Small-scale Cosmic-Ray Anisotropy Observed by the GRAPES-3 Experiment at TeV Energies
The Astrophysical JournalGRAPES-3 is a mid-altitude (2200 m) and near-equatorial (11.°4N) air shower array, overlapping in its field of view for cosmic-ray observations with experiments that are located in the Northern and Southern Hemispheres. We analyze a sample of 3.7 × 10 ^9

Cosmic ray albedo gamma rays from the quiet sun [PDF]
We estimate the flux of gamma-rays that result from collisions of high energy galactic cosmic rays with the solar atmosphere. An important aspect of our model is the propagation of cosmic rays through the magnetic fields of the inner solar systems.

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

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

Impact of Anisotropic Cosmic-Ray Transport on the Gamma-Ray Signatures in the Galactic Center
The Astrophysical JournalThe 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 JournalThe 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 GeophysicaeThe 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 ...
