Search for Spatial Correlations of Neutrinos with Ultra-High-Energy Cosmic Rays

The ANTARES collaboration, A. Albert, S. Alves +1042

For several decades, the origin of ultra-high-energy cosmic rays (UHECRs) has been an unsolved question of high-energy astrophysics. One approach for solving this puzzle is to corr…

The UHECR dipole and quadrupole in the latest data from the original Auger and TA surface detectors

Peter Tinyakov, Luis Anchordoqui, Teresa Bister +13

The sources of ultra-high-energy cosmic rays are still unknown, but assuming standard physics, they are expected to lie within a few hundred megaparsecs from us. Indeed, over cosmo…
