Dissipation and particle acceleration at intermittent structures with velocity and magnetic shear: Interaction of Kelvin-Helmholtz and Drift-Kink instabilities
Tsun Hin Navin Tsung, Gregory R. Werner, Dmitri A. Uzdensky +1
We present two-dimensional (2D) particle-in-cell simulations of a magnetized, collisionless, relativistic pair plasma subjected to combined velocity and magnetic-field shear, a sce…
Does magnetic field promote or suppress fragmentation in AGN disks? Results from local shearing box simulations with simple cooling
Tsun Hin Navin Tsung, Mitchell C. Begelman, Philip J. Armitage +2
Accretion disks in Active Galactic Nuclei (AGN) are predicted to become gravitationally unstable substantially interior to the black hole's sphere of influence, at radii where the…
Dissipation and particle acceleration in astrophysical jets with velocity and magnetic shear: Interaction of Kelvin-Helmholtz and Drift-Kink Instabilities
Tsun Hin Navin Tsung, Gregory R. Werner, Dmitri A. Uzdensky +1
We present 2D particle-in-cell simulations of a magnetized, collisionless, relativistic pair plasma subjected to combined velocity and magnetic-field shear, a scenario typical for…
The Cosmic Ray Staircase: the Outcome of the Cosmic Ray Acoustic Instability
Tsun Hin Navin Tsung, S. Peng Oh, Yan-Fei Jiang
Recently, cosmic rays (CRs) have emerged as a leading candidate for driving galactic winds. Small-scale processes can dramatically affect global wind properties. We run two-moment…
Fluid Simulations of Cosmic Ray Modified Shocks
Tsun Hin Navin Tsung, S. Peng Oh, Yan-Fei Jiang
We consider cosmic ray (CR) modified shocks with both streaming and diffusion in the two-fluid description. Previously, numerical codes were unable to incorporate streaming in this…
