Scaler data from the Pierre Auger Observatory as a proxy of solar activity

C. Taricco, I. Bizzarri, C. Dionese +1

Solar activity variations strongly impact the modulation of the flux of low-energy Galactic Cosmic Rays (GCRs) reaching the Earth. The secondary particles, which originate from the…

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…

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…

Uncertainties in the Estimation of Air Shower Observables from Monte Carlo Simulation of Radio Emission

Carlo S. Cruz Sanchez, Patricia M. Hansen, Matias Tueros +2

The detection of extensive air showers (EAS) induced by cosmic rays via radio signals has undergone significant advancements in the last two decades. Numerous ultra-high energy cos…

Quasar Redshifts: The Intrinsic Component

Peter M. Hansen

The large observed redshift of quasars has suggested large cosmological distances and a corresponding enormous energy output to explain the brightness or luminosity as seen at eart…

Astronomical Redshifts of Highly Ionized Regions

Peter M. Hansen

Astronomical or cosmological redshifts are an observable property of extragalactic objects and have historically been wholly attributed to the recessional velocity of that object.…

A comprehensive study of shower to shower fluctuations

P. M. Hansen, J. Alvarez-Muniz, R. A. Vazquez

By means of Monte Carlo simulations of extensive air showers (EAS), we have performed a comprehensive study of the shower to shower fluctuations affecting the longitudinal and late…
