Ultra-high energy cosmic rays detected by Auger and AGASA. Corrections for galactic magnetic field deflections, source populations, and arguments for multiple components
(2010)
Context. The origin and composition of ultra-high energy cosmic rays (UHECRs) remain unclear. Possible sources include active galactic nuclei – selected by various criteria – and extragalactic magnetars. Aims. We aim to ...
Connection between UHECR's and supermassive relic particles
(Elsevier B.V., 2001-04-01)
One of the models proposed for the origin of ultra high energy cosmic rays (UHECR's) suggests that these events are the decay products of relic superheavy metastable particles, which we call S particles. These particles ...
Ultra-high energy cosmic rays detected by the Pierre Auger observatory. First direct evidence, and its implications, that a subset originate in nearby radiogalaxies
(2008)
(abridged) The Pierre Auger Collaboration has reported 27 Ultra-High Energy Cosmic Ray Events (UHECRs) with energies above 56 EeV and well determined arrival directions as of 2007 August 31. They find that the arrival ...
