Origin of the high-energy spectral cutoff in gamma-ray pulsar halos
Qi-Ling Chen, Ming-Ming Kang, Kun Fang +3
The spectra of gamma-ray pulsar halos exhibit a clear cutoff feature at tens of TeV. This work investigates the origin of the spectral cutoff by interpreting the HAWC data of the G…
Resolving diffusion signatures in distant pulsar halos with current and future experiments
Yong-Jian Wei, En-Sheng Chen, Kun Fang +1
Pulsar halos provide a unique probe of cosmic-ray propagation in the vicinity of pulsars and have important implications for our understanding of particle diffusion in the interste…
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,…
Method for testing diffusive shock acceleration and diffusion propagation of 1-100 TeV cosmic electrons with multiwavelength observations of the Geminga halo and pulsar wind nebula
Weikang Gao, Li-Zhuo Bao, Kun Fang +3
Diffusive shock acceleration and diffusion propagation are essential components of the standard cosmic ray model. These theories are based on extensive observations of high-energy…
Discrete treatment of inverse Compton scattering: implications on parameter estimation in gamma-ray astronomy
Junji Xia, Xingjian Lv, Kun Fang +1
In gamma-ray astronomy and cosmic-ray physics, the continuous approximation of inverse Compton scattering (ICS) is widely adopted to model the evolution of electron energy. However…
Constraining anisotropic diffusion between Geminga and Earth with the cosmic-ray electron and positron spectrum
Junji Xia, Xiaojun Bi, Kun Fang +1
The gamma-ray halo surrounding Geminga suggests a notable reduction in cosmic-ray diffusion. One potential explanation for this phenomenon is the projection effect of slow diffusio…
A New Perspective on the Diffuse Gamma-Ray Emission Excess
Ensheng Chen, Kun Fang, Xiaojun Bi
The Large High-Altitude Air Shower Observatory (LHAASO) recently published measurements of diffuse Galactic gamma-ray emission (DGE) in the 10-1000 TeV energy range. The measured D…
