A Multi-messenger Search for a Nearby Microquasar Contributor to the Cosmic Ray Knee
Lin Nie, Hua Yue, Yi-Qing Guo +1
Recently, LHAASO has detected five microquasars with high confidence, which are associated with SS 433, V4641 Sgr, GRS 1915+105, MAXI J1820+070, and Cygnus X-1, respectively. Excep…
Joint constraint on the propagation origin of the cosmic-ray spectral knee from energy spectrum and anisotropy observations
Hua Yue, Lin Nie, Yi-Qing Guo +1
The origin mechanism of the cosmic-ray knee region remains an unresolved mystery, with acceleration, interaction, and propagation models drawing significant attention. The latest e…
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…
X-ray Binaries: a potential dominant contributor to the cosmic ray spectral knee structure
Hua Yue, Jianli Zhang, Yuhai Ge +5
``PeVatrons" refer to astrophysical sources capable of accelerating particles to energies PeV and higher, potentially contributing to the cosmic ray spectrum in the knee regi…
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…
