High-energy particles are extragalactic Cosmic rays are high-energy particles arriving from space; some have energies far beyond those that human-made particle accelerators can achieve. The sources of higher-energy cosmic rays remain under debate, although we know that lower-energy cosmic rays come from the solar wind. The Pierre Auger Collaboration reports the observation of thousands of cosmic rays with ultrahigh energies of several exa–electron volts (about a Joule per particle), arriving in… Expand

Acceleration of petaelectronvolt protons in the Galactic Centre
TLDR
Deep γ-ray observations with arcminute angular resolution of the region surrounding the Galactic Centre are reported, which show the expected tracer of the presence of petaelectronvolt protons within the central 10 parsecs of the Galaxy, and it is proposed that the supermassive black hole Sagittarius A* is linked to this PeVatron.

TLDR
It is shown that, in the case of UHECRs produced by gamma-ray bursts or rare types of supernova explosions that took place in the Milky Way in the past, the change in UH ECR composition can result from the difference in diffusion times for different species. Expand
