Ultra-long simulations of collisionless relativistic shocks in front-comoving frame: evidence for a steady state and its properties
Mikhail Garasev, Evgeny Derishev
We present a series of unprecedently long 2D3V PIC simulations of unmagnetized relativistic -pair shocks performed in a front-comoving frame. By implementing a moving-w…

Properties of magnetic turbulence in GRB afterglows
Evgeny Derishev
We present a model-independent way to characterise properties of the magnetic-field turbulence in the emitting regions of Gamma-Ray Burst afterglows. Our only assumption is that af…

The contemporaneous phase of GRB Afterglows -- Application to GRB~221009A
Evgeny Derishev, Tsvi Piran
The TeV observations of GRB~221009A provided us with a unique opportunity to analyze the contemporaneous phase in which both prompt and afterglow emissions are seen simultaneously.…
