Jets with Streaks: the Global Dynamics and Structure of Striped Poynting flux dominated Jets
Ho-Sang Chan, Anna Chashkina, Omer Bromberg +2
Striped jets, characterized by magnetically dominated regions with alternating polarity, can enable fast magnetic energy dissipation in global current sheets formed in between the…
Can magnetic reconnection power neutrino emission from AGN coronae?
Omar French, Gregory R. Werner, Mitchell C. Begelman
We investigate whether reconnection of small-scale current sheets in transrelativistic supermassive black hole (SMBH) coronae can supply the nonthermal protons needed for high-ener…
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…
Three-dimensional Dynamics of Strongly Magnetized Ion-Electron Relativistic Reconnection
Fabio Bacchini, Gregory R. Werner, Camille Granier +1
We present 3D simulations of semirelativistic collisionless magnetic reconnection, where upstream ions are subrelativistic while electrons are ultrarelativistic. We employ the real…
Particle injection in three-dimensional relativistic magnetic reconnection
Omar French, Gregory R. Werner, Dmitri A. Uzdensky
Relativistic magnetic reconnection has been proposed as an important nonthermal particle acceleration (NTPA) mechanism that generates power-law spectra and high-energy emissions. P…
Kinetic Beaming in Radiative Relativistic Magnetic Reconnection: A Mechanism for Rapid Gamma-Ray Flares in Jets
J. M. Mehlhaff, G. R. Werner, D. A. Uzdensky +1
Rapid gamma-ray flares pose an astrophysical puzzle, requiring mechanisms both to accelerate energetic particles and to produce fast observed variability. These dual requirements m…
Extreme Plasma Astrophysics
D. Uzdensky, M. Begelman, A. Beloborodov +22
This is a science white paper submitted to the Astro-2020 and Plasma-2020 Decadal Surveys. The paper describes the present status and emerging opportunities in Extreme Plasma Astro…
Non-thermal particle acceleration in collisionless relativistic electron-proton reconnection
G. R. Werner, D. A. Uzdensky, M. C. Begelman +2
Magnetic reconnection in relativistic collisionless plasmas can accelerate particles and power high-energy emission in various astrophysical systems. Whereas most previous studies…
