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…
On the origin of ~ 100 TeV neutrinos from the Seyfert galaxy NGC 7469
Qi-Rui Yang, Xiao-Bin Chen, Ruo-Yu Liu +2
The origin of TeV-PeV neutrinos detected by IceCube remains largely unknown. The most significant individual neutrino source is the close-by Seyfert galaxy NGC 1068 at 4.2 leve…
The Stochastic Dissipation Model for the Steady State Neutrino and Multi-Wavelength Emission of TXS 0506+056
Zhen-Jie Wang, Ruo-Yu Liu, Xiang-Yu Wang
The blazar TXS 0506+056 has been suggested to be a potential high-energy neutrino source thanks to the observations of IceCube, which found outburst-like neutrino emissions during…
Could the neutrino emission of TXS 0506+056 come from the accretion flow of the supermassive black hole?
Qi-Rui Yang, Ruo-Yu Liu, Xiang-Yu Wang
High-energy neutrinos from the blazar TXS 0506+056 are usually thought to arise from the relativistic jet pointing to us. However, the composition of jets of active galactic nuclei…
Potential Contribution of Young Pulsar Wind Nebulae to Galactic High-Energy Neutrino Emission
Xuan-Han Liang, Xiao-Bin Chen, Ben Li +2
Pulsar wind nebulae (PWNe), especially the young ones, are among the most energetic astrophysical sources in the Galaxy. It is usually believed that the spin-down energy injected f…
