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…
Mirage Sources and Large TeV Halo-Pulsar Offsets: Exploring the Parameter Space
Yiwei Bao, Ruo-Yu Liu, Gwenael Giacinti +2
We investigate the asymmetric propagation of 100 TeV electrons (whose radiation mainly concentrates on 20--30 TeV) in turbulent magnetic fields around pulsars, using GPU-accelerate…
Mirages and Large TeV Halo-Pulsar Offsets from Cosmic Ray Propagation
Yiwei Bao, Gwenael Giacinti, Ruo-Yu Liu +2
The study of extended -ray sources usually assumes symmetric diffusion of cosmic rays. However, recent observations of multiple sources near single pulsars and significant offs…
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…
A magnetised Galactic halo from inner Galaxy outflows
He-Shou Zhang, Gabriele Ponti, Ettore Carretti +12
Magnetic halos of galaxies are crucial for understanding galaxy evolution, galactic-scale outflows, and feedback from star formation activity. Identifying the magnetised halo of th…
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…
