EP241113a: dissipative photospheric emission from a dirty fireball
Cui-Yuan Dai, Xiang-Yu Wang, Bing Zhang
EP241113a, a soft X-ray transient detected by the Einstein Probe (EP), has an isotropic-equivalent energy () comparable to classical gamma-r…
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…
Turbulent AGN coronae as the origin of diffuse neutrinos up to PeV energies
Qi-Rui Yang, Ruo-Yu Liu, Xiang-Yu Wang
It has been shown that the turbulence acceleration in AGN coronae can account for 1-10 TeV neutrinos from some AGNs, such as the Seyfert galaxy NGC 1068. Based on this, there are a…
A fast X-ray transient with chromatic flares: signatures of violent collisions induced by late-time central engine reactivation
Shao-Yu Fu, Cui-Yuan Dai, Ai-Ling Wang +57
Extragalactic Fast X-ray Transients (EFXTs) represent an emerging class of high-energy phenomena characterized by X-ray outbursts lasting from tens to hundreds of seconds. However,…
Constraining the PeV gamma-ray emission zone of Cygnus X-3 with contemporaneous GeV timing and spectral observations
Xing-Fu Zhang, Ruo-Yu Liu, Dmitriy Khangulyan +2
Cygnus X-3 has recently been established as a variable ultra-high-energy(UHE) gamma-ray source with photons detected up to 3.7~PeV. The temporal correlation between its PeV activit…
Diagnosing the AGN population origin of TeV neutrinos with their spatial correlation
Xiao-Bin Chen, Ruo-Yu Liu, Xiang-Yu Wang
The recent detection of TeV neutrinos from nearby Seyfert galaxies (e.g., NGC 1068) by IceCube suggests that active galactic nuclei (AGNs) could make a significant contribution to…
