A Narrow Uniform Core with a Wide Structured Wing: Modeling the TeV and Multi-wavelength Afterglows of GRB 221009A
Jian-He Zheng, Xiang-Yu Wang, Ruo-Yu Liu +1
The TeV afterglow of the BOAT GRB 221009A was interpreted as arising from a narrow jet while the radio to X-ray afterglows were interpreted as arising from a wide structured jet. H…

Insights from LHAASO and IceCube into the origin of the Galactic diffuse TeV--PeV emission
Kai Yan, Ruo-Yu Liu, Rui Zhang +3
The high-energy diffuse gamma-ray emission and neutrino emission are expected from the Galactic plane, generated by hadronuclear interactions between cosmic rays (CR) and interstel…

Evidence for a compact stellar merger origin for GRB 230307A from Fermi-LAT and multi-wavelength afterglow observations
Cui-Yuan Dai, Chen-Lei Guo, Hai-Ming Zhang +2
GRB 230307A is the second brightest gamma-ray burst (GRB) ever detected over 50 years of observations and has a long duration in the prompt emission. Two galaxies are found to be c…
