Abstract The Pierre Auger Observatory, located on a vast, high plain in western Argentina, is
the world׳ s largest cosmic ray observatory. The objectives of the Observatory are to probe …

An overview of the multi-messenger capabilities of the Pierre Auger Observatory is
presented. The techniques and performance of searching for Ultra-High Energy neutrinos …

Ultra-high energy (UHE) photons with energies around 1 EeV (1 EeV= 1018 eV) and
above have not yet been identified (see Bleve & Pierre Auger Collaboration 2015 and …

Modern large-scale astroparticle setups measure high-energy particles, gamma rays,
neutrinos, radio waves, and the recently discovered gravitational waves. Ongoing and future …

A produção de partículas energéticas no Universo continua sendo um dos grandes
mistérios da ciência atual. Os mecanismos de aceleração de partículas em fontes …

The Galactic magnetic field (GMF) strongly affects the arrival distribution of charged cosmic
rays, thereby obscuring their sources. A compact source of high-energy neutrons would …

In this paper the production of neutrinos and photons by ultra high energy cosmic rays
(UHECR) interacting with the extragalactic background radiation is studied. Centaurus A is …

Our planet is constantly hit by a stream of energetic subatomic particles, which are known as
'cosmic rays'. These particles are mostly protons, but also heavier nuclei, as well as small …

Over the last decade a number of important observational results have been reported using
data from the Pierre Auger Observatory. We shall review some of the recent key findings that …
