New full-sky studies of the distribution of ultra-high-energy cosmic-ray arrival directions

A. Gálvez Ureña, L. Anchordoqui, M. Bianciotto +17

Ground-based full-sky studies of the angular distribution of arrival directions of ultra-high-energy cosmic rays require combining data from different observatories, such as the Pi…

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…

UHECR arrival directions in the latest data from the original Auger and TA surface detectors and nearby galaxies

Armando di Matteo, Luis Anchordoqui, Teresa Bister +13

The distribution of ultra-high-energy cosmic-ray arrival directions appears to be nearly isotropic except for a dipole moment of order per cent. None…

Propagation of ultra-high-energy cosmic rays in the magnetized cosmic web

Jihyun Kim, Dongsu Ryu, Soonyoung Roh +2

A high concentration of ultra-high-energy cosmic ray (UHECR) events, called a hotspot, was reported by the Telescope Array (TA) experiment, but its origin still remains unsolved. O…

Filaments of Galaxies as a Clue to the Origin of Ultra-High-Energy Cosmic Rays

Jihyun Kim, Dongsu Ryu, Hyesung Kang +2

Ultra-high-energy cosmic rays (UHECRs) are known to come from outside of our Galaxy, but their origin still remains unknown. The Telescope Array (TA) experiment recently identified…

Correlation between Ultra-high Energy Cosmic Rays and Active Galactic Nuclei from Fermi Large Area Telescope

Jihyun Kim, Hang Bae Kim

We study the possibility that the -ray loud active galactic nuclei (AGN) are the sources of ultra-high energy cosmic rays (UHECR), through the correlation analysis of their loca…

Revisit of Correlation Analysis between Active Galactic Nuclei and Ultra-High Energy Cosmic Rays

Hang Bae Kim, Jihyun Kim

We update the previous analysis of correlation between ultra-high energy cosmic rays (UHECR) and active galactic nuclei (AGN), using 69 UHECR events with energy …

Statistical Analysis of the Correlation between Active Galactic Nuclei and Ultra-High Energy Cosmic Rays

Hang Bae Kim, Jihyun Kim

We develop the statistical methods for comparing two sets of arrival directions of cosmic rays in which the two-dimensional distribution of arrival directions is reduced to the one…
