An extra hard spectral component peaking at sub-GeV in the prompt emission of GRB 260226A
Yi-Yun Huang, Hai-Ming Zhang, Ruo-Yu Liu +1
The paper reports the detection of an extra hard spectral component peaking at sub‑GeV energies in the prompt emission of GRB 260226A, analyzes its time‑resolved spectra with GBM a…
Ultrahigh-Energy Gamma-ray Emission Associated with Black Hole-Jet Systems
The LHAASO Collaboration, Zhen Cao, Felix Aharonian +315
Black holes (BH), one of the most intriguing objects in the universe, can manifest themselves through electromagnetic radiation initiated by the accretion flow. Some stellar-mass B…
A Giant Peanut-shaped Ultra-High-Energy Gamma-Ray Emitter Off the Galactic Plane
Zhen Cao, Felix Aharonian, Yunxiang Bai +312
Ultra-high-energy (UHE), exceeding 100 TeV (10^12 electronvolts), γ-rays manifests extreme particle acceleration in astrophysical sources. Recent observations by γ-ray telescopes…
A two-hump spectrum in the prompt emission of GRB 240825A
Hai-Ming Zhang, Zi-Qi Wang, Cui-Yuan Dai +4
An extra hard spectral component that extends to GeV energies, in additional to the typical sub- MeV Band component, appears in several gamma-ray burst (GRBs) detected by Fermi Lar…
Constraints on Cosmic Rays Acceleration in Bright Gamma-ray Bursts with Observations of Fermi
Xing-Fu Zhang, Ruo-Yu Liu, Hai-Ming Zhang +3
Gamma-ray bursts (GRBs) are widely suggested as potential sources of ultrahigh-energy cosmic rays (UHECRs). The kinetic energy of the jets dissipates, leading to the production of…
Detection of a new GeV source in the outer region of the Coma cluster: a signature of external accretion shock ?
Xiao-Bin Chen, Kai Wang, Yi-Yun Huang +4
The supersonic flow motions associated with infall of baryonic gas toward sheets and filaments, as well as cluster mergers, produces large-scale shock waves. The shocks associated…
