LHAASO Detection of Ultra-High-Energy Gamma-Ray Emission toward the Giant Molecular Clouds
Zhen Cao, F. Aharonian, Y. X. Bai +310
The -ray from Giant molecular clouds (GMCs) is regarded as the most ideal tool to perform in-situ measurement of cosmic ray (CR) density and spectra in our Galaxy. We report the…
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,…
Uncertainty in Hadronic Diffuse -Ray Emission from the Temporal Stochasticity of Cosmic-Ray Sources
Xing-Jian Lv, Xiao-Jun Bi, Kun Fang +3
Diffuse -ray emission is a key probe of cosmic rays (CRs) distribution within the Galaxy. However, the discrepancies between observations and theoretical model expectations high…
Unified Solar Modulation Potential for Same-Charge Cosmic Rays and Implications for Local Interstellar Spectra
Meng-Jie Zhao, Xing-Jian Lv, Xiao-Jun Bi +2
The energy spectra of cosmic rays (CRs) below tens of GeV are significantly modulated by solar activity within the heliosphere. To investigate the properties of Galactic CRs, it is…
Prediction of lithium isotope fluxes using data-driven production cross sections
Meng-Jie Zhao, Xiao-Jun Bi, Kun Fang +2
Galactic cosmic rays (CRs) generally share common propagation features, leading to consistent spectral observations of secondary nuclei such as Li, Be, and B. However, the Li spect…
Deciphering the spectral bumps of Galactic cosmic rays through gamma-ray observations of nearby molecular clouds
Xing-Jian Lv, Xiao-Jun Bi, Kun Fang +2
The observed spectral bump in cosmic-ray (CR) proton and helium spectra, along with the phase and amplitude evolution of CR dipole anisotropy, provide plausible yet indirect eviden…
