Dataset from: Isolation and Phase-Space Energization Analysis of the Instabilities in Collisionless Shocks

We analyze the generation of kinetic instabilities and their effect on the energiza-<br> tion of ions in non-relativistic, oblique collisionless shocks using a 3D-3V simulation<br> by dHybridR, a hybrid particle-in-cell code. At sufficiently high Mach number, quasi-<br> perpendicular and oblique shocks can experience rippling of the shock surface caused by<br> kinetic instabilities arising from free energy in the ion velocity distribution due to the<br> combination of the incoming ion beam and the population of ions reflected at the shock<br> front. To understand the role of the ripple on particle energization, we devise the new<br> instability isolation method to identify the unstable modes underlying the ripple and<br> interpret the results in terms of the governing kinetic instability. We generate velocity-<br> space signatures using the field-particle correlation technique to look at energy transfer in<br> phase space from the isolated instability driving the shock ripple, providing a viewpoint<br> on the different dynamics of distinct populations of ions in phase space. We generate<br> velocity-space signatures of the energy transfer in phase space of the isolated instability<br> driving the shock ripple using the field-particle correlation technique. Together, the<br> field-particle correlation technique and our new instability isolation method provide a<br> unique viewpoint on the different dynamics of distinct populations of ions in phase space<br> and allow us to completely characterize the energetics of the collisionless shock under<br> investigation.
