Particle acceleration up to the synchrotron burn-off limit in relativistic magnetized turbulence
M. Lemoine, V. Bresci, L. Gremillet
In high-energy astrophysics, interpreting observed spectra hinges on understanding the competition between energy gains and radiative losses. To progress along these lines, we repo…
Deciphering the physical basis of the intermediate-scale instability
Mohamad Shalaby, Timon Thomas, Christoph Pfrommer +2
We study the underlying physics of cosmic-ray (CR) driven instabilities that play a crucial role for CR transport across a wide range of scales, from interstellar to galaxy cluster…
Particle acceleration at magnetized, relativistic turbulent shock fronts
Virginia Bresci, Martin Lemoine, Laurent Gremillet
The efficiency of particle acceleration at shock waves in relativistic, magnetized astrophysical outflows is a debated topic with far-reaching implications. Here, for the first tim…
Non-resonant particle acceleration in strong turbulence: comparison to kinetic and MHD simulations
Virginia Bresci, Martin Lemoine, Laurent Gremillet +3
Collisionless, magnetized turbulence offers a promising framework for the generation of non-thermal high-energy particles in various astrophysical sites. Yet, the detailed mechanis…
Saturation of the asymmetric current filamentation instability under conditions relevant to relativistic shock precursors
Virginia Bresci, Laurent Gremillet, Martin Lemoine
The current filamentation instability, which generically arises in the counterstreaming of supersonic plasma flows, is known for its ability to convert the free energy associated w…
Effects of reacceleration and source grammage on secondary cosmic rays spectra
Virginia Bresci, Elena Amato, Pasquale Blasi +1
The ratio between secondary and primary cosmic ray particles is the main source of information about cosmic ray propagation in the Galaxy. Primary cosmic rays are thought to be acc…
