Coherent Electromagnetic Emission from Relativistic Magnetized Shocks
Lorenzo Sironi, Illya Plotnikov, Joonas Nättilä +1
Relativistic magnetized shocks are a natural source of coherent emission, offering a plausible radiative mechanism for Fast Radio Bursts (FRBs). We present first-principles 3D simu…
Influence of Ion-Neutral Damping on the Cosmic-Ray Streaming Instability: Magnetohydrodynamic Particle-in-cell Simulations
Illya Plotnikov, Eve C. Ostriker, Xue-Ning Bai
We explore the physics of the gyro-resonant cosmic ray streaming instability (CRSI) including the effects of ion-neutral (IN) damping. This is the main damping mechanism in (partia…
Multi-scale simulations of particle acceleration in astrophysical systems
A. Marcowith, G. Ferrand, M. Grech +3
This review aims at providing an up-to-date status and a general introduction to the subject of the numerical study of energetic particle acceleration and transport in turbulent as…
Physics and phenomenology of weakly magnetized, relativistic astrophysical shock waves
A. Vanthieghem, M. Lemoine, I. Plotnikov +4
Weakly magnetized, relativistic collisionless shock waves are not only the natural offsprings of relativistic jets in high-energy astrophysical sources, they are also associated wi…
The synchrotron maser emission from relativistic shocks in Fast Radio Bursts: 1D PIC simulations of cold pair plasmas
Illya Plotnikov, Lorenzo Sironi
The emission process of Fast Radio Bursts (FRBs) remains unknown. We investigate whether the synchrotron maser emission from relativistic shocks in a magnetar wind can explain the…
Magnetohydrodynamic-Particle-in-Cell Simulations of the Cosmic-Ray Streaming Instability: Linear Growth and Quasi-linear Evolution
Xue-Ning Bai, Eve C. Ostriker, Illya Plotnikov +1
The gyro-resonant cosmic-ray (CR) streaming instability is believed to play a crucial role in CR transport, leading to growth of Alfvén waves at small scales that scatter CRs, and…
