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…
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…
Observations of the Fermi bubbles and the Galactic center excess with the DArk Matter Particle Explorer
F. Alemanno, Q. An, P. Azzarello +145
The DArk Matter Particle Explorer (DAMPE) is a space-borne high-energy particle detector that surveys the -ray sky above with a peak acceptance of $\sim 0.2~\rm…
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…
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…
A rigorous solution to the superluminal issue in the diffusion equation
Xing-Jian Lv, Xiao-Jun Bi, Kun Fang +2
Superluminal propagation is an intrinsic problem in the diffusion equation and has not been effectively addressed for a long time. In this work, a rigorous solution to this issue i…
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…
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…
