Synchrotron-Regulated Relativistic Magnetohydrodynamic Turbulence: Emission, Polarization, and Faraday Rotation
Xiaochen Sun, Luca Comisso, Luca Comisso Lorenzo Sironi +3
Relativistic magnetized plasmas in many high-energy astrophysical systems are both turbulent and strongly radiative, yet their nonlinear dynamics and radiative outcomes remain poor…
On The Nonthermal Power Laws In Magnetized Turbulent Plasmas
Rostom Mbarek, Daniel Grošelj, Alexander Philippov
Building on recent progress in the understanding of particle transport in magnetized plasmas, we derive a scaling law for the formation of nonthermal spectral tails in mildly and s…
Distortion of a relativistic jet echoing a magnetic flux eruption
Krzysztof Nalewajko, Mateusz Kapusta, Bart Ripperda +1
Magnetized accretion onto spinning black holes can accumulate a large magnetic flux across the event horizon and launch a pair of relativistic jets via the Blandford-Znajek mechani…
Electromagnetic Precursors to Binary Neutron Star Mergers: Kinetic Simulations of Magnetospheric Flaring
Jasmine Parsons, Anatoly Spitkovsky, Alexander Philippov +1
We present the first 3D global kinetic simulations of the interacting magnetospheres of pre-merger binary neutron stars. The stars, whose magnetic moments are anti-aligned, twist t…
Synchrotron-cooled plasma distribution in the outer magnetosphere of a neutron star
Mikhail V. Medvedev, Anatoly Spitkovsky, Alexander Philippov
The guiding center formalism is employed to analyze the motion of a charged relativistic particle in an inhomogeneous magnetic field, subject to magnetic mirroring and energy loss…
High-energy Emission from Turbulent Electron-ion Coronae of Accreting Black Holes
Daniel Groselj, Alexander Philippov, Andrei M. Beloborodov +1
We develop a model of particle energization and emission from strongly turbulent black-hole coronae. Our local model is based on a set of 2D radiative particle-in-cell simulations…
