A set of distinctive properties ruling the prompt emission of GRB 230307A and other long γ-ray bursts from compact object mergers
R. Maccary, C. Guidorzi, M. Maistrello +9
Short gamma-ray bursts (SGRBs), occasionally followed by a long and spectrally soft extended emission, are associated with compact object mergers (COMs). Yet, a few recent long GRB…

Evidence of mini-jet emission in a large emission zone from a magnetically-dominated gamma-ray burst jet
S. -X. Yi, C. -W. Wang, X. -Y. Shao +42
The second brightest GRB in history, GRB230307A, provides an ideal laboratory to study the mechanism of GRB prompt emission thanks to its extraordinarily high photon statistics and…

Magnetar emergence in a peculiar gamma-ray burst from a compact star merger
H. Sun, C. -W. Wang, J. Yang +42
The central engine that powers gamma-ray bursts (GRBs), the most powerful explosions in the universe, is still not identified. Besides hyper-accreting black holes, rapidly spinning…
