Search for Galactic cosmic ray sources: The multimessenger approach

EPJ Web of Conferences, 2015
The search for the sources of high-energy cosmic rays (CRs) has made significant progress the past decade. By including multimessenger methods, the general picture of the presence of a Galactic component at low energies and an extragalactic one at the ...

Origin of the Ultrahigh-Energy Cosmic Rays and their Spectral Break

, 2010
The energy spectrum, composition and arrival directions of ultrahigh energy cosmic rays (UHECRs) with energy above the cosmic ray ankle, measured by the Pierre Auger Observatory, are inconsistent if their origin is assumed to be extragalactic.

Estimating Soft X‐Ray Emission From Uranus's Magnetosheath

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract Soft X‐ray emission occurs within planetary magnetosheaths when highly charged solar wind ions undergo charge exchange with neutrals. The emission can provide dynamic views of the magnetosheath and cusps, allowing for investigations of the solar wind interaction with a planetary magnetosphere.

Correlation Patterns of Muon Flux With Vertical Atmospheric Profiles: Insights From Monte Carlo Simulations

Journal of Geophysical Research: Space Physics, Volume 130, Issue 11, November 2025.
Abstract The production, attenuation, and absorption of secondary cosmic rays (SCR) are influenced by atmospheric parameters such as air pressure and temperature. To reliably correlate SCR flux measurements with atmospheric ionization driven by energetic particle precipitation, these dependencies must be quantified.

Role of line-of-sight cosmic ray interactions in forming the spectra of distant blazars in TeV gamma rays and high-energy neutrinos

, 2011
Active galactic nuclei (AGN) can produce both gamma rays and cosmic rays. The observed high-energy gamma-ray signals from distant blazars may be dominated by secondary gamma rays produced along the line of sight by the interactions of cosmic-ray protons ...
