Could the TeV emission of starburst galaxies originate from pulsar wind nebulae?
Xiao-Bin Chen, Ruo-Yu Liu, Xiang-Yu Wang +1
While the GeV -ray emission of starburst galaxies (SBG) is commonly thought to arise from hadronic interactions between accelerated cosmic rays and interstellar gas, the origin…
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…
Ultra-High-Energy Gamma-Ray Astronomy
Zhen Cao, Songzhan Chen, Ruoyu Liu +1
Ultra-High Energy (UHE, 0.1\,PeV) -ray Astronomy is rapidly evolving into an expanding branch of the -ray astronomy with the surprising discovery of 12 PeVatrons and the d…
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…
Constraining baryon loading efficiency of AGNs with diffuse neutrino flux from galaxy clusters
Xin-Yue Shi, Ruo-Yu Liu, Chong Ge +1
The active galactic nuclei (AGNs) are widely believed to be one of the promising acceleration sites of ultrahigh-energy cosmic rays (CRs). Essentially, AGNs are powered by the grav…
Studying X-ray spectra from large-scale jets of FR II radio galaxies: application of shear particle acceleration
Jia-Chun He, Xiao-Na Sun, Jie-Shuang Wang +3
Shear particle acceleration is a promising candidate for the origin of extended high-energy emission in extra-galactic jets. In this paper, we explore the applicability of a shear…

GRAND Collaboration, Rafael Alves Batista, Aurélien Benoit-Lévy +96
The Giant Radio Array for Neutrino Detection (GRAND) is an envisioned observatory of ultra-high-energy particles of cosmic origin, with energies in excess of 100 PeV. GRAND uses la…
Constraining the jet composition of GRB 221009A with the prompt TeV emission limit
Cui-Yuan Dai, Xiang-Yu Wang, Ruo-Yu Liu +1
Recent LHAASO observations of the prompt emission phase of the brightest-of-all-time GRB 221009A imposes a stringent limit on the flux ratio between the TeV and MeV emissions, $F_{…
GRB 221009A: revealing a hidden afterglow during the prompt emission phase with Fermi-GBM observations
Hai-Ming Zhang, Yi-Yun Huang, Ruo-Yu Liu +1
Recently, LHAASO reported the detection of brightest-of-all-time GRB 221009A, revealing the early onset of a TeV afterglow. However, there is no evidence of afterglow emission at s…
