The scintillator surface detector of the Pierre Auger observatory

Adila Abdul Halim, P. Abreu, M. Aglietta, I. Allekotte et autres

Abstract 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 primary cosmic-ray particles, preferably on an event-by-event basis, is necessary for understanding their origin …

Scaler Rates from the Pierre Auger Observatory: A New Proxy of Solar Activity

A. Abdul Halim, P. Abreu, M. Aglietta, I. Allekotte et autres

Abstract The modulation of low-energy galactic cosmic rays reflects interplanetary magnetic field variations and can provide useful information on solar activity. An array of ground-surface detectors can reveal the secondary particles, which originate from the interaction of cosmic rays with the atmosphere. …

The Distribution of Ultrahigh-energy Cosmic Rays along the Supergalactic Plane Measured at the Pierre Auger Observatory

A. Abdul Halim, P. Abreu, M. Aglietta, I. Allekotte et autres

Abstract Ultrahigh-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 correlate with the large-scale structure of the local Universe. In this work, we investigate the …

Search for the Anomalous Events Detected by ANITA Using the Pierre Auger Observatory

A. Abdul Halim, P. Abreu, M. Aglietta, I. Allekotte et autres

A dedicated search for upward-going air showers at zenith angles exceeding 110° and energies E>0.1 EeV has been performed using the Fluorescence Detector of the Pierre Auger Observatory. The search is motivated by two "anomalous" radio pulses observed by the ANITA flights …

The Pierre Auger Observatory open data

A. Abdul Halim, P. Abreu, M. Aglietta, I. Allekotte et autres

Abstract 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. A gradual process of release began as early as 2007 when 1% …

AugerPrime surface detector electronics

Adila Abdul Halim, P. Abreu, M. Aglietta, P. Allison et autres

Abstract Operating since 2004, the Pierre Auger Observatory has led to major advances in our understanding of the ultra-high-energy cosmic rays. The latest findings have revealed new insights that led to the upgrade of the Observatory, with the primary goal of obtaining …

Arrival Directions of Cosmic Rays above 32 EeV from Phase One of the Pierre Auger Observatory

P. Abreu, M. Aglietta, Justin M. Albury, I. Allekotte et autres

Abstract A promising energy range to look for angular correlations between cosmic rays of extragalactic origin and their sources is at the highest energies, above a few tens of EeV (1 EeV ≡ 1018 eV). Despite the flux of these particles being …
