Anisotropy-driven constraints on the transition from Galactic to extragalactic cosmic-ray sources
Teresa Bister, Foteini Oikonomou, Damiano F. G. Fiorillo
The spatial distribution of the cosmic-ray (CR) flux above exhibits a significant dipole in agreement with expectations from extragalactic sources following the l…
Search for UHE neutrinos from GRBs with the Pierre Auger Observatory
Yago Lema-Capeans
We report on the search for ultra-high-energy neutrinos from the prompt emission of gamma-ray bursts (GRBs) using Surface Detector (SD) data from Phase I of the Pierre Auger Observ…
The source of the cosmic-ray excess in the Centaurus region -- constraints on possible candidates, mass composition and cosmic magnetic fields
Teresa Bister
The most significant excess in the arrival directions of ultra-high-energy cosmic rays with energies is found in the direction of several interesting sour…
Probing UHECR sources - Constraints from cosmic-ray measurements
Teresa Bister
Ultra-high-energy cosmic rays (UHECRs) are the most energetic particles known - and yet their origin is still an open question. However, with the precision and accumulated statisti…
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…
Study of solar activity with AERA at the Pierre Auger Observatory
R. M. de Almeida
Solar activity events release vast amounts of energy, including radio waves, X-rays, ultraviolet radiation, and energetic particles, which interact with the ionosphere of the Earth…
Measuring the muon content of inclined air showers using AERA and the water-Cherenkov detectors of the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +360
We present a novel approach for assessing the muon content of air showers with large zenith angles on a combined analysis of their radio emission and particle footprint. We use the…
The large-scale anisotropy and flux (de-)magnification of ultra-high-energy cosmic rays in the Galactic magnetic field
Teresa Bister, Glennys R. Farrar, Michael Unger
We calculate the arrival direction distribution of ultra-high-energy cosmic rays (UHECRs) with a new suite of models of the Galactic magnetic field (GMF), assuming sources follow t…
The distribution of ultra-high-energy cosmic rays along the supergalactic plane measured at the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +364
Ultra-high-energy cosmic rays are known to be mainly of extragalactic origin, and their propagation is limited by energy losses, so their arrival directions are expected to correla…
Constraints on UHECR sources and extragalactic magnetic fields from directional anisotropies
Teresa Bister, Glennys R. Farrar
A dipole anisotropy in ultra-high-energy cosmic ray (UHECR) arrival directions, of extragalactic origin, is now firmly established at energies E > 8 EeV. Furthermore, the UHECR ang…
The Pierre Auger Observatory Open Data
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +358
The Pierre Auger Collaboration has embraced the concept of open access to their research data since its foundation, with the aim of giving access to the widest possible community.…
Anisotropies, large and small
Teresa Bister, Glennys Farrar
We report on several new results using anisotropies of UHECRs. We improve and extend the work of Ding, Globus and Farrar, who modeled the UHECR dipole assuming sources follow the d…
2022 report from the Auger-TA working group on UHECR arrival directions
A. di Matteo, L. Anchordoqui, T. Bister +13
After over 60 years, the powerful engines that accelerate ultra-high-energy cosmic rays (UHECRs) to the formidable energies at which we observe them from Earth remain mysterious. A…
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…

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…

Covering the celestial sphere at ultra-high energies
J. Biteau, T. Bister, L. Caccianiga +14
Despite deflections by Galactic and extragalactic magnetic fields, the distribution of ultra-high energy cosmic rays (UHECRs) over the celestial sphere remains a most promising obs…
