Abstract Decay or annihilation products of superheavy dark matter (SHDM) could be responsible for the end of the ultra-high energy cosmic ray (UHECR) spectrum. In this case, the south array of the Pierre Auger Observatory should observe in the future a significant anisotropy of UHECR arrival directions towards the galactic center. Here we use the already existing data of the SUGAR array to test this possibility. If decaying SHDM is distributed according a Navarro–Frenk–White (NFW) dark matter…

Clustering Properties of Ultra-High-Energy Cosmic Rays and the Search for Their Astrophysical Sources
The arrival directions of ultrahigh energy cosmic rays (UHECRs) may show anisotropies on all scales, from just above the experimental angular resolution up to medium scales and dipole anisotropies.
Astrophysical origins of ultrahigh energy cosmic rays
In the first part of this review we discuss the basic observational features at the end of the cosmic ray (CR) energy spectrum. We also present there the main characteristics of each of the

Status of particle physics solutions to the UHECR puzzle
Abstract The status of solutions to the ultra-high energy cosmic ray puzzle that involve particle physics beyond the standard model is reviewed. Signatures and experimental constraints are discussed
Anisotropies and clustering of extragalactic cosmic rays
Deviations from isotropy have been a key tool to identify the sources and the primary type of cosmic rays (CRs) at low energies. We argue that anisotropies due to blind regions induced by the

Ultra-high energy cosmic rays from annihilation of superheavy dark matter
Abstract We consider the possibility that ultra-high energy cosmic rays originate from the annihilation of relic superheavy dark matter. We find that a cross-section of 〈 σ A v 〉∼10 −26  cm 2 ( M X

We study the decays of metastable superheavy particles as the source of ultrahigh energy cosmic rays (UHE CR). These particles are assumed to constitute a tiny fraction {xi}{sub X} of cold dark
Signatures of topological defects
We argue that due to various restrictions cosmic strings and monopole-string networks are not likely to produce the observed flux of ultrahigh energy cosmic rays (UHECR). Among the topological

Matter creation via vacuum fluctuations in the early Universe and observed ultrahigh energy cosmic ray events
