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…
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…
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…
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…
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…
