Gamma-ray bursts (GRBs) are the most electromagnetically luminous cosmic explosions.
They are powered by collimated streams of plasma (jets) ejected by a newborn stellar-mass …

Gamma-ray burst (GRB) afterglow emission is believed to be produced by synchrotron
emission of electrons accelerated to high energy by a relativistic collisionless shock …

ABSTRACT GRB 120308A, a long duration γ-ray burst (GRB) detected by Swift, was
distinguished by a highly polarized early optical afterglow emission that strongly suggests …

Cosmic rays accelerated by a shock form a streaming distribution of outgoing particles in the
foreshock region. If the ambient fields are negligible compared to the shock and cosmic ray …

Abstract We present Atacama Large Millimeter/submillimeter Array 97.5 GHz total intensity
and linear polarization observations of the mm-band afterglow of GRB 190114C spanning …

Collisionless shocks are commonly argued to be the sites of cosmic-ray (CR) acceleration.
We study the influence of CRs on weakly magnetized relativistic collisionless shocks and …

The deaths of massive stars are sometimes accompanied by the launch of highly relativistic
and collimated jets. If the jet is pointed towards Earth, we observe a 'prompt'gamma-ray burst …

We show that the relativistic two-stream instability can naturally generate strong magnetic
fields with 10-5–10-1 of the equipartition energy density, in the collisionless shocks of …

We present extensive radio and millimeter observations of the unusually bright GRB
130427A at z= 0.340, spanning 0.67–12 days after the burst. We combine these data with …

Motivated by the detection of very-high-energy (VHE) gamma rays deep in the afterglow
emission of a gamma-ray burst (GRB), we revisit predictions of the maximum energy to …
