Towards extracting cosmic magnetic field structures from cosmic-ray arrival directions
We present a novel method to search for structures of coherently aligned patterns in ultra-high energy cosmic-ray arrival directions simultaneously across the entire sky. This method can be used to
UHECR mass composition at highest energies from anisotropy of their arrival directions
We propose a new method for the estimation of ultra-high energy cosmic ray (UHECR) mass composition from a distribution of their arrival directions. The method employs a test statistic (TS) based on

Ultrahigh energy nuclei in the galactic magnetic field
Observations are consistent with a significant fraction of heavy nuclei in the cosmic ray flux above a few times 1019 eV. Such nuclei can be deflected considerably in the Galactic magnetic field,
Propagation of ultrahigh energy cosmic rays in extragalactic magnetic fields: a view from cosmological simulations
We use the CRPropa code to simulate the propagation of ultra high energy cosmic rays (with energy $\geq 10^{18} \rm eV$ and pure proton composition) through extragalactic magnetic fields that have
Observation of a large-scale anisotropy in the arrival directions of cosmic rays above 8 × 1018 eV
TLDR
The Pierre Auger Collaboration reports the observation of thousands of cosmic rays with ultrahigh energies of several exa–electron volts, arriving in a slightly dipolar distribution, showing that they originate outside the Milky Way Galaxy.
Ultra-high-energy Cosmic Rays and the Large-scale Structure of the Galactic Magnetic Field
We study the deflection of ultra-high-energy cosmic-ray protons in different models of the regular Galactic magnetic field. Such particles have gyroradii well in excess of 1 kpc and their propagation
An Upper Limit on the Strength of the Extragalactic Magnetic Field from Ultra-high-energy Cosmic-Ray Anisotropy
If ultra-high-energy cosmic rays originate from extragalactic sources, the offsets of their arrival directions from these sources imply an upper limit on the strength of the extragalactic magnetic
Investigation of the Galactic Magnetic Field with Ultra-High Energy Cosmic Rays
We present a method to correct for deflections of ultra-high energy cosmic rays in the galactic magnetic field. We perform these corrections by simulating the expected arrival directions of protons
Mapping ultrahigh energy cosmic rays deflections through the turbulent galactic magnetic field with the latest rotation measure data
We study the influence of the random part of the Galactic magnetic field on the propagation of ultra high-energy cosmic rays. Within very mild approximations about the properties of the electron
Signatures of galactic magnetic lensing upon ultra high energy cosmic rays
We analyse several implications of lensing by the regular component of the galactic magnetic field upon the observed properties of ultra high energy cosmic rays. Magnetic fields deflect cosmic ray
Mapping deflections of extragalactic ultrahigh-energy cosmic rays in magnetohydrodynamic simulations of the local universe
We construct a map of deflections of ultrahigh-energy cosmic rays by extragalactic magnetic fields using a magnetohydrodynamical simulation of cosmic structure formation that realistically reproduces
