Observation of the Moon and Sun shadows with cosmic rays at an average energy of eV
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +346
Interactions of cosmic rays with the Moon and the Sun produce deficits in their arrival-direction distributions relative to an isotropic flux. Such shadows have been observed previ…
Anomaly detection in Fink. I. Discovery, follow-up, and classification of unusual sources
M. V. Pruzhinskaya, M. V. Kornilov, A. V. Dodin +19
Modern wide-field time-domain surveys produce alert streams whose scientific potential is often concentrated in rare and unusual events. Efficient discovery therefore requires auto…
Search for ultra-high energy neutrons from Galactic sources with the Pierre Auger Observatory
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +357
Deflections in the propagation of charged ultra-high-energy cosmic rays (UHECRs) caused by magnetic fields make the identification of their sources challenging. On the other hand,…
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 Pierre Auger Observatory: Contributions to the 39th International Cosmic Ray Conference (ICRC 2025)
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +352
The Pierre Auger Observatory, located in La Pampa Amarilla, Argentina, has been continuously acquiring data since 2004. It comprises a surface detector array covering 3,000 km…
The influence of environmental effects on Type Ia Supernovae Standardization
Anastasia Baluta, Maria Pruzhinskaya, Philippe Rosnet +1
Type Ia Supernovae (SNe Ia) are used as reliable cosmic distance indicators and their standardization is necessary for a more accurate measurement of the cosmological parameters of…
