Spectral Softenings, Composition Bump, and Anisotropy Transition: A Consistent Picture of Cosmic-Ray Origin Below the Knee
Xulin Dong, Yuhua Yao, Shuwang Cui +1
Recent DAMPE measurements of individual cosmic-ray components, including carbon, oxygen, and iron, reveal distinct spectral softenings below the knee. The energy spectrum, mass com…

Two kinds of Galactic source populations could explain the cosmic-ray observation up to the "knee" region
Furong Li, Wei Liu, Yali Shao +1
Observations of diffuse gamma rays above hundreds of TeV from the Galactic disk provide strong evidence for the existence of PeV cosmic-ray accelerators--so-called PeVatrons--in th…

New Insights on Gamma-Ray Burst Radiation Mechanisms from Multiwavelength Observations
Yu-Hua Yao, Fang-Sheng Min, Shi Chen +1
The study of high-energy gamma-ray emission from gamma-ray bursts (GRBs) involves complex synchrotron radiation and synchrotron self-Compton scattering (SSC) mechanisms with multip…
