particle and field data of turbulence and magnetic reconnection at earth's magnetopause, including there first detailed view of the particle distribution function in and around the magnetic x-line and in the turbulent magnetosheath. Motivated by these observations, we present a studies of zero guide field reconnection and 2x-3v turbulence using the fully kinetic Eulerian Vlasov-Maxwell component of the Gkeyll simulation framework. In addition to studying the configuration space dynamics, we leverage the recently developed field-particle correlations to identify and diagnose the dominant sources of dissipation and compare the results of the field-particle correlation to guiding center energy dissipation measures and measures of energy transfer through the pressure tensor. We also compare the distribution function generated in the Gkeyll simulation to MMS magnetopause data.
