A Linear Instability and Damping in the Acoustic Dispersion Relation of Fluids Subject to Inverse Compton Drag
Yiting Wang, Sebastian Heinz, Vladimir Zhdankin
Radiation drag from inverse-Compton scattering of an external radiation field changes the acoustic dispersion relation of a relativistic fluid. We derive the linear dispersion rela…
Nonthermal Particle Acceleration by Magnetic Pumping in Pulsating Plasmas
Giuseppe Arrò, Vladimir Zhdankin, Fabio Bacchini
We present a new "pulsating box" setup to investigate particle acceleration in high-beta plasmas undergoing compression-expansion cycles. Our fully kinetic simulations show that pa…
Radiative relativistic turbulence as an in situ pair-plasma source in blazar jets
John Mehlhaff, Muni Zhou, Vladimir Zhdankin
As powerful gamma-ray engines, blazars -- relativistic plasma jets launched toward Earth from active galactic nuclei -- are manifestly high-energy particle accelerators. Yet, exact…
Energy Diffusion and Advection Coefficients in Kinetic Simulations of Relativistic Plasma Turbulence
Kai W. Wong, Vladimir Zhdankin, Dmitri A. Uzdensky +2
Turbulent, relativistic nonthermal plasmas are ubiquitous in high-energy astrophysical systems, as inferred from broadband nonthermal emission spectra. The underlying turbulent non…
First-principles measurement of ion and electron energization in collisionless accretion flow
Evgeny A. Gorbunov, Fabio Bacchini, Vladimir Zhdankin +3
We present the largest 3D Particle-in-Cell shearing-box simulations of turbulence driven by the magnetorotational instability, for the first time employing the realistic proton-to-…
Scale Statistics of Current Sheets in Relativistic Collisionless Plasma Turbulence
Roberto F. Serrano, Joonas Nättilä, Vladimir Zhdankin
We analyze distributions of the spatial scales of coherent intermittent structures -- current sheets -- obtained from fully kinetic, two-dimensional simulations of relativistic pla…
