Title: Exploiting Velocity Space to Understand Plasma Heating and Non-thermal Particle Acceleration in Space Plasma Turbulence and Collisionless Shocks
What’s it about? The recent development of innovative velocity-space diagnostics that resolve the energization of particles as a function of their position in three-dimensional velocity space has opened up a new avenue for the identification of proposed kinetic particle energization mechanisms and the quantification of the resulting energization rate using single-point spacecraft measurements. The kinetic theory underlying three of these techniques: the field-particle correlation technique, subpopulation analysis of collisionless shocks, and kinetic pressure strain, will be briefly reviewed and examples will be presented of how the application of these techniques illuminates the mechanisms governing plasma heating and particle acceleration in space plasmas and provides a framework for the development of a predictive capability for the partitioning of dissipated energy among the plasma species.
