From Weibel seeds to collisionless dynamos beyond pair-plasmas
Lise Hanebring, James Juno, Ammar Hakim +2
Bridging the spatiotemporal scales of magnetic seed field generation and subsequent dynamo amplification in the weakly collisional intracluster medium presents an extreme numerical…

Capturing Secondary Kinetic Instabilities in Three-Dimensional Dayside Reconnection Using an Improved Gradient-Based Closure
Kolter Bradshaw, Ammar Hakim, James Juno +3
Magnetic reconnection is a highly dynamic process that excites a wide variety of kinetic waves and instabilities. Transverse current sheet instabilities such as the lower-hybrid dr…

A Parallel-Kinetic-Perpendicular-Moment Model for Magnetized Plasmas
James Juno, Ammar Hakim, Jason M. TenBarge
We describe a new model for the study of weakly-collisional, magnetized plasmas derived from exploiting the separation of the dynamics parallel and perpendicular to the magnetic fi…
