Electron and ion energization in relativistic plasma turbulence
Vladimir Zhdankin, Dmitri A. Uzdensky, Gregory R. Werner +1
Electron and ion energization (i.e., heating and nonthermal acceleration) is a fundamental, but poorly understood, outcome of plasma turbulence. In this work, we present new result…
Analytical Properties of Linear Electrostatic Waves in Two-Component Quantum and Classical Plasmas
Shane Rightley, Dmitri Uzdensky
We examine the properties of linear electrostatic waves in unmagnetized quantum and classical plasmas consisting of one or two populations of electrons with analytically tractable…
Bright gamma-ray flares powered by magnetic reconnection in QED-strength magnetic fields
K. M. Schoeffler, T. Grismayer, D. Uzdensky +2
Strong magnetic fields in magnetospheres of neutron stars (especially magnetars) and other astrophysical objects may release their energy in violent, intense episodes of magnetic r…
GRB and blazar jets shining through their stripes
Dimitrios Giannios, Dmitri A. Uzdensky
Black-hole driven relativistic astrophysical jets, such as blazars and gamma-ray bursts (GRBs), are powerful sources of electromagnetic radiation. Their emission is powered by some…
System-size convergence of nonthermal particle acceleration in relativistic plasma turbulence
Vladimir Zhdankin, Dmitri A. Uzdensky, Gregory R. Werner +1
We apply collisionless particle-in-cell simulations of relativistic pair plasmas to explore whether driven turbulence is a viable high-energy astrophysical particle accelerator. We…
Particle acceleration in relativistic magnetic reconnection with strong inverse-Compton cooling in pair plasmas
Gregory R. Werner, Alexander A. Philippov, Dmitri A. Uzdensky
Particle-in-cell (PIC) simulations have shown that relativistic collisionless magnetic reconnection drives nonthermal particle acceleration (NTPA), potentially explaining high-ener…
