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…
Charge-dependent spectral softenings of primary cosmic-rays below the knee
DAMPE Collaboration, Francesca Alemanno, Qi An +146
In most particle acceleration or propagation theories, the characteristic features of the cosmic ray spectra due to acceleration limits or propagation phase changes are charge depe…
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…
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…
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 hig…
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…
