Can winds driven by active galactic nuclei account for the extragalactic gamma-ray and neutrino backgrounds?
Ruo-Yu Liu, Kohta Murase, Susumu Inoue +2
Various observations are revealing the widespread occurrence of fast and powerful winds in active galactic nuclei (AGNs) that are distinct from relativistic jets, likely launched f…
The energy distribution of relativistic electrons in the kilo-parsec scale jet of M87 with Chandra
Xiao-Na Sun, Rui-Zhi Yang, Frank M. Rieger +2
The X-ray emission from the jets in Active Galactic Nuclei (AGN) carries important information on the distributions of relativistic electrons and magnetic fields on large scales. W…
TeV gamma-ray observations of the binary neutron star merger GW170817 with H.E.S.S
H. E. S. S. Collaboration, :, H. Abdalla +250
We search for high-energy gamma-ray emission from the binary neutron star merger GW170817 with the H.E.S.S. Imaging Air Cherenkov Telescopes. The observations presented here have b…
Detection of gamma-ray emission from the Coma cluster with Fermi Large Area Telescope and tentative evidence for an extended spatial structure
Shao-Qiang Xi, Xiang-Yu Wang, Yun-Feng Liang +3
Many galaxy clusters have giant halos of non-thermal radio emission, indicating the presence of relativistic electrons in the clusters. Relativistic protons may also be accelerated…
Evidence of an Internal Dissipation Origin for the High-energy Prompt Emission of GRB 170214A
Qing-Wen Tang, Xiang-Yu Wang, Ruo-Yu Liu
The origin of the prompt high-energy (MeV) emission of Gamma-ray Bursts (GRBs), detected by the Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope, is st…
Characterising the VHE diffuse emission in the central 200 parsecs of our Galaxy with H.E.S.S
H. E. S. S. Collaboration, :, H. Abdalla +256
The diffuse very high-energy (VHE, > 100 GeV) gamma-ray emission observed in the central 200 pc of the Milky Way by H.E.S.S. was found to follow the dense matter distribution in th…
Particle Acceleration in Mildly Relativistic Shearing Flows: the Interplay of Systematic and Stochastic Effects, and the Origin of the Extended High-energy Emission in AGN Jets
Ruo-Yu Liu, F. M. Rieger, F. A. Aharonian
The origin of the extended X-ray emission in the large-scale jets of active galactic nuclei (AGNs) poses challenges to conventional models of acceleration and emission. Although th…
Evidence of a spectral break in the gamma-ray emission of the disk component of Large Magellanic Cloud: a hadronic origin?
Qing-Wen Tang, Fang-Kun Peng, Ruo-Yu Liu +2
It has been suggested that high-energy gamma-ray emission () of nearby star-forming galaxies may be produced predominantly by cosmic rays colliding with the interste…
Neutrino Production in Electromagnetic Cascades: An extra component of cosmogenic neutrino at ultrahigh energies
Kai Wang, Ruo-Yu Liu, Zhuo Li +1
Muon pairs can be produced in the annihilation of ultra-high energy (UHE, ) photons with low energy cosmic background radiation in the intergalacti…
