Nature, 1948 IT is important to decide whether or not the main sources of the cosmic ray particles are external to our galaxy. An external source seems, at first sight, to be established by the observed isotropy of the cosmic rays incident on the earth. But it has been claimed by a number of authors that this isotropy is simply a consequence of a magnetic field ...

Particles, 2023 Cosmic ray air showers are a phenomenon that can be observed on Earth when high-energy particles from outer space collide with the Earth’s atmosphere. These energetic particles in space are called primary cosmic rays and consist mainly of protons (about ...

EPJ Web of Conferences, 2015 The multi-facet nature of the origin of cosmic rays is such that some of the problems currently met in our path to describing available data are due to oversimplified models of CR acceleration and transport, and others to lack of knowledge of the ...

The origin of cosmic rays [PDF]
Journal of Physics G: Nuclear and Particle Physics, 1999 It is generally regarded that the bulk of cosmic rays originate in the Galaxy and that those below the 'knee' (the rapid steepening in the energy spectrum) at a few PeV come from Galactic supernovae, the particles being accelerated by the shocks in the supernova remnants.

New generation Cherenkov telescope array: HADAR and its performance introduction
Nuclear Physics BAstrophysical very high energy (VHE) gamma-rays are believed to result almost exclusively from the interactions of populations of highly relativistic particles with ambient matter or photon fields.

One century of cosmic rays – A particle physicist's view
EPJ Web of Conferences, 2015 Experiments on cosmic rays and the elementary particles share a common history that dates back to the 19th century. Following the discovery of radioactivity in the 1890s, the paths of the two fields intertwined, especially during the decades after the ...

The origin of cosmic rays and TeV gamma-ray astronomy
EPJ Web of Conferences, 2013 Cosmic rays are accelerated to high energies in Galactic and extragalactic objects like Supernova remnants (SNR) and active galactic nuclei (AGN). How these accelerators work and how efficient they accelerate different types of particles to energies of ...
