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 prompt emission spectra of gamma-ray bursts (GRBs) have long been empirically described by the Band function over the keV--MeV range, whereas several \textit{Fermi}/LAT-detecte…
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…
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…
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…
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…
Constraints on the intergalactic magnetic field strength from -ray observations of GRB 221009A
Yi-Yun Huang, Cui-yuan Dai, Hai-Ming Zhang +2
Characteristics of the cascade gamma-ray signal resulting from very-high-energy gamma-ray sources, such as gamma-ray bursts, can be used to constrain the strength and structure of…
Detection of GeV emission from an ultra-long gamma-ray burst with the Fermi Large Area Telescope
Yi-Yun Huang, Hai-Ming Zhang, Kai Yan +2
GRB 220627A, detected by Fermi Gamma-ray Burst Monitor (GBM), shows two episodes of gamma-ray emission, which are separated by a {700} s long quiescent phase. Due to similar…
Interpretation of the light curve of GeV-TeV emission from the 2021 outburst of the recurrent nova RS Ophiuchi
Jian-He Zheng, Yi-Yun Huang, Ze-Lin Zhang +3
Nova outbursts take place in binary star systems comprising a white dwarf (WD) and either a low-mass Sun-like star (classical novae) or, a red giant. GeV gamma-ray emission has bee…
