Double-Adiabatic Equations of State for Relativistic Plasmas
Agnieszka Wierzchucka, Pablo J. Bilbao, Alexander G. R. Thomas +2
The adiabatic equation of state describes the pressure evolution of highly collisional, isotropic plasmas in terms of their density, providing a possible closure o…
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…
Fast and "lossless" propagation of relativistic electrons along magnetized non-thermal filaments in galaxy clusters and the Galactic Center region
Eugene Churazov, Lawrence Rudnick, Ildar Khabibullin +3
Relativistic leptons in galaxy clusters lose their energy via radiation (synchrotron and inverse Compton losses) and interactions with the ambient plasma. At z~0, pure radiative lo…
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…
Relativistic Magnetic Reconnection in Astrophysical Plasmas: A Powerful Mechanism of Nonthermal Emission
Lorenzo Sironi, Dmitri A. Uzdensky, Dimitrios Giannios
Magnetic reconnection -- a fundamental plasma physics process, where magnetic field lines of opposite polarity annihilate -- is invoked in astrophysical plasmas as a powerful mecha…
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-…
