GRB 241030A: a bright afterglow challenging forward shock emission
J. -G. Ducoin, C. Pellouin, V. Aivazyan +97
Gamma-Ray Burst GRB 241030A (z = 1.411) exhibited a bright afterglow (similar to GRB 221009A), detected across gamma-ray, X-ray, UV, and optical bands, providing a probe of GRB aft…

Thermal Electrons in an Ultra-Relativistic Shock Shape the Optical Afterglow of GRB 250702F
Martin JelÃnek, 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 OndÅ…

From precursor to afterglow: The complex evolution of GRB 210312B
M. JelÃnek, S. A. Grebenev, P. Yu. Minaev +15
Long gamma-ray bursts (GRBs) are characterized by a brief gamma-ray flash followed by a longer-lasting multiwavelength afterglow. The basic mechanism is largely understood, and the…
