Dissecting the gamma-ray emissions of the nearby galaxies NGC 1068 and NGC 253
Shunhao Ji, Zhongxiang Wang, Yi Xing +2
Intrigued by recent high-energy study results for nearby galaxies with gamma-ray emission and in particular NGC~1068 that has been detected as a neutrino-emitting source by the Ice…
A tera-electronvolt afterglow from a narrow jet in an extremely bright gamma-ray burst 221009A
LHAASO Collaboration
Some gamma-ray bursts (GRBs) have an afterglow in the tera-electronvolt (TeV) band, but the early onset of this afterglow has not been observed. We report observations with the Lar…
Can one-zone hadronuclear model explain the hard-TeV spectrum of BL Lac objects?
Wei-Jian Li, Rui Xue, Guang-Bo Long +4
Context. The intrinsic TeV emission of some BL Lacs are characterized by a hard spectrum (the hard-TeV spectrum) after correcting for the extragalactic background light. The hard-T…
A spectral hardening in the Fermi-LAT Data of 1ES 0502+675
Yuhang Zeng, Dahai Yan, Wen Hu +1
The -ray spectral feature of the blazar 1ES 0502+675 is investigated by using Fermi Large Area Telescope (Fermi-LAT) Pass 8 data (between 100 MeV and 300 GeV) covering from 2008…
A Quasi-periodic Oscillation in the gamma-ray Emission from the Non-blazar Active Galactic Nucleus PKS 0521-36
Haiyun Zhang, Dahai Yan, Pengfei Zhang +2
Long-term gamma-ray variability of a non-blazar Active Galactic Nucleus (AGN) PKS 0521-36 is investigated by using Fermi-LAT pass 8 data covering from 2008 August to 2021 March. Th…
Correlations between -ray luminosity and magnetization of the jet as well as relativistic electron injection power:cases for Mrk 421, 3C 454.3 and 3C 279
Wen Hu, Da-hai Yan, Qiang-lin Hu
By fitting high-quality and simultaneous multi-wavelength (MWL) spectral energy distributions (SEDs) at multiple epochs with a one-zone leptonic jet model, we study jet properties…
