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 ...

Cosmic-Ray Bursts [PDF]

Physical Review, 1933
In cloud-chamber experiments the frequent occurrence of associated tracks has been observed.(1) It has been pointed out that a simple binary collision cannot explain all the associated tracks.(2)

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 ...

Origin of small-scale anisotropies in Galactic cosmic rays [PDF]

, 2016
The arrival directions of Galactic cosmic rays are highly isotropic. This is expected from the presence of turbulent magnetic fields in our Galactic environment that repeatedly scatter charged cosmic rays during propagation.

Messengers of the Universe-Cosmic Rays Exploring Supermassive Black Holes

Galaxies, 2020
Cosmic rays were discovered over one hundred years ago but there are still unsolved problems. One of the hot problems is the origin of cosmic rays of the highest energies.

Antiproton Flux, Antiproton-to-Proton Flux Ratio, and Properties of Elementary Particle Fluxes in Primary Cosmic Rays Measured with the Alpha Magnetic Spectrometer on the International Space Station.

Physical Review Letters, 2016
A precision measurement by AMS of the antiproton flux and the antiproton-to-proton flux ratio in primary cosmic rays in the absolute rigidity range from 1 to 450 GV is presented based on 3.49×10^{5} antiproton events and 2.42×10^{9} proton events.

Protostars: Forges of cosmic rays? [PDF]

, 2016
Galactic cosmic rays (CR) are particles presumably accelerated in supernova remnant shocks that propagate in the interstellar medium up to the densest parts of molecular clouds, losing energy and their ionisation efficiency because of the presence of ...
