Different Jet Dissipation Mechanisms Underlying the Variability in Blazars
Hong-bin Tan, Ruo-yu Liu
Blazars are among the most extreme classes of active galactic nuclei. They are powered by relativistic jets, but the way in which the jet energy is dissipated is still unclear. The…
Revisiting the XMM-Newton Observations of the Galactic Microquasar SS 433: Implications for the Origin of the Ultrahigh-Energy Emission Detected by LHAASO
Chao-Nan Tong, Hong-Bin Tan, Ruo-Yu Liu
Recently, the Large High Altitude Air Shower Observatory (LHAASO) detected ultrahigh-energy (UHE; photon energy E>100TeV) -ray emission toward SS 433, the microquasar embedded i…
A Model for Magnetic Reconnection as the Origin of TeV Outbursts from NGC 1275
Zhen-Jie Wang, Hong-Bin Tan, Ruo-Yu Liu
NGC 1275 showed two TeV -ray outbursts between November 2022 and January 2023, as detected by the Large High Altitude Air Shower Observatory (LHAASO). The source was also active…
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…
