On the double-adiabatic equations in the relativistic regime
Francisco Ley, Aaron Tran, Ellen G. Zweibel
We revisit the double adiabatic evolution equations and extend them to the relativistic and ultrarelativistic regimes. We analytically solve the relativistic, time-dependent drift…

Compression-Driven Kinetic Instabilities in Magnetically Arrested Disks
Vedant Dhruv, Lorenzo Sironi, Jordy Davelaar +1
Event horizon-scale observations of low-luminosity black hole accretion flows favor magnetically arrested disks, characterized by dynamically important magnetic fields ($β\lesssim1…

Drift-cyclotron loss-cone instability in 3D simulations of a sloshing-ion simple mirror
Aaron Tran, Samuel J. Frank, Ari Y. Le +11
The kinetic stability of collisionless, sloshing beam-ion (45° pitch angle) plasma is studied in a 3D simple magnetic mirror, mimicking the Wisconsin High-temperature superconduct…
