Superdiffusion of cosmic rays in the vicinity of their accelerators and the resulting -ray emission
Zhaodong Shi, Guangwei Wang, Rui-zhi Yang
We study the distribution of cosmic rays (CRs) in the vicinity of their accelerators, assuming that the transport of CRs in the interstellar medium surrounding the accelerators is…
Microquasar Cygnus X-3 as the PeVatron powering the Cygnus Bubble
Zhaodong Shi, Guangwei Wang, Ruizhi Yang +1
The recent discovery by the LHAASO collaboration of a variable ultra-high-energy (UHE; 100 TeV) -ray source associated with the microquasar Cygnus X-3, with a spectrum…
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,…
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…
