VHE gamma-ray intranight variability from BL Lacertae during the extreme flaring state of 2022
K. Abe, S. Abe, A. Abhishek +297
BL Lacertae (BL Lac), the archetypal blazar of its subclass and one of the most studied blazars in the last decades, has undergone a series of major multi-wavelength outbursts sinc…
Long-term calibration and validation of stability of the Auger Engineering Radio Array using the diffuse Galactic radio emission
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +356
The Auger Engineering Radio Array (AERA) measures radio emission from high-energy extensive air showers. Consisting of 153 autonomous radio-detector stations spread over \,km$^…
Quasi-constant time gap in multiple rings of elves
The Pierre Auger Collaboration, A. Abdul Halim, P. Abreu +359
We present evidence that the time delay between the multiple rings of elves is not caused by the ground reflection of the electromagnetic pulse produced by intracloud lightning. To…
The Scintillator Surface Detector of the Pierre Auger Observatory
The Pierre Auger Collaboration
Data collected so far by the Pierre Auger Observatory have enabled major advances in ultra-high energy cosmic ray physics and demonstrated that improved determination of masses of…
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…
