The Correspondence between Leaky-box and Diffusion Models of Cosmic-Ray Propagation

The Astrophysical Journal
The leaky-box model and the attendant concept of path-length distribution of cosmic rays were invented in the mid-1960s. Even though versatile computational packages such as GALPROP and DRAGON with the diffusion approach are now available for analyzing ...

Galactic Cosmic-Rays after AMS02

, 2019
Presentation given at the "Anti-deuteron 2019" conference at UCLA (Los Angeles) on March 27, 2019. Abstract: The current generation of cosmic-ray (CR) experiments in the GeV-TeV range has reached an unprecedented level of precision, unveiling fine-details of the energy spectra. The interpretation of these measurements could require a profound revision

Impact of Anisotropic Cosmic-Ray Transport on the Gamma-Ray Signatures in the Galactic Center

The Astrophysical Journal
The very high energy (VHE) emission of the central molecular zone (CMZ) is rarely modeled in 3D. Most approaches describe the morphology in 1D or simplify the diffusion to the isotropic case.

Galactic Cosmic-Ray Background Deduction Method Based on Empirical Mode Decomposition

The Astrophysical Journal
The inversion of the relative content and spatial distribution characteristics of radioactive elements on the lunar surface, as inferred from gamma-ray spectrometer data, holds substantial importance for forecasting lunar surface compositions. During the

Recurrent variations of anomalous oxygen in association with a corotating interaction region

Annales Geophysicae
The fluxes of anomalous oxygen (<i>E</i> ranging from 3.5-6.8 MeV/amu), as measured by the EPAC instrument on ULYSSES, show a recurrent variation with the solar rotation period, which is anticorrelated with the fluxes of particles accelerated

Search for Galactic Cosmic Ray Sources with H.E.S.S

, 2011
Supernova remnants (SNRs) are the prime candidates for the acceleration of the Galactic Cosmic Rays. Tracers for interactions of Cosmic Rays with ambient material are gamma rays at TeV energies, which can be observed with ground based Cherenkov ...
