Thermal Electrons in an Ultra-Relativistic Shock Shape the Optical Afterglow of GRB 250702F
Martin Jelínek, Annarita Ierardi, Filip Novotný +8
Observing early optical emission from gamma-ray bursts (GRBs) contemporaneous with the MeV prompt emission phase remains rare, requiring rapid-response robotic facilities. The Ondř…
The effect of inverse Compton losses on particle acceleration in three-dimensional relativistic reconnection
Ian Bowyer, Dimitrios Giannios, Lorenzo Sironi
Relativistic magnetic reconnection is a key mechanism for dissipating magnetic energy and accelerating particles in astrophysics. In the absence of radiative cooling, recent partic…
Maximum Energy of Particles Accelerated in Gamma-Ray Burst Afterglow Shocks
Zhao-Feng Wu, Sofía Guevara-Montoya, Paz Beniamini +3
Particle acceleration in relativistic collisionless shocks remains an open problem in high-energy astrophysics. Particle-in-cell (PIC) simulations predict that electron acceleratio…
Relativistic Magnetic Reconnection in Astrophysical Plasmas: A Powerful Mechanism of Nonthermal Emission
Lorenzo Sironi, Dmitri A. Uzdensky, Dimitrios Giannios
Magnetic reconnection -- a fundamental plasma physics process, where magnetic field lines of opposite polarity annihilate -- is invoked in astrophysical plasmas as a powerful mecha…
Maximal Jet Energy of Gamma-Ray Bursts through the Blandford-Znajek Mechanism
Zhao-Feng Wu, Michail Damoulakis, Paz Beniamini +1
Gamma-ray bursts (GRBs) are among the most energetic events in the universe, driven by relativistic jets launched from black holes (BHs) formed during the collapse of massive stars…
Radiative Properties of Plasmoids and Plasmoid Mergers in Magnetic Reconnection
Haocheng Zhang, Lingyi Dong, Dimitrios Giannios
Magnetic reconnection is often considered as the primary particle acceleration mechanism in a magnetized blazar zone environment. The majority of radiation in the reconnection laye…
