Astrophysical: Cosmic rays

  • Publication
    Forbush decreases, solar irradiance variations, and anomalous cloud changes
    Changes in the galactic cosmic ray (GCR) flux due to variations in solar activity may provide an indirect connection between the Sun's and the Earth's climates...

    Ground-based, very high energy gamma-ray astronomy, a tool for exploring the ultrarelativistic Universe
    The window of very high energy (VHE) gamma-ray astronomy was only opened 20 years ago by the first observation of TeV gamma-rays from the CRAB nebula. Since...

    Inside Volcanoes through cosmic-ray muon tomography
    The origin and structure of the Earth's crust is still a major question. Current measurements of the nearby crust are based largely on seismic, gravimetric and...

    MAGIC observations of the diffuse γ-ray emission in the vicinity of the Galactic center
    Aims: In the presence of a sufficient amount of target material, γ-rays can be used as a tracer in the search for sources of Galactic cosmic rays (CRs). Here we...

    MAGIC observations provide compelling evidence of hadronic multi-TeV emission from the putative PeVatron SNR G106.3+2.7
    Context. Certain types of supernova remnants (SNRs) in our Galaxy are assumed to be PeVatrons, capable of accelerating cosmic rays (CRs) to ~ PeV energies...
