Collisionless Magnetorotational Turbulence in Pair Plasmas: Steady-state Dynamics, Particle Acceleration, and Radiative Cooling

We present 3D fully kinetic shearing-box (SB) simulations of pair-plasma magnetorotational turbulence with unprecedented macro-to-microscopic scale separation. We retrieve the expected fluid-model behavior of turbulent magnetic fields and angular-momentum transport, and observe fundamental differences in turbulent fluctuation spectra linked with plasma heating.
