Nonlinear diffusive shock acceleration with upstream escape reproduces DAMPE observations
Han-Xiang Hu, Xing-Jian Lv, Xiao-Jun Bi +3
We develop a self-consistent nonlinear extension of diffusive shock acceleration that incorporates cosmic ray (CR) backreaction on the shock precursor together with a physically mo…
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…
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…
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…
Constraints on Lorentz-invariance violation in the neutrino sector from the ultrahigh-energy event KM3-230213A
Yu-Ming Yang, Xing-Jian Lv, Xiao-Jun Bi +1
Lorentz invariance is a fundamental symmetry of spacetime and serves as the cornerstone of modern physics, supporting the constancy of the speed of light. A crucial implication of…
Deciphering the spectral bumps of Galactic cosmic rays through gamma-ray observations of nearby molecular clouds
